The Future's Bright for Transport Networks

The world of telecommunications is driven by changes in consumption patterns. As illustrated in the following figure, telecommunications is moving from voice PSTN to voice over IP (VoIP), from Time Division Multiplexing (TDM) leased lines to Ethernet virtual private networks (VPNs), from TDM-based 2G and 2.5G mobile networks to 3G/LTE/4G packet-based networks, and from simple best effort (BE) high speed Internet (HSI) access to advanced triple play networks for small and medium businesses (SMB) and home use. Telecom network infrastructures must be able to support the rapidly growing number of packet-based services and applications as well as high-capacity transport pipes. Existing SDH transport networks are no longer equal to the task at hand. Today's challenge is to build an infrastructure that maximizes bandwidth capacity while minimizing costs.

1 Introduction

Introduction XDM General Description

1-2 ECI Telecom Ltd. Proprietary 417006-2002-0H3-D06

Operators must provide a carrier class standard of service with more bandwidth at less cost per bit, and still get a satisfactory return on investment (ROI).

Figure 1-1: Converged transport network

Today's demands for multimedia-based services and corporate intranet applications requiring large amounts of bandwidth are causing a shortfall in available resources. With the trend of shifting more services from the intranet environment to the cloud, this problem is only expected to grow. Carriers and SPs require a highly scalable broadband and metro aggregation infrastructure to deliver increasing amounts of data traffic to their customers, seamlessly and transparently.

SDH and PDH have long been dominant technologies in WAN and PSTN networks that were primarily designed to carry voice. The growing demand for additional capacity led to increased SDH deployment in metropolitan and core networks. Recently, these networks have been struggling to cope with a huge explosion of Ethernet service data traffic.

XDM General Description Introduction


Network operators are increasingly using Ethernet (10BaseT, FE, GbE, and 10 GbE) as the connection technology of choice for data communications across public networks. Ethernet services offer a simpler, more suitable and cost-effective solution for transparent LAN-to-LAN connectivity. The capacity needed to meet these new demands has outpaced SDH's ability to cost effectively scale up to higher speeds; metro WDM has therefore become a common solution for dramatically increased bandwidth on existing fiber infrastructure.

What operators need for their next generation transport networks is an infrastructure that combines the classic carrier class advantages of SDH (remote OAM&P, guaranteed latency, reliability, and protection) and the capacity of WDM with the simplicity, ubiquity, scalability, and low cost of Ethernet.

All-Native Capabilities for Optimal Performance

ECI's XDM platforms provide All-Native support for each type of technology. ECI's All-Native approach supports the full cycle of migration, enabling you to evolve your network gradually from TDM-based transport to a mix of TDM and Ethernet to a pure packet-based network, while maintaining native handling of both TDM and Ethernet. The same equipment can be used throughout the full life cycle of the transport network as it evolves:

Beginning with TDM traffic carried over TDM.

Gradually adding in Ethernet traffic services, where both Ethernet and TDM are delivered over TDM.

Increasing packet services to match customer demand, with Ethernet and TDM both processed natively and independently and delivered over TDM or Ethernet, as appropriate.

All these options can be carried over WDM, providing an additional dimension of scale for future growth.



Figure 1-2: Dual matrix approach

All-Native TDM and packet processing offers the most cost-efficient traffic handling in a mixed environment. Risk is minimized since infrastructure investments are linked to service scaling, without any complex, risky, or costly encapsulation schemes.

The All-Native approach make the XDM platforms ideal for network convergence at the metro/access aggregation level, reducing the risks associated with the shift to packet-based transport, protecting your legacy investment, and giving you a smooth migration path to NG networks with seamless integration with CESR platforms.

Carrier Class Ethernet and MPLS Ethernet service, the preeminent LAN technology, is now becoming the dominant service for the metro domain (WAN) as well. Consumers require guaranteed service delivery of the appropriate quality, expecting operators to provide differentiated services with comprehensive carrier class capabilities, from access to core.

MultiProtocol Label Switching (MPLS) is a mechanism for transporting data using a connection-oriented approach. Standardized by the IETF, MPLS is a scalable protocol-agnostic mechanism designed to carry both circuit and packet traffic over virtual circuits known as LSPs. MPLS fits into the category of packet-switched networks, falling in between the traditional OSI definitions of the Data Link Layer (Layer 2) and the Network Layer (Layer 3). MPLS makes packet-forwarding decisions based on the contents of the label without examining the packet itself.

MPLS provides a unified data-carrying service for circuit-like packet-switching client data. MPLS can be used to carry many different kinds of traffic, including IP packets, native ATM, and Ethernet frames. MPLS has gradually been replacing traditional transport technologies, such as frame relay and ATM, mostly because it is better aligned with current and future technology needs.



Many network operators now deploy MPLS networks in response to the massive continued growth of data traffic, the demand for complete service offerings, and the development of network convergence strategies. Ethernet interfaces and Ethernet/MPLS services are the main toolbox supporting the MPLS network operator's strategic goals.

MPLS as a transport layer for metro Carrier Ethernet services, rather than using Ethernet as both transport and service layers, enhances the Ethernet service, enabling it to meet a complete carrier class standard. MPLS addresses all key attributes defined by MEF for Carrier Ethernet:

Hard Quality of Service (QoS), with guaranteed end-to-end (E2E) Service Level Agreements (SLAs) for business, mobile, and residential users that enables efficient differentiated services, allowing service providers (SPs) to tailor the level of service and performance to the requirements of their customers (real-time, mission-critical, BE, etc.), as well as assuring the necessary network resources for Committed Information Rate (CIR) and Extended Information Rate (EIR).

Reliability, with a robust, resilient network that can provide uninterrupted service across each path. This includes network protection of less than 50 msec using link/node Fast ReRoute (FRR) and meeting a five 9s standard of E2E service availability.

Scalability of both services and bandwidth, ranging from megabits to hundreds of gigabytes with variable granularity and hundreds of thousands of flows supporting controlled scalability for both the number of elements and the number of services on the network.

End to End Service Management through a single comprehensive Network Management System (NMS) that provisions, monitors, and controls many network layers simultaneously. Advancement in the management of converged networks takes advantage of the condensed transport layer for provisioning and troubleshooting while presenting operators with tiered physical and technology views that are familiar and easy to navigate. The comprehensive NMS simplifies operations by allowing customers and member companies to monitor and/or control well-defined and secure resource domains with partitioning down to the port.

Security, with a safe environment that protects subscribers, servers, and network devices, blocking malicious users, Denial of Service (DoS), and other types of attacks. Use of provider network constraints, as well as complete traffic segregation, ensures the highest level of security and privacy for even the most sensitive data transmissions.



Figure 1-3: Carrier class Ethernet requirements

However, until recently MPLS encountered difficulties expanding beyond the network core towards the metro and access domains. This was mainly due to two reasons:

The historical linkage between MPLS and IP switch/routers. Service providers were reluctant to introduce these high cost NEs on a large scale. Introduction of IP elements would also impose a steep learning curve on metro network managers needing to adapt to an IP configuration.

The distributed control plane was another discouraging factor. Service providers were reluctant to pay the cost associated with having control plan functionality distributed and integrated into each node across an MPLS-based network, and were reluctant to relinquish network control.

To address these hesitations, MPLS-TP has been introduced.

What is MPLS-TP? MPLS Transport Profile (MPLS-TP) is a connection-oriented packet-switched (CO-PS) application for Layer 2 transport network technology that incorporates elements of both MPLS and PW architectures, such as the MPLS forwarding paradigm and PW Emulation Edge to Edge (PWE3) client mapping. MPLS-TP is based on the same architectural principles of layered networking used in transport network technologies like SDH, SONET, and OTN.

MPLS-TP is currently being defined under the auspices of the IETF in cooperation with the ITU-T. The emerging MPLS-TP standard defines a feature list most relevant for metro transport networks, and supports packet transport services with a degree of predictability similar to that of existing transport networks.



The MPLS-TP design is a natural extension of work begun by ITU-T (SG15), in a process similar to the development of T-MPLS. In February 2008, the ITU-T and IETF agreed to work jointly on the MPLS-TP design. Specifications are defined in a number of RFCs. Many SPs are now requiring an infrastructure that will also be capable of supporting MPLS-TP.

MPLS-TP is initially planned as a low-cost Layer 2 technology that provides QoS, E2E OAM, and protection switching. Features not relevant to CO-PS applications are removed, such as:

Connectionless models

IP in data plane

Penultimate Hop Popping (PHP) for E2E OAM

Additional mechanisms supporting critical transport functionality are added, including supplemental OAM, resiliency, bidirectional LSPs, new protection schemes, and control/management features that enable maximum synergy with existing optical transport network operations and management paradigms.

Essential features of MPLS-TP include:

Strict CO-PS network technology basis.

Operates independently of clients and associated control networks, enabling network operators to maintain a clear separation between their own robust packet transport network designs and the services and means used to carry customer traffic.

Supports a wide range of client layer networks and server layer networks, including OTN, SDH, PDH, and ETH.

Robust OAM capabilities and resilience mechanisms without relying on the use of a control plane.

Connection management via management or control plane.

Common management and control of multi-layer packet and optical transport networks.

MPLS-TP uses the MPLS header with standard label swapping and stacking and PWE3 mapping, supporting P2P, P2MP, and MP2MP connections that match the ones already defined for MPLS and H-VPLS architectures. MPLS-TP also supports bidirectional P2P connections (bidirectional LSPs) by matching forward and backward connections along the same path. MPLS-TP does not use MP2MP LSPs, Electronic Commerce Messaging Protocol (ECMP), or PHP.

MPLS-TP QoS mechanisms are the same as those of MPLS-TE. MPLS-TP applies QoS on a per-connection basis. When working with hierarchical LSPs, QoS is managed independently at each level.



The MPLS-TP protocol enables more affordable E2E MPLS deployments by streamlining operations models and consolidating/simplifying network topologies. For example, one of the key elements is eliminating the costs associated with distributed control plane functionality being integrated into each node across an MPLS-based network. This is accomplished through the use of a more affordable transport-oriented static configuration through a transport-grade NMS, helping operators reduce their OPEX significantly and get networks ready to offer true NG service convergence.

ECI, as a leader in MPLS and MPLS-TP technology, is participating in the standards development process as it unfolds. ECI's MPLS components are designed to be future proof, capable of incorporating and supporting new standard requirements as they are defined. ECI is one of the first vendors in the industry to implement MPLS-TP across all of its transport products in a holistic approach to network design and configuration that provides smooth interoperability of MPLS-TP with IP/MPLS.

Figure 1-4: MPLS-TP in an E2E network configuration



The XDM's MPLS-TP solution is based on the following building blocks:

Management: LightSoft NMS supports point-and-click MPLS-TP static tunnel and service provisioning, with smooth integration into dynamic IP/MPLS service provisioning.

Forwarding: Bidirectional tunnels enable forward and backward traffic following the same path. Efficient traffic management functionality utilizes bidirectional paths for traffic and OAM, fully compatible with standard MPLS, with forwarding based on LSP/PW and labels.

Protection: Resilient protection offered at multiple levels, including sub-50 msec 1:1 linear protection based on Bidirectional Forwarding Detection (BFD) hardware-based OAM, a combination of provider edge (PE) dual homing based on pseudowire (PW) redundancy and customer edge (CE) dual homing based on multi-chassis LAG (MC-LAG), and Fast ReRoute (FRR) for sub-50 msec protection against tunnel, link, and transit node failures, with sophisticated dual protection options. Enhanced optical protection mechanisms are available for all topologies, including ring and star.

OAM: OAM functionality is supported within the data plane, independent of the control plane. XDM platforms support MPLS tunnel OAM based on Y.1711, Ethernet link OAM based on IEEE 802.3-05, and service OAM based on IEEE 802.1ag. Inband OAM is implemented using associated channels, with PM and FM at the LSP level.

Control Plane: XDM offers an optional ASON (GMPLS-based) implementation for dynamic provisioning and restoration, with a choice of 1++, 1+R, and 1+1+R restoration.



Comprehensive Set of Services The Metro Ethernet Forum (MEF) has defined carrier class transport solutions for emerging Ethernet-based applications, including:

Triple play

Business connectivity (enterprise and SMB)

3G (Rel. 5) Ethernet-based mobile aggregation

DSLAM transport and aggregation

These services are offered over MPLS, Ethernet, or a combination of both.

Figure 1-5: Variety of Ethernet services



The range of data-centric services defined by the MEF standards includes:

Ethernet Line (E-Line) for P2P connectivity, used to create Ethernet private line services, Ethernet-based internet access services, and P2P Ethernet VPNs. These include: Ethernet Private Line (EPL): P2P Ethernet connection that uses

dedicated bandwidth, providing a fully managed, highly transparent transport service for Ethernet. EPL provides an extremely reliable and secure service, as would be expected from a private line.

Ethernet Virtual Private Line (EVPL): P2P connectivity over shared bandwidth. Service can be multiplexed at the user-to-network interface (UNI) level.

E-Line services may be implemented, for example, through an MPLS-based Virtual PseudoWire Service (VPWS). This implementation provides P2P connectivity over MPLS PW, sharing the same tunnel on the same locations and benefiting from MPLS E2E hard QoS (H-QoS) and carrier class capabilities.

Ethernet LAN (E-LAN) for multipoint-to-multipoint (MP2MP) (any-to-any) connectivity, designed for multipoint Ethernet VPNs and native Ethernet Transparent LAN Services (TLS). These include: Ethernet Private LAN (EPLAN): Multipoint connectivity over

dedicated bandwidth, where each subscriber site is connected to multiple sites using dedicated resources (so different customers' Ethernet frames are not multiplexed together).

Ethernet Virtual Private LAN (EVPLAN): Multipoint connectivity over shared bandwidth, where each subscriber site is connected to multiple sites using shared resources. This is a highly cost-effective service, as it can leverage shared transmission bandwidth in the network.

E-LAN services may be implemented, for example, through an MPLS-based VPLS. This implementation provides multipoint connectivity over MPLS PW, sharing the same tunnel, and enables delivery of any-to-any connectivity that expands a business LAN across the WAN. VPLS enables SPs to expand their L2 VPN service offerings to enterprise customers. VPLS provides the operational cost benefits of Ethernet with the E2E QoS of MPLS.

Classic VPLS service creates a full mesh between all network nodes and, under certain circumstances, this may not be the most efficient use of network resources. With H-VPLS, full mesh is created only between hub nodes using Split Horizon Groups (SHGs). Spoke nodes are only connected to their hubs, without SHGs. This efficient approach improves MP2MP service scaling and allows less powerful devices such as access switches to be used as spoke nodes, since it removes the burden of unnecessary connections.



E-Tree (Rooted-Multipoint) for point-to-multipoint (P2MP) multicast tree connectivity, designed for BTV/IPTV services. These include: Ethernet Private Tree (EP-Tree): In its simplest form, an E-Tree

service type provides a single root for multiple leaf UNIs. Each leaf UNI only exchanges data with the root UNI. This service is useful and enables very efficient bandwidth use for BTV or IPTV applications, such as multicast/broadcast packet video. With this approach, different copies of the packet need to be sent only to roots that are not sharing the same branch of the tree.

Ethernet Virtual Private Tree (EVP-Tree): An EVP-Tree is an E-Tree service that provides rooted-multipoint connectivity across a shared infrastructure supporting statistical multiplexing and over-subscription. EVP-Tree is used for hub and spoke architectures in which multiple remote offices require access to a single headquarters, or multiple customers require access to an internet SP's point of presence (POP).

E-Tree services may be implemented, for example, through an MPLS Rooted-P2MP Multicast Tree that provides an MPLS drop-and-continue multicast tree on a shared P2MP multicast tree tunnel, supporting multiple Digital TV (DTV)/IPTV services as part of a full triple play solution. LightSoft provides full support for classic E-Tree functionality as of V9.

Figure 1-6: MEF definitions for Ethernet services

The XDM product line features three independent cardsets for Ethernet in mixed SDH/Ethernet networks: the Layer 1 Data I/O cards (DIOB and DIOM), the Layer 2 Ethernet Interface and Switching modules (EIS), and the MPLS Carrier Class Switch cards (MCS). The MCS cardset supports the full set of MEF services, including E2E QoS, C-VLAN translation, flow control, and Differentiated Services Code Point (DSCP) classification. These cards are described in detail in MPLS/Ethernet Data Solution (page 5-1).



Next Generation Optics Today Flexible, coarse, dense Wavelength Division Multiplexing and multidegree Reconfigurable Optical Add/Drop Multiplexing (WDM/ROADM) networks, based on directionless, colorless, and contentionless ROADM technology, are an essential element of next generation (NG) transport networks, chosen by operators who are motivated by triple play delivery and business data connectivity demands. These bandwidth demands require the capacity, resilience, and outstanding flexibility of directionless, colorless, and contentionless multidegree ROADM as part of an all-range optical network that offers user-friendly service management and E2E route selection.

The XDM's field-proven 10-degree MEMS-Wavelength Selective Switch (WSS) ROADM technology, together with multirate combiners and transponders, multiprotocol Add/Drop Multiplexer (ADM) on a Card (AoC), fully tunable lasers, and modular card designs, introduces true flexibility to the network by providing any wavelength to any node ("any-to-any") connectivity in any ring or mesh topology. With no need to predefine traffic demands, remote service provisioning is fast and simple, requiring no re-engineering or manual tuning adjustments for both native and foreign wavelengths.



The unique state-of-the-art architecture of the XDM enables it to cost-effectively address metro, regional, and long-haul WDM requirements. A single product line provides complete, fully transparent E2E management over a multi-layered transport network. Sophisticated protection and restoration mechanisms are available. The XDM also offers a rich set of Optical Transport Network (OTN) features and benefits, including OTN framing with enhanced Forward Error Correction (FEC) and OTN wavelength and payload performance management. Combiners have Optical Transport Hierarchy (OTH) sub-wavelength multiplexing, and OTN in-band management is supported in all transponders and combiners. The XDM extends the OTN technology layer from the core down to the metro and access, enabling operators to seamlessly manage their network wavelength services, end to end. XDM NG optics also offers a full set of features aimed at simplifying planning, installation, operation, and maintenance of WDM/ROADM networks.

Figure 1-7: xWDM interworking with OTN services access to core



XDM optical components offer a comprehensive range of next generation capabilities that are robust, innovative, and future-proof. ECI is an innovator in implementing Ethernet/MPLS over OTN, utilizing field-proven XDM platforms to enable smooth migration to packet-over-optics, with an all-range system that provides cost-efficient solutions for networks ranging from under 100 km to over 2000 km. XDM platforms are future-proof as well, offering state-of-the-art 40G and 100G (future) solutions that increase capacity while reducing complexity. With ECI, the optical networks you enjoy today are already paving the way to the networks of tomorrow.

Figure 1-8: ECI's 40G transponder/combiner solution



Multidegree 40/80-Channel ROADM Flexibility

Adding new channels and rerouting existing ones in a network based on Mux/DeMux and fixed OADM technology is complicated, labor-intensive, and often traffic affecting. Even a minor adjustment often requires invasive network re-engineering. The XDM's multidegree ROADM technology, together with fully tunable lasers and innovative modular card design, automatic power and dispersion control, and smart yet simple E2E service management, eliminates these limitations by providing any wavelength to any node connectivity in any ring or mesh topology. With the XDM, there is no need to predefine traffic demands and virtually unlimited capability to add or reroute wavelengths.

Figure 1-9: Multidegree development



One key advantage of using a 10-degree WSS ROADM is cost-effective scalability with no traffic interruptions. Each degree corresponds to a 'colorless' port that supports one or multiple wavelengths. For initial deployment, the ROADM may serve as a typical 2-degree OADM node. As the network grows, other ports are simply configured as multiwavelength degrees for new WDM rings or P2P connections. Upgrading from 2-degree hardware to 4, 8, or more ROADM degrees is actually more expensive and disruptive than using ECIs 10-degree ROADM from day one.

Figure 1-10: Multidegree scalability

When considering ROADM deployment, operators expect the following features:

Flexible wavelength assignment and reassignment, simplifying the planning process and eliminating the need to predict future traffic flow

Ability to create complex optical topologies, such as: Subtending CWDM and SDH ring closure Multi-ring DWDM hub Mixed mesh and ring topologies

CAPEX savings: Eliminating regeneration in both ring and hub nodes Eliminating power tilt in regional/long-haul networks, thereby extending

the distance between regeneration points Coarse and Dense WDM interworking eliminating back-to-back systems Reducing spare inventory with widely tunable laser transceivers

OPEX savings through fewer manual operations, such as: 'SDH-like' provisioning, making wavelength provisioning as simple and

quick as for an STM-1 Remote provisioning and reconfiguration Software-tunable components, such as widely tunable 10G and 40G

transceivers Enhanced automatic power balancing and channel equalization



The XDM 10-degree ROADM supports all these benefits and more. The following figure illustrates its 'any wavelengths to any port' flexibility. WSS technology enables multidegree applications with the ability to create subtending networks directly from the WSS.

Figure 1-11: Multidegree ROADM capabilities

The 2-degree ROADM is optimized for ring nodes and hub sites with a large number (40/80) of add/drop channels, such as central offices (COs) or edge sites. This ROADM is typically integrated with metro and/or regional amplifiers.



To enable flexible and cost-effective utilization of ROADM in both metro and regional/long-haul networks, the XDM features an innovative ROADM-optimized amplifier. This amplifier offers low noise, gain flatness, and high midstage access loss, accommodating a WSS ROADM and dispersion compensation with no budget penalty. In addition, it has a robust redundant East/West architecture with no single point of failure (SPoF). Functionally, it is comparable to a two-stage Erbium-Doped Fiber Amplifier (EDFA) with discrete amplifiers used in each direction for total redundancy.

Figure 1-12: Typical multidegree ROADM application



Maximized Capacity and Range The unique architecture of the XDM enables it to cost effectively address metro, regional, and long-haul WDM requirements. One product line is used in all deployments, providing complete E2E management over a multi-layered WDM network with complete transparency.

Two key aspects of a C/DWDM system are its capacity and range. The XDM is a single high capacity all-range WDM solution for short, medium, and long-haul routes. It is optimized for any capacity (8, 16, 32, 40, or 80 channels of 2.5 Gbps, 10 Gbps, or 40 Gbps each), and for any range (80 km to 2,000 km/50 miles to 1250 miles). For example:

Up to 350 km/215 miles (80 x 10 Gbps) single span, with OTU2 Enhanced FEC (EFEC), EDFA, and Raman amplifiers

Up to 2,000 km/1250 miles (80 x 10 Gbps) with OTU2 EFEC and double-stage variable-gain EDFAs

Up to 1,500 km/930 miles (80 x 40 Gbps) with OTU3e EFEC, return-to-zero (RZ) Differential Quadrature Phase Shift Keying (DQPSK) modulation, and double-stage variable-gain EDFAs

Figure 1-13: All-range WDM capabilities



The Promise of OTN The ITU-T defined a set of standards for OTNs, primarily under recommendation G.709. An OTN is defined through a set of characteristics that includes wavelength framing, FEC, digital multiplexing of 2.5 Gbps to 10 Gbps and to 40 Gbps, multidomain performance monitoring (PM), optical protection, in-band management, alarm correlation, and more. OTN provides many benefits to carriers, including:

Universal management layer for wavelengths, regardless of the underlying services offered (IP, Ethernet, SDH, etc.), simplifying operation

Extended reach via FEC and EFEC

Timing transparency for timing-sensitive applications, such as SDH services

High capacity in-band management, simplifying and reducing the cost of managing WDM networks

The XDM offers a rich set of OTN features and advantages, including:

OTN framing and FEC/EFEC used in all XDM transponders for 2.5 Gbps, 10 Gbps, and 40 Gbps, including a class-leading transponder for full-rate 10 GbE LAN to OTN 10 Gbps

OTN combiners that implement OTH multiplexing for timing transparency and wavelength interworking, with OTN PM

OTN in-band management (General Communications Channel (GCC) bytes) supported in all XDM transponders and combiners

Furthermore, while OTN development was originally focused on the core, the XDM extends this technology layer down to the metro and access, enabling carriers to seamlessly manage their network wavelength services end to end.

Figure 1-14: OTN as a universal transport layer, access to core



Ease of Installation and Operation One of the key benefits of XDM NG optics is a full set of features aimed at simplifying planning, installation, operation, and maintenance of WDM/ROADM networks, tasks that were previously considered fairly complex. XDM provides all the convenience of modular automated optics technology, including:

Comprehensive planning tool for bandwidth optimization, optical link design optimization and verification, shelf layout, and more.

Enhanced Automatic Power Control (EAPC) continuously ensuring network resiliency, automatically adjusting to changes in optical power induced by variations in span loss and/or in the number of active channels - ignoring fiber cuts and maintenance actions and providing comprehensive status and history information.

Online configuration tool that simplifies network installation and provides logical easy-to-comprehend information on network connectivity.

ROADM-enabled wavelength management suite included with LightSoft - XDM's NMS - for remote E2E lambda provisioning.

ASON-based automatic network element (NE), link, and topology discovery that further simplifies hardware installation and network connectivity.



Packet-OTS: For Today's Challenges and Tomorrow's Goals

Network operators everywhere are trying to convert their networks to a converged network model that supports existing revenue-generating TDM as well as carrier class Ethernet and IP through an integrated technology approach. The most cost-effective solution lies in new packet optical transport capabilities that simplify and modernize as they transition to NG all-packet networks. The converged platform is referred to as a Packet Optical Transport System (Packet-OTS). Due to its straightforward all-inclusive approach to the industrys imminent transition, Packet-OTS technology has the potential to take over the telecom market.

Traffic-over-transport networks have been demonstrating their preference for packet-based transmission. SPs face the challenge of decoupling the linear linkage between growing capacity needs and the accompanying infrastructure costs, all the while generating revenues. Common approaches offered by equipment vendors include the use of WDM ROADM to cope with increased capacity and shift to a packet-based infrastructure to handle the traffic in a more cost-effective way. At the same time, SPs must maintain their revenue-generating TDM-based services. They hesitate to build a new packet-based infrastructure that will take over their well-proven and trusted SDH-based infrastructure.

ECI's revolutionary approach enables the best of all worlds - native Ethernet and SDH based on an optical infrastructure. The XDM family offers a series of Packet-OTS platforms providing an intelligent balance of technological flexibility and power. The ability of the XDM family to deliver different types of services over a variety of physical and technological media makes it the optimal solution for a mixed TDM/Ethernet environment and a cost-effective platform for the current era of transition. Even optimists forecast that transition to a packet-based transport network will take years to complete. Therefore, a solution that puts the SPs back in the driver's seat to control the pace is something they welcome.



Packet-OTS: Native to the XDM The XDM family introduced the concept of a unified transport layer that integrates SDH, Ethernet/MPLS, ATM, CWDM, and DWDM in a single platform. ECI pioneered the commercial introduction of convergence as an innovative approach to optical networking in 2001. Though this concept is now a trend with most optical network vendors, detailed market research shows that no other field-proven platform can actually be configured as a pure WDM/ROADM platform, SDH edge/core multiservice (with non-blocking switching capacities of 30 Gbps, 60 Gbps, 120 Gbps, or 240 Gbps), Carrier Ethernet, or a converged packet optical blend.

The XDM is a true converged packet optical platform with built-in Ethernet Layer 1, Ethernet Layer 2, SDH multiservice transport, and multidegree ROADM optical capabilities. As a simple example, the XDM can add/drop any E1 to/from any STM-16/STM-64 wavelength on the same shelf. Colored OTN interfaces are available for both TDM and Ethernet interfaces. With physical interfaces ranging from 40G to electrical E1, the XDM lowers both CAPEX and OPEX.

The XDM is optimally positioned to support the full cycle of network migration, enabling networks to gradually evolve from pure TDM to a mix of TDM and Ethernet to a pure packet-based network, while maintaining native handling of both TDM and Ethernet.

With its XDM family of products, ECI offers SPs a converged solution that combines NG-SDH, connection-oriented L2 MPLS Ethernet, and WDM/OTN ROADM - all in a single platform. Full OTN compliance provides protocol transparency, reduced costs, and interoperability on the optical level. By providing all of these features on a single platform, ECIs XDM meets the most stringent Packet-OTS definition.

The XDM feature set targets the evolution towards datacentric networks, and supports E-Line, EVPL, and MPLS-based VPLS/VPWS services from access to core, featuring a winning E2E service management approach that offers a combination of packet efficiency and SDH transport quality. As Ethernet customers and portions of the network start to migrate towards higher capacity, the underlying network infrastructure must expand as well. Some of the Ethernet services are thus provided directly over an optical infrastructure. The XDM provides the ideal interconnectivity for these services, whether Ethernet-, SDH-, or WDM/OTN-based.

Key Packet-Optical Convergence Benefits New revenue opportunities as well as cost savings abound for operators adopting Packet-OTS equipment, migrating to new services on a single platform using the same infrastructure. Packet-OTS equipment provides full carrier class E2E differentiated services with statistical multiplexing and high quality traditional services, together with WDM, OTN, and WSS ROADMs to support flexible optical meshes.

The optimal network architecture meeting the demands of today's customer is a convergence of packet and optical capabilities. SPs can retain the benefits and robustness of SDH while enjoying the advantages of Carrier Ethernet through the use of MPLS-TP and the high capacity, resilience, and flexibility of multidegree ROADM. They can continue selling their current TDM and HSI services and gradually add the triple play services of VoIP, IPTV, and VoD. They also have the ability to add any other Ethernet-based services for business (Virtual Private LAN Service or VPLS), 3G/4G Ethernet-based mobile aggregation, wholesale services, and more, in a single unified network.

The key benefits of a single converged network include:

Cost-optimized solution: Future-proof infrastructure with incremental CAPEX/OPEX, gradually adding packet-based services while supporting current TDM services.

Fast time to market (TTM): Adding any service to the existing infrastructure.

Revenue generation: From new services together with any other Ethernet-based services (LAN over the metro using VPLS, 3G mobile services, wholesale bandwidth services, etc.).

E2E service delivery: With MPLS-TP access aggregation to IP/MPLS core routers, ensuring the appropriate QoS for each service type with MPLS carrier class networking capability.

Single unified managed network: With the ability to provision any service E2E, including wavelength, TDM, and packet/Ethernet-based services.

Agile networking capabilities: Enable a quick response to new and unexpected traffic demands.

Risk minimization: Through an evolving metro aggregation network, rather than forklift changes to the network with the inherent high risks. New technologies are implemented without risking network reliability.
