A-2100 Carrier Ethernet Edge Switch

Nokia Siemens Networks’ A-2100 Carrier Ethernet Edge Switch hasbeen developed specifically for delivering MEF-based E-Line, E-LAN or E-Tree services either as CPE in customer environments or as an aggregator in Central Offices, Carrier Point of Presence and CollocationCages with stringent environmental requirements. It is designed with acompact and ETSI-compliant size to save rack space, equipped with either AC or DC power and a rich set of hot-swappable interface cards.

In addition to Ethernet services and triple-play services, withNokia Siemens Networks’ industry-leading Circuit EmulationService support, the A-2100 can help service providers migrateTDM-based traffic seamlessly over a high-performance, costeffective Carrier Ethernet network.

With the rapid increase in the need forhigh bandwidth, and the equally im-pressive increase in the performanceof Ethernet within the LAN environ-ment, the demand for metro networkperformance has never been greater.

Features

• Multi-service enabled, including E-Line,E-LAN, E-Tree, CES, and triple-playservices, on a single device

• Support for Hard QoS such as CIR,EIR and Priority

• Support for 50ms carrier-class protection without using Spanning Tree Protocol

• High performance and very low delayand jitter

• Strong and comprehensive OAM functions such as Ethernet Loopbacksand per-connection SLA measurement

• Compact and ETSI-compliant size with just 1U height

The biggest challenge for serviceproviders of all types is to deliver not only cost-effective and scalable performance, but also, and more importantly, a Carrier Ethernet solutionthat facilitates new services, rapid andeasy provisioning, and dramatically reduced operational costs.

A-Series Switches End-to-End Carrier Ethernet Solution

Product OverviewNokia Siemens Networks’ A-2100 is a one rack-unit high, compact CarrierEthernet Edge Switch that deliverscost-effective 10/100 Ethernet, GigabitEthernet or CES/TDM access inter-faces for end customers. All the accessmodules are hot swappable.

It has two Gigabit Ethernet SFP/SSF-pluggable ports for connectivity to theCarrier Ethernet core network. Redun-dant load-sharing AC and DC powerare also hot swappable.

The A-2100 can be deployed as ahigh-end CPE working with the NokiaSiemens Networks A-4000 and A-8000

series of Carrier Ethernet Core Switch-es and ASPEN management system.The A-2100 can also be used as anaggregation switch working together with the A-100 or A-1180 demarcation device to provide a verycost-effective access solution. Usingthese products in conjunction, carriersand service providers can construct apowerful Metro infrastructure with highperformance and efficiency, designedto quickly deliver profitable communi-cation services.

The A-2100 features 4Gbps non-blocking switching capacity. It offers up to 2,000 protected simultaneousconnections supporting point-to-point,point-to-multipoint and multipoint-to-multipoint services. Customer trafficcan be mapped to connections usingmultiple and flexible rules from layer 1(port-based) up to layer 3 (IP Address, Protocol Type and DSCP bits).

Functions

• Hard QoS supporting CIR,EIR and priority with 64Kbpsand 1Mbps granularity

• Call Admission Control(CAC), ensuring end-to-endbandwidth guarantee

• SONET-like 50ms protectionusing Fast Reroute protocolthat is much faster and morescalable than Spanning Treeor Rapid Spanning Tree protocol

• Strong and comprehensiveOAM functions including fastand pinpoint fault detection,alarm-service correlation,Ethernet loop-backs, as wellas round-trip delay, jitter andpacket loss measurement

• A full set of multicast features that support scalableand QoS guaranteed triple-play services

• Wire-speed performance

• Very low delay and jitter

• Flexible and intelligent customer traffic mappingmechanisms that allows multi-services on one accessinterface

• Up to 2,000 protected connections per device

• Strong management capability

Applications

Multi-service CPE with HighService Availability for BusinessCustomersThe A-2100 boasts a broad range ofintelligent network services, featuringgranular Quality of Service (QoS) andsub-50ms protection that enable serv-ice providers to rapidly provision se-cure Ethernet access with fully MEF-compliant Service Level Agreements(SLAs).• High revenues from multi-services• Fast trouble-shooting with the help

of strong OAM functions• Flexible customer traffic mapping

schemes• Support for single-strand fiber,

reducing fiber costs• Ease of management and service

provisioning

ETSI-compliant Multi-serviceAggregator in Central Office (CO)Suitable for CO and street cabinet deployment with ETSI compliance, the A-2100 can be used in the CO toaggregate multiple business customersand deliver flexible, affordable E-Line,E-LAN and multicast or E-Tree serv-ices as well as TDM services.• Rich set of interfaces with high port

density allows aggregating manycustomers of various types

• A complete solution working with A-100, A-1180 and A-210 demarca-tion devices, providing end-to-end management and OAM functions

• Single-strand fiber interfaces, reducing fiber cost

• Support for TDM grooming functions (T1/E1 to OC-3/STM-1),helping keep the existing TDM-based services unchanged whileproviding new Ethernet services

FTTH/FTTC Aggregator forTriple-Play ServicesThe A-2100 also delivers triple-playservices in FTTH/FTTC environments.It features all the standards-based multicast functions with full protectionagainst both network failure and videosource failure. Carriers and serviceproviders are able to build a single infrastructure to serve both businessand residential markets.• Connection-oriented multicast solu-

tion for IPTV that is more scalablethan IP-based multicast protocolsuch as PIM-SM

• Stringent QoS for guaranteed voice and video services

• 50ms protection against both net-work failure and video source failure

• Fast Channel Zapping and IGMPACL

• Support for Open Access BusinessModel

MEF-Compliant Service AttributesThe A-2100 delivers flexible, affordableFast Ethernet and Gigabit Ethernet access interfaces, supporting point-to-point, point-to-multipoint and multipoint-to-multipoint services. Customer trafficcan be mapped to connections usingany combination of rules from layer 1to layer 3.

The A-2100 fully supports Service Level Agreements defined by MEFservice definitions including:• Committed Information Rate (CIR)• Excess Information Rate (EIR)• Priority for bounded delay and jitter• Protection levels (sub-10sec or

sub-50ms)

In addition to pure Ethernet connectivity,service providers can migrate legacyTDM traffic onto their Carrier Ethernetnetwork using Circuit Emulation Services modules that provide ITU-Tcompliant E1/T1, E3/T3 and STM-1/OC-3 interfaces.

Full Protection and ReliabilityThe A-2100 has been designed to de-liver the SONET-like 50ms protectionand reliability that carriers demand, butwith the price, performance and scala-bility of Carrier Ethernet. Unlike otherproducts that base their protectionmechanism on Spanning Tree Proto-col, which leads to poor scalability,long and non-deterministic fail-overtime, the protection mechanism of theA-2100 is similar to MPLS FastReroute, and thus can achieve sub-50ms fail-over time. It also offers anend-to-end protection mechanism thatprotects against any types of failurewithin sub-10seconds, according toservice profiles.
