Metro Ethernet Services Unit 1800 As service providers strive to generate revenues, the promise of Ethernet services is enticing. With the higher levels of band-width that can be supported at more granularservice rates, implementing Ethernet VPNservices across a shared infrastructure allowsservice providers to drive revenues while distributing costs across many more customers.Additionally, the operational simplicity thatEthernet affords simultaneously helps reduceongoing expenses.

What is still required is an element for the network edge that can economicallyprovide several key service attributes.These include: a point of demarcationbetween provider and customer; the rateenforcement, classification, and prioritiza-tion features to support differentiated service levels; and complete managementcapabilities that simplify network operations.

Metro Ethernet Services Unit 1800 benefits:

• As the delivery point for Ethernet services at the edge of the service provider

network, effectively supports Internet access, video transport, Virtual Private

LAN service, and other applications for multiple customers on one physical port

• Enables an Ethernet-over-dark-fiber access ring topology that achieves 50ms

recovery, supporting up to 14 units per ring to maximize bandwidth utilization

and network reliability

• Compact and cost-effective platform delivers multiple classes of service, prioriti-

zation, rate enforcement, and statistics collection features that are critical for

the delivery of profitable Ethernet VPN services and meeting Service Level

Agreements (SLAs)

• Integrated end-to-end VPN Continuity Check ensures service is up and

running at all times and that SLAs are met, while SNMP and Web-based

management simplify operations and reduce expenses

switched Ethernet-over-fiber infrastruc-ture. Additionally, the Metro EthernetServices Unit 1800 supports:

• Multiple services (e.g., Internet access, VPLS, VoIP, etc.) per physical interface for maximum revenue generation

• Multiple classes of services for priori-tization and traffic managementrequired to offer and meet strict SLAs

• End-to-end service managementincluding tools to support perfor-mance monitoring, service assurance,and SLA measurement

Ethernet Access Ring Resiliency ProtocolEthernet Access Ring Resiliency Protocoldelivers industry-leading reliability and highly efficient aggregation for anEthernet-over-fiber solution. With theability to be configured in an access ringtopology (supporting up to 14 MetroEthernet Services Unit 1800s per accessring), sub-50ms recovery can be achieved.

The Nortel Networks Metro EthernetService Module 8668 for the Passport8600 Routing Switch acts as the “head-end” node. In the event of a link ornode failure in the ring, traffic will bedirected to the alternate path and recoverin 50ms. This capability, previouslyavailable only in SONET or WDMimplementations, allows service providersto protect the most vulnerable part ofthe network with a cost-effective solution.

Enterprise customers are demandingflexible service rates, at intervals lowerthan the full rate of the interface (e.g.,25 Mbps on a 100 Mbps port). If theaccess infrastructure is constructed in apoint-to-point fashion, there is a greaterlikelihood that the Gigabit Ethernetuplink from the CLE device to the central office device will be severelyunder-utilized.

power supply

Additionally, the means to assure serviceintegrity and availability is necessaryfor service providers to build and sup-port strict SLAs, as with any other“service-oriented” technology.

Because so much of the service provider’scapital equipment investment is incurredat the edge—sometimes as much as 60percent or even greater—they needthese features delivered in a cost-effectiveplatform located at the customer premises.

Nortel Networks Metro Ethernet ServicesUnit 1800 is a fixed port Ethernet switchdesigned for use as Customer LocatedEquipment (CLE) at the edge of theservice provider network as part of anEthernet VPN service. The MetroEthernet Services Unit 1800 provides a compact and cost-effective solutionthat is easy to implement and use. Itdelivers wire-speed performance alongwith the rate enforcement, classification,QoS/prioritization, and statistics collection features that are critical forthe delivery of profitable Ethernet ser-vices. It also helps providers meet theSLAs required by their end customers.

Twenty-four 10/100 Ethernet cus-tomer facing ports and two GigabitEthernet network facing ports (SFPGBIC-based or fixed LX) combine to provide flexible Ethernet servicedelivery in a 1U-high solution. Thenon-blocking architecture provideswire-speed switching for uncompro-mising performance. Packet classifica-tion based on 802.1p and DiffServCode Points allows service providersto offer tiered services with QoS totheir end customers—profitably.

The Metro Ethernet Services Unit1800, in combination with the NortelMetro Ethernet Services Module 8668,allows service providers to deliver anEthernet access ring solution thatdelivers sub-50ms resiliency and highlyefficient bandwidth aggregation in a

ring capability enabled by the MetroEthernet Services Unit 1800 and theMetro Ethernet Services Module 8668provides an aggregation network thatefficiently utilizes the infrastructureinvestment.

Multiple services per UNI port Service providers today seek top linegrowth, and must maximize revenuegeneration. The ability to deliver more thanone service to a particular customer whileleveraging the same infrastructure helpsdo just that. For example, multiserviceoperators (MSOs) seek to deliver the“triple play”—voice, video, and data(example applications include VoIP traffic, video content distribution, and Internet access), all leveraging the samefiber plant.

The Nortel Networks solution allows service providers to deliver more than just Ethernet connectivity service overthe Metro Ethernet Services Unit 1800infrastructure. It enables providers tomove up the value chain to offer value-added services that enterprise customersare demanding. End customers canmaintain the VLAN schemes used intheir own networks, yet still access different services offered by the serviceprovider—all enabled by the sameEthernet interface of the MetroEthernet Services Unit 1800. Simplyput, service providers are able to leveragea lower-cost, shared network infrastruc-ture across multiple customers and offerconsistent services and SLAs.

Multiple Classes of Services

VoIP and video traffic are sensitive to both network delay and jitter—the variation experienced in that delay. The ability to classify traffic as early as possible helps ensure that mission-critical applications are given the levelof performance dictated by their servicecontracts on an end-to-end basis.

By assigning different service class levelsto traffic flows, applications can be giventhe bandwidth and network priorityrequired where and when they need it.

The Metro Ethernet Services Unit1800’s wire-speed, non-blocking archi-tecture provides the performance andQoS features to support the require-ments of delay-sensitive applications.Four priority egress queues form thebasis of Metro Ethernet Services Unit1800 traffic management functionality.With the ability to classify traffic basedon IEEE 802.1Q/p and DiffServ mark-ings and prioritize accordingly, delay-sensitive applications can be given priority across the access ring.

Service continuity and management

The Metro Ethernet Services Unit 1800,coupled with the Metro EthernetServices Module 8668, provides a com-plete set of tools for service assuranceand SLA measurement as well as perfor-mance monitoring and troubleshooting.

A key differentiator of Nortel NetworksEthernet VPN management solution,VPN Continuity Check, is a powerfulservice assurance and debugging tool critical to measuring and validating customers’ SLAs. It may be used to validate all VPN end-points, test connectivity, and determine round-trip delay measurements per VPN. The tool may be invoked from the network operations center using thecommand line interface or from NortelNetworks Preside Site Manager, thusremoving the need for costly customersite trips.
