Role of The is a flexible component of the IETF s MPLS-based VPN model for metro networks. It delivers intelligence as a provider edge device (PE), or a customer edge device (CE).

The LPE distributes the tasks of the PE over two logical network elements: the PE-Core and PE-Edge.

In this role, it serves as the demarcation point between the core/backbone network and the PE-Edge.

It interoperates with other Layer 2 VPN PE devices and distributes service labels and transport tunnel information to the core and local Layer 2 network.

2 Role of The is a flexible component of the IETF s MPLS-based VPN model for metro networks. It delivers intelligence as a provider edge device (PE), or a customer edge device (CE). The Nortel Networks Optical Ethernet takes the IETF model one step further by introducing the logical provider edge (LPE). The LPE distributes the tasks of the PE over two logical network elements: the PE-Core and PE-Edge. This functional distribution enables significantly greater scale, simplified provisioning and operation, and greater reliability. is primarily designed to operate as a PE-Core device. In this role, it serves as the demarcation point between the core/backbone network and the PE-Edge. It enables automatic discovery, label distribution (LDP), Draft Martini MPLS encapsulation, as well as MPLS traffic engineering, protection, and recovery. It interoperates with other Layer 2 VPN PE devices and distributes service labels and transport tunnel information to the core and local Layer 2 network. In addition to distributing membership schemes, the PE-Core handles edge-to-core VPN information exchange protocols. A PE-Edge device, such as the OPTera Metro 1200 Ethernet Services Module, makes Ethernet UNIs available to customers for termination of Layer 2 VPNs. In addition to managing VPN membership labels and ingress/egress traffic, the PE-Edge performs automatic discovery for routes and services in the Layer 2 domain. Network architecture connects to multiple PE and/or LPE devices across the Optical Ethernet service network and to an MPLS backbone. It also supports direct connection to a customer edge device to provide the same Ethernet UNI functionality, which may be applicable for large installations. In addition to supporting MPLS LER functionality and managing traffic engineered transport tunnels, OPTera Metro 8000 maps customer data (e.g., VLAN information) to the appropriate MPLS path for transport across the core. Implementing MPLS at Layer 2 eliminates the need for Spanning Tree Protocol (STP) and replaces it with a more reliable, traffic engineered MPLS network.

Features and benefits Industry-leading intelligence The new Optical Services Module (OSM) for the brings MPLS VPN and traffic engineering capabilities to the provider edge using an array of programmable and field upgradeable network processors. This innovative network processingbased design delivers a potent combination of speed and flexibility without forklift upgrades. The with the OSM also provides MPLS LER functionality at the provider edge. This powerful combination supports extended Draft Martini Layer 2 VPNs, MPLS traffic engineering (RSVP-TE), label distribution protocol (LDP), and VPN SLAs for tunable bandwidth over label switch paths (LSPs). These innovations provide dramatic improvements in the following areas. Connectivity The complex provisioning arising from full meshes of point-to-point metro links (commonly referred to as the N 2 problem) is dramatically simplified by the ability to classify and connect logical interfaces to core VLANs using MAC addresses. Functional distribution and encapsulation By enabling VPN classification at the provider edge and interoperating with RFC 2547 MPLS in the core, OPTera Metro 8000 offloads expensive core routers, which reduces capital equipment costs while enabling SLA enforcement.

4 Simple End Point Provisioning In contrast to the complex and costly provisioning process associated with fully meshed metro networks, OPTera Metro 8000 enables any-to-any autodiscovery, thus significantly reducing provisioning time and operational costs and speeding time-to-revenue. Traffic engineering Leveraging standard RSVP-TE, uses bandwidth more efficiently and supports a single metro infrastructure for Layer 2 VPN, Layer 3 VPN, and IP traffic so that providers can offer a wide range of Layer 2 and Layer 3 services to targeted markets. Bandwidth flexibility and smart tools Combining Ethernet bandwidth flexibility with the sophisticated traffic engineering tools of MPLS allows service providers using the OPTera Metro 8000 to take advantage of valuable features, including: Tunable bandwidth from 1M to 1000M in 1M increments without requiring additional network engineering or customer equipment Committed rate and allowable burst using traffic policing and shaping Robust QoS controls mapping a customer s priority information (802.P/Q) and supporting service levels, service type, and class of service Network transparency enabling end users to send and receive standard Ethernet packets without visibility to the underlying MPLSbased network and without changes to the enterprise addressing scheme. Massive bandwidth and performance At the network level, Optical Ethernet outperforms traditional metro networks by making more efficient use of bandwidth. The initial release of the MPLSenabled offers a best-in-class 64 Gbps at full-line rate with a maximum throughput of 128 Gbps and provides a roadmap to higher speeds in the future. It also provides 96M packets per second, which is three times the speed available from its nearest competitor. In addition, the 4-port MPLS module ranks as best-in-class for port density, with an 8-port version planned for future release. The switching architecture distributes processing tasks, eliminating bottlenecks that frequently occur with systems based on centralized processing. Dual load-sharing, upgradeable switch fabric/cpu modules house the product s central intelligence, including master forwarding tables, management, and the file system. Silicon hardware at the port level makes packet classification and routing decisions, resulting in faster processing than the software-based filtering used by legacy routers. Layer 2-3 hardware-based filtering for security and traffic classification enables networks based on to maintain QoS profiles and differentiated treatment from end-to-end. Eight hardware-based queues allow network managers to offer service levels based on applications and other criteria. The also blasts through metro bandwidth bottlenecks for Layer 1 services with guaranteed bit rate lambdas and support for the WDM-based Optical Ethernet Wavelength System. Unsurpassed reliability The provides carrier-grade reliability at the network level and offers protection strategies at the trunk and device levels. At the network level, the OPTera Metro 8000 achieves reliability and redundancy in several ways. For instance, its MPLS capabilities enable multisite redundancy and failover. The VRRP feature routes around disabled network devices and does not require router discovery protocols on every end host. The ECMP capability supports load-sharing across multiple equal-cost routed paths and allows rapid convergence to an alternative path if necessary. At the trunk level, the DMLT feature provides redundancy by enabling trunk groups to be configured across different slots in the same chassis. This strategy keeps links active in the event of a module failure. At the device level, is the only product in the industry capable of being configured as entirely redundant eliminating it as a potential single point of failure. This system is equipped with redundant, hot-swappable components (i.e., switch fabrics, I/O modules, power supplies, fan trays). Temperature sensors constantly monitor components and cooling systems. The NEBS-compliant chassis meets rigorous electrical, environmental, temperature, and vibration standards.
