The Cisco ® IP NGN Carrier Ethernet Design Transform Consumer and Business Services… The IP NGN Carrier Ethernet design (Figure 3) uses key elements of the Cisco IP NGN architecture to enable a best-in-class implementation for Carrier Ethernet. It is the end-to-end transport layer from access, to edge aggregation, to intelligent services edge, to the IP/MPLS core. This design incorporates the Service Exchange Framework (SEF) network layer components and provides a flexible, scalable, and reliable network model to meet current and future network service requirements. One of the key principles of the Cisco IP NGN Carrier Ethernet design is that multiple Layer 2-3 network technologies are used to provide optimal flexibility for current and next-generation service offerings. These technologies and protocols include native Ethernet Virtual LAN (IEEE 802.1q), IEEE 802.1ad, Ethernet over MPLS (EoMPLS), Layer 3 Protocol Independent Multicast (PIM) with Source Specific Multicast (SSM), MPLS VPN, and Hierarchical Virtual Private LAN Service (H-VPLS). This allows service providers to support a broad range of applications while minimizing the capital and operating expenses associated with the network infrastructure. The IP NGN Carrier Ethernet design is the most scalable approach to delivering residential IPTV because it uses standards-based IP multicast (PIM) to deliver broadcast video to the edge of the network. This Layer 3 PIM-SSM to the edge design optimizes network bandwidth, and is more reliable than alternative H-VPLS broadcast approaches, which have suboptimal routing and bandwidth inefficiencies. In addition, PIM is the only multicast protocol that has been proven to operate reliably on a large scale, and in particular, Cisco’s PIM implementation has been optimized for IPTV and provides the fast routing convergence and rapid channel change capabilities expected by business and consumer video service subscribers.

With Flexible and Scalable Provisioning… The IP NGN Carrier Ethernet design provides a platform-independent architecture as well as a common command-line interface (CLI) and Ethernet-based services model across all Carrier Ethernet platforms. This allows for increased service flexibility and scalability across the network whereby multiple point-to-point and multipoint Layer 2-3 service types can be provisioned over the same physical port. Because VLANs have only port significance, scaling the number of service instances beyond the traditional 4000 limit on a device or network is no longer a problem. This new flexible provisioning also gives service providers a variety of VLAN translation mappings that help to uniquely track and scale services for their customers. Scalability of the aggregation network is augmented by new 20 Gigabit line cards that support enhanced queuing, high availability, and Hierarchical Quality of Service (HQoS) functionality. … combined with Standards-Based OAM The IP NGN Carrier Ethernet design also achieves carrier-class resiliency and troubleshooting requirements. Standards-based OAM end-to-end across the access, aggregation, and distribution components allow service providers to manage Ethernet connectivity all the way to the customer premises. This includes IEEE 802.1ag for service verification, IEEE 802.3ah for link-layer troubleshooting, and MEF E-LMI for service status and auto provisioning of customer equipment. Cisco is unique in its ability to deliver Ethernet OAM all the way to the customer premises and to link the access CPE to the intelligent Carrier Ethernet infrastructure. The IP NGN Carrier Ethernet Design is a highly available solution that supports sub-second multicast convergence and link restoration across the end-to-end network. Using Fast Reroute (FRR) for the aggregation and distribution EoMPLS tunnels, 50 millisecond (ms) restoration can be achieved for link restoration. In the event of a node failure, recovery will also occur in less than one second. Overall, the Cisco IP NGN Carrier Ethernet design leads the industry in both scalability and resilience. Figure 3.
