High-Density OC-48c/STM-16 Connectivity for Consolidated Service Provider POPs with Service Delivery over IP or MPLS Core Networks

The rapid growth of Internet-enabled user applications has led to an increase in the bandwidth provisioned through service provider networks. To accommodate this growth, service providers are consolidating existing network architectures that deliver traditional Layer 2 WAN services, such as Frame Relay and ATM, with architectures that deliver Layer 3 WAN services, such as high-speed Internet access and Layer 3 VPNs. This network consolidation enables service providers to optimize their capital investments so that all such expenditures simultaneously benefit all network services.

Achieving network consolidation is particularly challenging at network aggregation points. The devices at these points must be able to deliver multiple Layer 2 and Layer 3 services, while providing efficient transfer of network traffic from customer access nodes to the core network and back. These aggregation devices must simultaneously provide scalable bandwidth and interface density between the access and core networks; support numerous network protocols, as well as quality-of-service (QoS), security, and accounting features; and be compatible with the existing SONET infrastructure.

Cisco ® 7600 Series routers provide the performance, density, and features needed for network aggregation devices in consolidated network architectures. To provide aggregation services over an existing SONET infrastructure, Cisco Series routers can be configured to support various SONET interface cards, such as the Cisco 1-port OC-48c/STM-16 Packet over SONET (POS) enhanced optical services modules (OSMs). These enhanced OSMs deliver advanced IP and Multiprotocol Label Switching (MPLS) services based on the Cisco Parallel Express Forwarding (PXF) network processor. The 1-port OC-48c POS includes two PXF processors-one for transmit processes and the other for receive processes.

ENHANCED OC-48 POS OSM FEATURE SUMMARY

The Cisco 1-port OC-48c/STM-16 POS enhanced OSM provides the benefits listed in Table 1.

Table 1. Features and Benefits of the OC-48c/STM-16 POS Enhanced OSM.


Feature	Benefit
Software-upgradable feature sets using the Cisco PXF network processor	Greater flexibility to support new features through software upgrades, while delivering performance similar to application-specific integrated circuit (ASIC)-based designs
Throughput of up to 5.5 Mpps per PXF IP services processor	High performance to support line-rate OC-48/STM-16 bandwidth
Four ports of Gigabit Ethernet, in addition to the OC-48 SONET ports	Simultaneous WAN and LAN access to meet diverse applications
Direct memory access (DMA) memory of 256 MB per PXF network processor	Supports a minimum of 8000 QoS queues per PXF network processor
Support for a minimum of 511 and a maximum of 1023 virtual routing and forwarding (VRF) instances per chassis for MPLS Layer 3	Outstanding service density per chassis for support of MPLS VPN services for end customers
Support for enhanced QoS features, including Class-Based Weighted Fair Queuing (CBWFQ), Low-Latency Queuing (LLQ), and Weighted Random Early Detection (WRED)	Improved delivery of service-level agreements (SLAs) to end customers
Support for Layer 2 network services, including Frame Relay and ATM, transported over MPLS network architectures	Ability to deliver both Layer 2 services, such as Frame Relay, Ethernet, and ATM, and Layer 3 services, such as Internet access and 2547 VPNs, in a consolidated network architecture

INVESTMENT PROTECTION

The Cisco 7600 Series enables Cisco customers to take advantage of their existing investments in Cisco equipment. In addition to the enhanced OSMs, the Cisco 7600 Series can be configured with any combination of traditional Cisco Catalyst ® 6000 Series LAN interfaces, and can also be configured with Cisco 7500 and 7200 series WAN port adapters. As a result, the Cisco 7600 Series offers outstanding scalability, with WAN interfaces from DS-0 through OC-48/STM-16 and LAN interfaces from 10/100-Mbps Ethernet to Gigabit Ethernet and 10 Gigabit Ethernet.

DESIGNED FOR SERVICE PROVIDER ENVIRONMENTS

The Cisco 7600 Series is specifically designed to meet the high-availability requirements for service provider networks. Each Cisco 7600 Series router provides a Network Equipment Building Standards 3 (NEBS-3)-compliant chassis. Furthermore, the Cisco 7600 Series supports fully redundant route processing and forwarding configurations, with the ability to route using such core protocols as Border Gateway Protocol Version 4 (BGP4), Intermediate System-to-Intermediate System (IS-IS), and Open Shortest Path First (OSPF), as well as support for QoS and packet filtering. The Cisco 7600 Series supports a 720-Gbps switch fabric, providing high aggregate throughput, as well as high port density, enabling service providers to optimize space utilization in the central office. Table 2 shows the OC-48 port densities that can be supported by the Cisco 7600 Series router with the 1-port OC-48c/STM-16 enhanced OSM.
