The rapid growth of Internet-enabled user applications has led to a dramatic growth in the bandwidth provisioned through service provider
networks. In order to accommodate this growth, service providers are consolidating their various existing network architectures that
deliver traditional Layer-2 WAN transport, such as Frame Relay and ATM, with those that deliver Layer-3 WAN services, such as high
speed Internet access and Layer-3 VPNs. The consolidation of these network architectures optimizes the service providers capital
investments, so that all such expenditures simultaneously benefits all network services.
Achieving the convergence of these network architectures is particularly challenging at the network aggregation points that must deliver a
variety of services. The devices at these network aggregation points must be capable of providing an efficient transfer of network traffic
from the customer access nodes to the core network and back. Therefore, these aggregation devices must provide scalable bandwidth and
interface density between the access and core networks, while simultaneously supporting a wide range of network protocols, as well as
quality of service (QoS), security, and accounting features.
The Cisco 7600 is designed to provide the performance, density, and features that are needed for network aggregation devices in such
consolidated network architectures. The Cisco 7600 is a high performance aggregation router, which integrates high speed LAN and WAN
modules, and is specifically intended for service provider networks.
The two port OC12c/STM-4c ATM Optical Services Module expands the connectivity options for the Cisco 7600 Series Routers and
Cisco Catalyst 6500 Series Switches. The cards are ideal for aggregating large enterprise virtual channels and connecting them to
an existing ATM infrastructure.
