The growth of packet networking and value-added applications has led to the need for the next generation of capacity and service scaling in service provider networks. Optical Service Modules (OSMs) and the FlexWAN module are examples of optical-speed interfaces for the Catalyst 6000 Family of Switches and Cisco 7600 Internet router, delivering sophisticated packet services that enable and enforce tiered levels of provisioned bandwidth to meet the needs of a diverse customer base — including features such as quality of service (QoS), traffic shaping, and traffic accounting that have become critical requirements.
