The rapid growth of the Internet and Internet-enabled applications has led to a rapid increase in the scale and scope of the bandwidth required in service provider networks. Gigabit Ethernet has emerged as a crucial technology for enabling high-speed, low-cost network connectivity in the service provider's network for both inter-POP and intra-POP traffic. However, in addition to the scalable bandwidth connectivity provided by Gigabit Ethernet, the Service Provider's network also needs to perform high-touch IP services that enable and enforce tiered levels of provisioned bandwidth to meet the needs of a diverse customer base. Network services such as quality of service (QoS), security, traffic shaping, and traffic accounting have become mandatory requirements that must be integrated with high-speed Gigabit Ethernet connectivity to deliver the network capabilities necessary to ensure the Service Providers success.To meet these requirements, Cisco Systems now offers a four-port Gigabit Ethernet Optical Services Module (OSM) for the 7600 Internet Router to enable IP service delivery in service provider networks. This module uniquely allows service providers to increase network bandwidth and performance while offering a wide range of IP services. Service providers can deploy this solution in various tiers of a network architecture, allowing network performance and IP service delivery to scale linearly along with customer base growth. Furthermore, the IP services allow for peerless customer intimacy, with services such as QoS, security, traffic shaping, and billing offered not only on a per-customer basis. And the services scale for simultaneous IP service application to thousands of individual customers.
