Enhance Network Flexibility and Performance

Service points-of-presence (POPs) groom traffic from the metro network, switch packets at the edge when IP services are enabled, and perform backbone switching when POPs are interconnected. Service POPs are also hubs of high-value Internet services such as Web content, DNS servers for Internet service providers, VPN services, and other applications deployed on a range of flexible, scalable, high-performance IP routers.

Efficient STS and optical bandwidth management is also a key consideration for service POPs.

Cisco service POP solutions offer multiservice interfaces and switching, providing both operational speed and flexibility in this rapidly changing area of the network. Dense wavelength-division multiplexing (DWDM) support combines with SONET/SDH optical interfaces ranging up to 10 Gbps for efficient bandwidth management at the STS-1 level of granularity. To conserve valuable space, a single-bay POP solution can manage thousands of 2.5- and 10-Gbps circuits and their STS-1 payloads. These combined features enable the system to manage bandwidth in wavelength, OC-n, and STS-1 increments and their data equivalents.
