Multiservice Provisioning Platforms (MSPPs)

A Multiservice Provisioning Platform (MSPP) is an edge/aggregation platform that converges multiple services onto a SONET/SDH transport network. A typical system is chassis-based (except for Micro-MSPPs which are generally 1U or 2U platforms) and supports anywhere from six to twenty interface cards. The interface cards are interconnected through redundant cross connect cards that typically have a high-order (STS-N) and low-order (VT1.5) fabrics. Interface cards typically supported include the following:

The Ethernet interface cards enable service providers to integrate Ethernet packets into the exiting SONET/SDH infrastructure, thereby allowing data and Time Division Multiplexing (TDM) traffic to share the same transport mechanism. Many of these Ethernet interface cards are being re-architected to deliver new carrier Ethernet point-to-point services. The Brooklyn-10 Carrier Ethernet Switch is an ideal solution for these projects because it:

Ethernet services such as Provider Bridging (PB), Provider Edge Bridging (PEB), Provider Backbone Bridging (PBB), Provider Backbone Bridging with Traffic Engineering (PBB-TE) and Virtual Private LAN Service (VPLS) are implemented using configurable pipelined processors in the Brooklyn-10. This architecture provides deterministic performance and considerable flexibility while eliminating the costly and time consuming programming of packet processing engines. The SPI4.2 interface seamlessly connects to a wide selection of SONET/SDH framers and provides 128VCGs enabling a granular distribution of traffic in an STS fabric.

By using the Brooklyn-10 on an MSPP Ethernet interface card, developers can quickly and cost effectively deploy solutions that deliver Metro Ethernet Forum (MEF) compliant E-Line and E-LAN services.
