New Services on MSTP and Their Applications

The Metropolitan Area Network (MAN) is evolving from pure transport network to service network, which requires the support of new transport platforms. This paper analyzes the principles of how the SDH-based Multi-Service Transport Platform (MSTP) provides new services, and describes the service applications. It is noted that the MSTP, while combining Virtual Concatenation (VC), Link Capacity Adjustment Scheme (LCAS), Generic Framing Procedure (GFP) and other relevant technologies, can implement multi-service integrated access and convergence. MSTP can be embedded with Resilient Packet Ring (RPR) and MPLS technologies, thus supporting new services such as Virtue Private Network (VPN) and Bandwidth-on-Demand (BoD), and future 3G services.
