The Design, Performance Analysis and Implementation of VCAT in Backbone Networks for Software Radio System
Software Radio is a promising technology in today and futures communication systems. It exploits the advances of the high-speed digital signal processors and field programmable gate arrays to make the hardware generic, and moves all of the waveform-specific tasks into software. However, the data for transmission or received of the transmitter and the receiver should be shared in the local area networks (LAN) to form data centers and further wide area networks (WAN). While Multi-Service Transport Platform (MSTP) is a dominating in accessing todays backbone networks, which provides various ways for software radio terminators sharing their resources, such as Ethernet, E1/T1, etc. One of the key technologies of MSTP is the Virtual concatenation (VCAT), which provides more flexibility to Network Management System (NMS) compared with contiguous concatenation, and as a result, improves the network efficiency greatly. In this paper, we introduce our design and implementation of VCAT module for a MSTP ASIC. The procedure of theoretical analysis to determine several important performance related parameters is also discussed in detail. The overall design has been thoroughly simulated and verified through our self-made FPGA board, and has been successfully applied in our MSTP ASICs. We believe our work is significant for future developments of the software radio technology.
