A Packet Dispatching Scheme with Load Balancing Based on iSLIP for Satellite Onboard CIOQ Switches

摘要

Under the circumstance of high reliability demand in satellite onboard switches, an Iterative Round-Robin with SLIP (iSLIP) matching scheduling algorithm with load balancing suitable for Combined Input and Output Queuing (CIOQ) switch is presented in this paper. The implementation of load balancer improves the system reliability and the ability of recovery from failure. The iSLIP algorithm with the function of load balancing is used in a 16 x 16 CIOQ switch, and the whole switch fabric is implemented in a Xilinx xc7vx690t FPGA. Typical simulated results are given and analysized.
