An Input-Buffer Scheduling Algorithm in Satellite Switching System

In order to improve satellite switching performance, a new scheduling algorithm is proposed. Based on Crossbar switch fabric，the algorithm adopts serial scheduling strategy and adjusts the output port arbitrating strategy for the better equity of every port. Consequently, it increases the matching probability. The algorithm can greatly reduced the scheduling delay and loss rate. The analysis and simulation results show that the proposed algorithm has the better performance than others in average delay and cell loss rate, and has the equivalent complexity.
