Abstract:Fuzzy control variable weight method of multi-factor decision-making adaptive deficit round robin scheduling algorithm (VWADRR), an improved deficit round robin(DRR) scheduling algorithm is put forward. It’s used in the circumstance of scheduling multiple multi-media data streams. It bases on multi-factor decision-making in the fuzzy control theory, specific to the use of the variable weight method. It’s adaptive for output channel bandwidth and buffer size of each input queues. Variable weight method makes decisions based on these two factors, that is, to determine the QN as variable in DRR. Considering the time of each packet sent, it reduces the packet delay. It effective uses buffers and bandwidth in the heavy network traffic situation, significantly reduces the possibility of buffer depletion, also smoothes burst.
