Abstract
Streaming media packet processing is a typical streaming application, which is very sensitive in delay and delay jitter. Multi-core network processor has carried on the special optimization for high-speed network processing with advantages of flexible and efficient. FCFS scheduling algorithm can achieve load balance on packet, but can hardly reach cache affinity. The scheduling algorithm based on hash can guarantee cache affinity, but difficult to balance the load between processing cores. According to the characteristics of streaming media and the deficiency of existing packet scheduling algorithm, this paper proposes a two-level scheduling scheme based on multi-core processor -- MC-SPS. The simulation evaluation show that MC-SPS algorithm has better load balancing and cache affinity, can improve the media processing performance.
