Packet Prediction for Speculative Cut-Through Switching
The amount of intelligent packet processing in an Ethernet switch continues to grow, in order to support of embedded applications such as network security, load balancing and quality of service assurance. This increased packet processing is contributing to greater per-packet latency through the switch. In addition, there is a growing interest in using Ethernet switches in low latency environments such as high-performance clusters, storage area networks and real-time media distribution. This paper proposes Packet Prediction for Speculative Cut-through Switching (PPSCS), a novel approach to reducing the latency of modern Ethernet switches without sacrificing feature rich policy based forwarding enabled by deep packet inspection.
