TCP/IP Acceleration Stack Based on Multi-core Platform

Abstract

Multi-core processor gradually becomes the new trend of processor technology. When Linux TCP/IP protocol stack running on multi-core processors, the processing efficiency is often difficult to meet the requirements. In order to deal with this problem, this paper proposes a TCP/IP acceleration protocol stack based on multi-core processors. In this method, we divide multi-core processor cores into two groups, one group running general-purpose Linux operating system, the other running real-time operation system with TCP/IP protocol acceleration processing. Multi-core TCP/IP stack can offload TCP/IP protocol processing to real-time system and operate the underlying hardware resources directly, which improve the efficiency of network processing. The experimental results show that multi-core TCP/IP can not only deliver a high network performance than Linux TCP/IP, but also consume less CPU resources.
