TCP/IP Offload Engine Module Supporting Binary Compatibility for Standard Socket Interfaces

摘要

TCP/IP is the most commonly used protocol to communicate among servers, especially, it is used in a wide range of applications in GRID evironment. Unfortunately, Data transmission through TCP/IP places a very heavy burden on host CPUs. And it hardly makes another job to be processed. So, TOE(TCP/IP Offload Engine) is considered in many servers. But, most of TOE modules tend to not support binary compatibility for standard socket interfaces. So, it has problems that existing applications should be modified and recompiled to get advantage of TOE device. In this paper, to resolve upper problems, we suppose design and implementation of TOE module supporting binary compatibility for standard socket interfaces. Also, it can make a usage of multiple TOEs and NICs simultaneously.
