As digital devices with communication capability become more pervasive, the network performance of a corresponding server needs to be improved. In this paper, we present the hardware and software for offloading the socket processing in order to improve the network performance of a server. The experimental results showed that the proposed solution could improve the network performance of a typical solution significantly. Furthermore, the proposed solution can provide the binary compatibility with the BSD socket standard such that the existing network programs can be used without modification and/or recompilation.

Keywords: ubiquitous/home-network service, network I/O, TCP/IP, TOE, socket offloading
