| Abstract(in English) | Most of the researches have been concentrated on how to avoid and dissolve the network congestion, and only a few discussions on the performance improvement of the endhosts are recently made. In this paper, we focus on data transfer using TCP and analyze the details of TCP data transfer at the endhost. Through the analysis, we have found that memory access is the largest obstacle for performance improvement in TCP data transfer. Then we propose a new mechanism which reduces the number of memory access in TCP data transfer, and compose some of new socket system calls to avoid the redundant memory copy process. We further implement the proposed mechanism to the actual computers running FreeBSD, and show that the proposed mechanism can improve 30-50% of the transfer speed compared with the original mechanism through some experiments. |
