摘　　要：1引言 传统的以太网架构,虽然已经被改进和增强以满足数据中心、高性能服务器的需要,但是由于它本身的带宽限制以及TCP/IP协议的高复杂性,产生带宽瓶颈,消耗服务器的大量CPU和内存资源.这样不仅服务器的带宽成为瓶颈,而且服务器的相当一部分资源被消耗在网络I/O处理而不是应用处理上,并使得它很难扩展[1].InfiniBand (IB) is a high speed, channel based interconnecting technology between systems and devices. It will remove the bottleneck limiting the performance of current servers and storage divices. This article proposes an IP over InfiniBand (IPoIB) architecture and its application. It will function as a bridge between IP and IB architecture in systems IP and IB coexists. It enables the applications to take advantages of IB without changes in upper layers IP and other protocols. We also introduce the IPoIB protocol and show some experiment results in this paper. The experiment results show that IPoIB is suitable to be used in the front-end servers and interface devices for the InfiniBand. based network servers.
