与传统光网络相比，光分组交换(OPS)网络具有高速、大吞吐量、低时延和能高效地承载IP业务等突出优点。而作为支撑下一代Internet发展的最有希望的骨干光网络，OPS网与传输控制协议/互联网协议(TCP/IP)的兼容性和支持度是一个值得深入研究的课题。文章以光突发交换(OBS)网为模型，对OPS网络中的TCP传输性能进行了研究。

Compared with the traditional optical networks, Optical Packet Switching (OPS) networks are characteristic of such outstanding advantages as high speed, large throughput, low latency and high efficiency in carrying IP services. As the most promising optical backbone network to support the development of the next-generation Internet, The compatibility with support to OPS and TCP/IP networks is a subject worth of in-depth study. Taking the Optical Burst Switching (OBS) network as a model, this paper studies the Transmission Control Protocol (TCP) performances in the OPS switching network.
