摘要:

随着互联网的快速发展,高速TCP在光突发交换网络的性能表现引起了人们的极大兴趣。在光突发交换网络的突发包的大小,突发包的组装时间和波长数对高速TCP的性能影响的研究上,人们仅限于单个高速TCP的性能研究。本文通过仿真,系统的研究了多个高速TCP在光突发交换网络的性能体现。我们研究发现,当突发包的大小和突发包组包时间在一定值域时,随着汇聚包的大小和时间的增加,高速TCP的吞吐量相应增加,当达到一定值时,吞吐量反而减少;而高速TCP的吞吐量都随着波长数量的增加而增加。

With the rapid development of Internet, people have strong interest in studying the performance of high speed TCP variants in optical burst switching networks. But they are only restricted in single high speed TCP’s performance research about the influence of the burst’s size, burst’s assembly time and wavelength numbers. This article systematically research many high speed TCP variants in optical burst switching through the simulation. We show that the high-speed TCP variants have better performance than regular TCP and the throughput has rapid increase when we increase burst’s size, assembly time and wavelength numbers of burst. When reaching at a value, we also find that the throughput decreases with increasing burst’s size and assembly time.
