Abstract

Optical packet switching networks promise to provide high-speed data communication and serve as the foundation of the future Internet. A key technological problem is the very small size of packet buffers that can be implemented in the optical domain. Existing protocols, for example the transmission control protocol, do not perform well in such small-buffer networks. To address this problem, we have proposed techniques for actively pacing traffic to ensure that traffic bursts are reduced or eliminated and thus do not cause packet losses in routers with small buffers. In this paper, we present the design and prototype of a hardware implementation of a packet pacing system based on the NetFPGA system. Our results show that traffic pacing can be implemented with few hardware resources and without reducing system throughput. Therefore, we believe traffic pacing can be deployed widely to improve the operation of current and future networks.
高性能实现网内流量踱步
光分组交换网络有望提供高速数据通信,并作为未来互联网的基础。一个关键的技术问题是可以在光域实现的非常小的数据包缓冲区。现有的协议,例如传输控制协议,在这种小缓冲区网络中表现不佳。为了解决这个问题,我们提出了主动调整流量的技术,以确保减少或消除流量突发,从而不会在具有小缓冲区的路由器中造成数据包丢失。在本文中,我们提出了一个基于NetFPGA系统的数据包起搏系统的硬件实现的设计和原型。我们的研究结果表明,流量调整可以在不降低系统吞吐量的情况下,以很少的硬件资源实现。因此,我们相信流量调频可以广泛应用,以改善当前和未来网络的运作。
