千兆以太网通道化技术的研究

Research on 1000Mbps Ethernet Channelized Technology

为了能够在同一个千兆以太网线路上给多个用户提供类似专用线路的网络效果,此文研究了在1000 M以太网线路上把同一个物理通道分为多个逻辑通道进行数据传输,从而达到多个私有网络通过同一线路进行传输的问题,文中首先提出了使用硬件限流实现通道化的方法,然后做了实验板进行并用专用测试仪进行测试验证,试验结果表明,该技术能够达到对千兆以太网通道化的目的,处理能力能够达到线速,而且协议简单,带宽利用率较高。

The division of one physical channel into multiple logistic channels is researched. Thus multiple private networks could achieve transmissions on the same line. This paper proposes first the implementation of channelization technology by flow control. Then with special tester the experiment and test is done on testing PCB. The result indicates that this technology could meet the channelization requirement, and the processing ability could be up to the speed of the line. This technology is simple in protocol and efficient in bandwidth utilization.
