摘要
为达到线速处理,要求路由器线卡的并行流量处理速度不小于所有接口速率之和.在接口密度和链路速率急剧上升的背景下,线速处理的实现代价非常昂贵.通过研究,对基于最坏条件的设计方法进行调整,根据并行处理模型,将网络流量的实际特性引入线卡设计,从而有效地降低了高密度线卡中并行流量处理的需求.同时讨论了新方法面临的工程实现问题和相关代价.
To satisfy this requirement＇, the traffic proeessing speed of the lineeard should be not less than the sum of the individual link rates. With the quick increasing of link rate, the line speed processing requirement becomes too hard in high-density linecard design. Based on the parallel processing model, this paper proposes a series of methods to help the community to change the design methodology from worst case oriented to real world traffic oriented. Thus it lowers the requirement of line-speed processing significantly. Performance cost and engineering questions involved in the implementing of this method are also covered.
