作为骨干网的核心设备,路由器产品和技术的发展水平,在很大程度上代表了网络建设的水平和方向。随着用户数量和各种新业务的大幅度拓展,互联网上的数据流量激增,影响核心网络性能的瓶颈已不再是传输的带宽,而是转移到各交换转发的节点上。而且随着信息化和网络建设的发展,对于 As the key equipment of the backbone network, the level of development of router products and technologies largely represents the level and direction of network construction. As the number of users and the drastic expansion of various new services increase the data traffic on the Internet, the bottleneck affecting the performance of the core network is no longer the bandwidth of the transmission, but is transferred to the nodes that exchange and forward. And with the development of information technology and network construction,
