随着网上业务种类、业务量、用户数的迅猛发展,原有路由器在很多方面已经不能满足现在通信的需要,市场呼唤高速高性能路由器的出场。为了跟上 Internet时代的脚步,通信运营公司不断追求通过 IP、WDM、SONET、ATM 等技术构筑新一代的超高速网络.高速高性能路由器是下一代高速网络的核心.自1997年第一个吉比特级的路由器面世以来,高速高性能路由器迅速成为倍受瞩目的热点。下面是高速路由器主要技术发展特点综述。硬件革命推动高速路由器发展路由器的基本结构包括背板、转发判断、输出链路调度、转发路由表管理等几部分,其核心是背板设备。
With the rapid development of online business types, traffic volume and number of users, the existing routers can not meet the needs of current communications in many aspects. The market calls for the appearance of high-speed and high-performance routers. In order to keep abreast of the Internet era, telecom operators are constantly seeking to build a new generation of high-speed networks through technologies such as IP, WDM, SONET and ATM, etc. High-speed and high-performance routers are the core of next-generation high-speed networks. Since the advent of bit-level routers, high-speed and high-performance routers have quickly become a hot spot for attention. The following is a summary of the main features of high-speed router technology development. The hardware revolution drives the development of high-speed routers The basic structure of a router includes backplane, forwarding judgment, output link scheduling and forwarding routing table management. The core of the router is the backplane equipment.
