在自治系统内部的各个路由器之间,运行的是内部网关协议IGP。早期的IGP叫做 (1) ,它执行 (2) 。当网络规模扩大时,该算法使得传送的路由信息太多,增加了网络负载,后来又出现了执行最短路径优先算法的IGP。按照这种协议,每个路由器向网络中的其他路由器发布 (3) ,当路由信息改变后,路由器按照 (4) 算法更新路由表。在不同自治系统的路由器之间,运行外部网关协议EGP,典型的EGP是 (5) 。 4()

Frame Relay is simplified form of (1) , similar in principle to (2) , in which synchronous, frames of data are routed to different destinations depending on header information.Packets are routed throught one or more Virtual Circuits known as (3) Most Virtual Circuits are (4) , which means that the network provider sets up all DLCI connections at subscription time. (5) are also part of the Frame Relay specification. They privide a link that only lasts only as long as the session. 5()
