Recently, IEEE 802.16j multi-hop relay network is proposed to increase data rate and coverage of the IEEE 802.16e networks. The Relay Station (RS) is introduced to relay the data from MR-BS to SS/MS or from SS/MS to MR-RS. We have studied the researc

本章先讨论广域网基本概念，包括广域网所提供的两种服务——数据报和虚电路。接着要讨论分组转发，即网络交换结点怎样知道应通过哪条路径(path)才能将数据转发到所要通信的目的主机。这就要查找转发表。本章只讨论查找转发表的简单过程，而转发表是如何建立的则在下一章讨论。最后介绍三种广域网，即X.25网、帧中继网和采用ATM技术的广域网。-This chapter will discuss the basic concepts of wide-area network, wide area networ
