广域网WAN一般最多只包含OSI参考模型的底下三层，而且大部分广域网都采用存储转发方式进行数据交换，也就是说，广域网是基于报文交换或分组交换技术的（传统的公用电话交换网除外） 。
广域网中的交换机先将发送给它的数据包完整接收下来，然后经过路径选择找出一条输出线路，最后交换机将接收到的数据包发送到该线路上去，以此类推，直到将数据包发送到目的结点 。
广域网可以提供面向连接和无连接两种服务模式，对应于两种服务模式，广域网有两种组网方式：虚电路（ virtual circuit）方式和数据报（ data gram）方式，下面我将分别讨论广域网的两种组网方式，并对它们进行比较 。

1、覆盖范围广通信距离远，可达数千公里以及全球 。
2、不同于局域网的一些固定结构，广域网没有固定的拓扑结构，通常使用高速光纤作为传输介质 。
3、主要提供面向通信的服务，支持用户使用计算机进行远距离的信息交换 。
4、局域网通常作为广域网的终端用户与广域网相连 。
5、广域网的管理和维护相对局域网较为困难 。
6、广域网一般由电信部门或公司负责组建、管理和维护，并向全社会提供面向通信的有偿服务、流量统计和计费问题 。
