第5题:

说明PVC和SVC的区别,以及建立SVC的过程。


正确答案: 交换虚电路 SVC 在一次通信过程中具有呼叫建立、数据传输和呼叫清除三个阶段,网络设备为用户动态地按需分配线路传输能力;而永久虚电路 PVC 则不用呼叫建立连接,也不用清除连接,用户如果向网络预约了 PVC 服务,在两个用户之间就存在了永久虚电路,可直接进行数据传输,就好像具有一条专线一样。
一个典型的 SVC 建立过程如下:要求通信的 DTE 一方为主叫方,它向其 DCE 发出一个呼叫请求分组。这个请求分组的信息包括虚电路号、主叫 DTE 地址和被叫 DTE 地址等。通信子网选择合适的路由传送到被叫 DCE ,再呼叫被叫 DTE 。被叫 DTE 若接受呼叫,则发出接受分组,通过网络传到主叫 DTE ,这样虚电路就建立了。
