一种连接路由更改协议

A Connection Rerouting Protocol

在无线ＡＴＭ网中发生交换机间移交时，为了在连接期间保证连接的带宽和时延，提出一种结合路径扩展和路径优化的连接路由更改协议。路径扩展参照带宽－时延－受限路由问题加以解决。当存在一条可能的移交路径，它的时延超过时延限制时就激活路径优化进程对移交段进行优化。

To guarantee the bandwidth and delay of a connection during its connection lifetime when inter-switch handoff occurs in wireless ATM networks, we propose a connection rerouting protocol which includes path extension and path optimization .Path extension is resolved modeled as a bandwith-delay-constranied path problem. Path optimization is invoked whenever one of the potential handoff paths exceeds the delay constraint.
