Book-ahead call routing for flexible lifetime

For persistent and guaranteed quality of service (QoS), a Book-Ahead (BA) call connection is required to declare its exact lifetime in advance which is not always possible for many BA applications. In this letter, we present a model for extendable BA lifetime through adoption of a new BA routing scheme based on the calculation of call extension failure probability of BA call(s) for each link in the network.
