Abstract

An apparatus and method for adaptive route selection between a source and a destination node where multiple routes are available. Link state variables are monitored and updated when call termination requests or call arrival requests are received. When a call arrival request is received, a list of potential routes between the source and destination nodes is determined. A best route is selected by evaluating the link states for each potential route. A call is attempted on the best route and if the attempt is not successful, a call is attempted using the next best route and so on.
