Résumé: In an integrated network, multiple service classes may exist with different priorities and quality-of-service (QoS) characteristics. Path selection algorithms play an essential role in supporting the QoS requirements of a session in the integrated network. However the existing path selection algorithms may allow a session of a high priority class to be preempted instead of that of the lower priority class. We analyze the mentioned problem and propose a new path selection algorithm which uses not only the amount of residual bandwidth but also the Class Distribution Information of residual bandwidth (RB-CDI) in its path selection procedure.
