QoS based routeing for ATM networks

The deployment of optical fibers with the emergence of the ATM technology which relies on a virtual call (VC) model is the necessary infrastructure to support modern applications such as multimedia. We propose to extend the classical method for packet switching, namely the distance vector and the link state method to cover these new user requirements. We present an ATM routeing architecture using route recording and source routeing which is based on "pre-computed" and "on-demand" routes.
