Extension of the PNNI to support mobility management and handoffs in WATM networks based on CORBA

This paper considers an extension to the private network-to network interface (PNNI) for the support of host/terminal mobility. It provides an introduction and the background. Different concepts are then introduced, and an implementation of PNNI mobility support signalling, based on Java/CORBA, is presented. Finally, we present performance figures and base line results for Java/CORBA based signalling systems.
