Executive Summary

The differentiated requirements of applications over this multitude of access networks need a mechanism for resource negotiation and management. The aim of the paper is to present an inter-domain end-to-end mechanism used for best path selection in a hybrid access WLAN-UMTS scenario, based on one-way delay estimation as the network parameter requested by the application and managed by mobile agents. Further, based on the obtained results, the paper proposed an extended mechanism using profiles, a set of aggregate parameters like bandwidth, delay, jitter, etc. The mechanism is called I-NAME (In-Network Autonomic Management Mechanism) and it is used for network resource reservation and management functions.
