Dynamic bandwidth management as part of an integrated network management system based on distributed agents

This work was partially supported by the Spanish Research Council (CICYT) under contract TEL-99-0976. Abstract – In this paper, we present a system for dynamic network resource configuration in environments with bandwidth reservation and path restoration mechanisms. Our focus is on the dynamic bandwidth management results, although the main goal of the system is the integration of the different mechanisms that manage the reserved paths (bandwidth, restoration, and spare capacity planning). The objective is to avoid conflicts between these mechanisms. The system is able to dynamically manage a logical network such as a Virtual Path network in ATM or a Label Switch Path network in MPLS. This system has been designed to be modular in the sense that in can be activated or deactivated, and it can be applied only in a sub-network. The system design and implementation is based on a Multi-Agent System (MAS). We also include details of its architecture and implementation.
