TodayNULLs networks are made of a large number of Network Elements (NEs) such as routers, firewalls, gateways, hosts, etc., each performing a set of elementary functions related to routing, security management, resource reservation, QoS management, etc. More sophisticated functions such as configuration of NEs, optimization of routing tables, troubleshooting, etc., are mainly managed in a centralized fashion often involving human intervention. However, networks are more and more faced with rapidly changing situations and increasingly complex configurations which are harder and harder to be adequately managed in a centralized manner, because of timing issues (collecting and processing information takes time) and complexity issues (dealing with networks centrally/globally is increasingly complex). In this paper we propose a Pilot-based Architecture (P2A) for future network control and management. This architecture is based on Distributed Intelligent Agents. This solution permits to perform a number of control and management functions in a decentralized way, dealing locally with simpler situations in a more responsive way. The P2A is made of Distributed Intelligent Agents, each capable of sensing and observing events and changes occurring locally. Agents communicate among neighbours to improve their knowledge of the situation in their neighbourhood and to make consolidated/coordinated decisions within an area of the network.
