In the policy-based network management, the local policy decision point (LPDP), is used to reach a local decision. This partial decision and the original policy request are next sent to the PDP which renders a final decision. In this paper, we propose to give a real autonomy to the LPDP in term of internal decision and configuration. The LPDP is considered as a learning BDI agent that autonomously adapts the router’s behavior to environment changes

The Next Steps In Signaling (NSIS) working group has been recently created to design a generic IP signaling protocol supporting various signaling applications. This paper presents the Generic In Signaling Service Protocol (GISP) we designed considering the current outputs of the NSIS working group. In particular, we focus on the state management and message fragmentation using a simple mechanism to detect the path MTU.

This article presents limitations of current network management standards in the context of comprehensive distributed system supervision. As a proposed solution, the article describes the GeneSyS project achievements, a modern approach allowing straightforward integration of all monitoring/control means, as well as providing basic intelligence capabilities. These issues are illustrated on several industrial examples.

Common multicast tree shared by all layers/streams belonging to one session, is essential to provide multicast-based congestion avoidance. It enables both synchronization of layered data (in the case of layered multicast) or streams (in the case of multicast stream replication) and stable congestion control. Although many authors have been addressed the problem of multicast transmission, the methodology of building common delivery trees still remains an unresolved issue. In the paper, a new solution of that problem is proposed — a multigroup communication based on active network technology.

Recently, a great consortium on Generalized Multi Protocol Label Switching (GMPLS) is emerging as the control plane for next generation optical backbone networks. This article proposes guidelines for managing optical networks controlled by GMPLS in a policy based fashion. A flexible management solution is presented especially for optical network issues, where the service management system efficiently impacts the control plane offering the possibility to dynamically change network functionality to enhance the controllability of optical networks.

To configure current networks a large number of parameters have to be taken into account. Indeed, we can optimize a network in different ways: Optimize battery capacity, optimize reliability of the network, optimize QoS, optimize the security, optimize the mobility management, and so on. In this paper we begin by proving that the TCP/IP architecture is not the best protocol in a specific wireless experiment: the energy consumption on a Wi-Fi network. Then, we propose a new architecture, Goal-Based Networking (GBN) architecture, using adaptable protocols named STP/SP protocols (Smart Transport Protocol/Smart Protocol) able to optimize locally the communications through the networks. Finally we discuss the pros and cons of this new architecture.
