Networks and Services management solutions are now moving from centralised platforms to distributed approaches. In order to reach a higher level of scalability and flexibility, an attractive solution can be based on cooperative intelligent agents. This raises new requirements for communication between management entities, as it implies not only exchange of(More)
Cooperative Management has appeared as a promising paradigm on which Network and System Management (NSM) solutions should be partially or entirely based. This paper proposes a conceptual framework to obtain, from any CIM schemas, NSM frame-based ontologies which can then be used in cooperative management solutions. 1. INTRODUCTION From a technological(More)
VoIP is significantly reducing the cost of transmitting telephone calls and enabling small companies to enter the $50 billion marketplace. Many telcos and ISPs are entering. pages. TMN is a network monitoring system that allows telecommunications providers to monitor every element of their networks. While TMN is a powerful tool for controlling. Marketing'(More)
The high complexity of existing networks and services has led to the need to increase the autonomy of management solutions. This article presents a generic agent-based framework as a first step towards the conception of self-managed systems. This conceptual framework consists of groups of management agents coupled with managed resources and endowed with(More)
We study some structural aspects of the subspaces of the non-commutative (Haagerup) L p-spaces associated with a general (non necessarily semi-finite) von Neumann algebra a. If a subspace X of L p (a) contains uniformly the spaces ℓ n p , n ≥ 1, it contains an almost isometric, almost 1-complemented copy of ℓ p. If X contains uniformly the finite(More)
This works is in keeping with the extension of Z so as to deal with the speciication and design of real-time safety-critical systems. The Z speciication language has been found useful for specifying large commercial systems, but is weak in its ability to deal with complex features of real-time systems such as concurrency, synchronization between processes(More)
La population porcine des Antilles françaises est représentée principalement par deux types génétiques : le Large White et le porc indigène appelé « porc Créole o ou porc « Planche ». A partir des enregistrements de notre troupeau expérimental, les performances de repro-ductiou de ces deux souches ont été comparées. L'âge et le poids à la puberté sont(More)
Before significant effects may be felt in service utilization by the user, detection of QoS degradation is a desirable requirement of service management. Management approaches define management information for each managed resource in a distributed environment, but a problem occurring on a resource denies access to its management information. A service has(More)
