Distributed and Iterative Algorithms for the Management of Telecommunications Systems

Team presentation

Today, research on network and service management as well as Web Services mainly focuses on issues of software architecture and infrastructure deployment. However, these areas also involve algorithmic problems such as fault diagnosis and alarm correlation, testing, QoS evaluation, negotiation, and monitoring. Our group focuses on these issues. More precisely, we address models and algorithms for distributed network and service management, and the distributed management of Web services and business processes. Our main industrial ties are with Alcatel-Lucent, on the topic of networks and service management.

Research themes

Our research topics are structured as follows: 1/ Fundamentals of distributed observation and supervision of concurrent systems (event structures, nets, scenarios; timed and probabilistic extensions thereof); 2/ Algorithms for distributed management of telecommunications systems and services; 3/ Self-modeling: as our models cannot be built by hand, we address the new topic of self-modeling, i.e., the automatic construction of models, both structural and behavioral; 4/ Web Services orchestrations, functional and QoS aspects; and 5/ Active XML peers for Web scale data and workflow management.

International and industrial relations

Our main industrial ties are with Alcatel (and formerly France-Telecom), on the topic of networks and service management. We are active members of the Joint Laboratory Bell Labs France - INRIA on Self-Organizing Networks. Also, we study, in cooperation with Serge Abiteboul (GEMO project-team, INRIA-Saclay) and Anca Muscholl (Labri, Bordeaux), an Active XML infrastructure for business processes based on Web services. We participate to the IP-STREP DISC european project on control and supervision of discrete event systems. Finally, we have a partnership agreement with National University of Singapore and the University of Chennai.
