Abstract. Programmable and active networks allow specified classes of users to deploy dynamic network services adapted to data streams requirements. Currently most of researches performed on active networks are conducted in research laboratories. In this paper, we explore the design of IAN 2 an Industrial Autonomic Network Node able to be deployed in industrial context. Performance, dynamic programmability and fault-tolerance issues of software and hardware components have been prospected. First experimental evaluations on local platforms are presented.

Keywords: Telemaintenance, mobility, wireless networks, active andprogrammable networks, Since the year 2000, the performances that are cooperative work obtained from the point of view of the networks processors make it possible to use real distribution 1. Introduction applications. Particularly, in remote maintenance domain, the network quality makes it possible to have Currently, problems of maintenance for several expertises readily available. production materials in industry are often pushed into As a result, the quality of maintenance increases as it the background in view of the requirements of becomes faster, more reliable and highly efficient.production [9]. This situation is due mainly to an The TEMIC Tele-maintenance application will absence of maintenance policy and to the costs connect mobile users (via their PDA Terminal) to caused by this one, in particular in term of mobility Information Systems in order to perform activities in of the qualified personnel carrying out maintenance. areas such as corrective, preventive and conditional With the maturation of new telecommunication maintenance.technologies, the industrial companies want to The TEMIC Tele-maintenance platform is based on a integrate these projections to activate the three-level architecture: Collection and Surveillance, interventions of the specialists on site and thus to Intervention and Reporting, Diagnosis and decrease times of inactivity of the machines. The Collaboration. The use of wireless networks is one of high speed communications make it possible to have the TEMIC distinctive characteristics, which allows quickly several concurrency expertises. Maintenance connection between mobile Tele-maintenance thus becomes faster, more reliable and of better qualified actors. Another distinction is the design of quality. active and autonomous industrial network devices that are easily and efficiently deployable in an industrial setup.
