Abstract

"The development of Internet as well overall communication technologies has created a very competitive communication market. In fact, there is no doubt that every company and perhaps every person in the world will have an Internet physical or wireless access via ISPs (Internet Service Provider). Thus the Internet became a very complex worldwide network which objective it to provide not only connectivity to end user but also services with a certain QoS (Quality of Service). Although, the effort made by each ISP to provide this QoS, it is not very easy to provide this QoS from access point of the customer to the destination point. The main difficulties are the negotiation process between ISPs in order to agree for the terms of collaboration and the deployment and management of the network in order to satisfy these agreements. It is recognized now that Policy-Based Networking became a key concept to facilitate the deployment of management strategy in IP based networks. Although, already existing solutions, they can operate only in a particular domain while the customer request for an end-to-end deployment. Thus, it is necessary to extend this approach in order to integrate mechanisms that permit satisfy end-to-end SLA (Service Level Agreement) upon a number of administrative domains. Thus the objective of this paper is to propose a solution that allow the interoperability between various policy domains. The approach is based on mobile agents to facilitate the negotiation between the different domains. Customer or ISP Policy Based Management System delegate to a mobile agents the responsibility to negotiate the terms of SLA on their behalf . The mobile agent negotiate according to a set of policies defined by the Customer or the initiating ISP."
