Towards global service level guarantee within autonomic computing systems
International audience; In this paper, we specify a global service level guarantee including not only QoS but also security and taking into account user mobility. This global service level could be guaranteed within several autonomic computing systems managed by different autonomic domain managers. For that purpose, we propose an end-to-end Service Level Negotiation Protocol, called SLNP, to provide those autonomic managers with a negotiation capability. This allows achieving an agreement on the service level of each offered service between the different domains involved in the transport of that service. SLNP Implementation is made of Web Services technologies to enable interoperability in …

Improvement of a Service Level Negotiation Protocol using Formal Verification
International audience; The goal of the pervasive connectivity is to enable mobile users to be permanently connected to the Internet. Mobile users are often connected to wireless networks and consuming services that require quality of service guarantees. Accessing services using wireless technologies may make the service delivery vulnerable to security attacks because of the open medium of these technologies. In this context, we need to guarantee both quality of service and security for mobile users communications. In this paper, we present a protocol for service level negotiation which covers both quality of service and security and assigns a profile to each user in order to optimize and a…
A global service level guarantee in NGN networks
In this paper, we propose an end-to-end service level negotiation protocol which enables a global service offer covering quality of service (QoS) and security while taking into account user's mobility in this offer. This protocol provides all the domains involved in the transport of a various offered services with a negotiation capability to achieve an agreement on a service level. This paper shows also results of measurements evaluating the performances of the considered negotiation protocol and security impact on QoS.
