Towards global service level guarantee within autonomic computing systems

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 the negotiation process between different autonomic computing systems using heterogeneous technologies.
