“…The SLNP protocol, considered in this paper, belongs to the second category. In fact, it was specified to enable the negotiation of service level in an interoperable manner through the use of Web Services [15]. Therefore, it is an out-of-band signaling protocol which provides domain managers with interoperability.…”

Based on the IP technology, the next generation networks (NGN) must overcome the main drawbacks of this technology consisting in the lack of quality of service (QoS), security and mobility management. To ensure a service offer in an NGN environment, a protocol for negotiating a service level can be used. However, most of the existing negotiation protocols allow the establishment of a service level which includes only QoS. As for security and mobility, they were often not covered by these negotiations, and therefore managed independently. However, securing a service can cause degradation of the QoS, and the mobility of a user can change the service needs in terms of QoS and security. Thus, we need to simultaneously manage QoS and security while taking into account user's mobility. In this ISSN 1943-3581 2011 www.macrothink.org/npa 55 context, we propose an end-to-end NGN architecture with several autonomous domains, where each domain is under the authority of an autonomic domain manager. We provide those autonomic managers with a negotiation capability to achieve an agreement between the different domains involved in the transport of various offered services. This agreement may cover different aspects such as QoS, security and takes into account the user profile. The negotiation process will be based on SLNP (Service Level Negotiation Protocol) which uses Web Services technologies in order to enable interoperability between the managers of the different autonomous domains involved in the service transport.

“…SLNP was defined to guarantee an end-to-end service level negotiation between the managers of the different domains implied in a service offer [15]. This negotiation is performed thanks to the exchange of negotiation messages which enable the establishment, the modification and the termination of a service level.…”
