A performance analysis of distributed QoS negociation during establishment session

Résumé

In order to achieve guaranteed services, we need to negotiate network resources providing the required quality of services (QoS). For this reason, the common set-up process of service session is divided into three phases. At first, the application specifies its QoS requirements, then, the QoS parameters at IP level and MAC level are successively specified and finally the network applies the negotiated QoS configuration. In this paper, we propose to negotiate at the same time the QoS parameters at both levels. An optimization of this approach has also been discussed. This optimization focuses on distributing negotiated QoS parameters between several entities located in different hierarchical levels. The assignment of parameters is dynamically configured. Therefore, this paper proposes a performance model to compare the new combined-distributed negotiation process with the negotiation processes applied in UMTS Release 5 (R5) [4] during session establishment. Numerical results show that the proposed approach is more scalable on the network side than the UMTS approach.
