Abstract
This paper presents a Service Level Agreement (SLA) negotiation technique for Instantaneous Request (IR) call connections based on information in context of Book-Ahead (BA) reservation. Resource sharing between IR and BA reservation imposes a number of problems in a QoS-enabled network. One of the problems is preemption of on-going IR calls. Call admission control models proposed in literature reduce high preemption rate at the cost of higher call blocking rate and lower resource utilization. The negotiation technique proposed in this paper is based on information like look-ahead time for BA calls and negotiable requirements of IR calls. The technique allows admission of some of the IR calls that would otherwise be blocked due to resource scarcity arising from BA call activation. Simulation results show that the proposed negotiation based call admission control model achieves the desired objective of higher resource utilization and lower call blocking rate.
