Abstract
The novel applications require multiservice networks to guarantee quality of service (QoS). In this paper, we propose a multiclass admission control mechanism for providing QoS in optical burst-switched networks (OBS). The proposed mechanism admits bursts of a given service class according to network load and a class-associated parameter. Based on this parameter, referred as load level, it is possible to differentiate the burst blocking probability experienced by each service class. We also develop an analytical model for the proposed mechanism and evaluated its performance in different scenarios. Even when varying the offered load, the traffic amount of each service class, and the number of service classes, the proposed mechanism provides a lower blocking probability for the high-priority traffic in comparison with other similar admission control mechanisms
