In this paper, we analyze the performance of the load-level-based admission control mechanism (LLAC) for optical burst-switched networks in a multilink scenario. The goal of this mechanism is to differentiate the blocking probability of a given service class according to the network load and a class-associated parameter, called load level. For the proposed mechanism, we develop a multilink analytical model based on the reduced load approximation method, which provides a more accurate blocking probability estimation than a single-link model. With the multilink model, the performance of the load-level- based mechanism is even better than using a single-link model. For the analyzed scenarios, high-priority bursts experiences a blocking probability up to 60% lower than the one provided by the single-link model. The results also show that the load- level-based mechanism effectively differentiates the services in all analyzed scenarios, when compared to other similar mechanisms.
