Multiservice optical packet switched networks : modeling, performance evaluation and QoS mechanisms in a mesh slotted architecture

Résumé

Optical packet switching (OPS) technologies are among the most promising solutions for next generation network architectures. Resource contention resolution and Quality of Service (QoS) management mechanisms have been developed in order to remedy the lack of optical buffering and implement multi-service support in OPS networks. In this paper we propose an analytical model for the access and core nodes of a multiservice mesh network architecture which operates in a synchronous slotted transmission mode. The proposed model captures the effect of the client traffic matrix and considers a priority-based multi-service support. Moreover, we elaborate two resource management mechanisms: cumulative credits mechanism (CCM) and distributed deflection routing (DDR). The former solves inter-class fairness issues at the access nodes and the latter optimizes the resource contention resolution in the core of the network. We use our analytical model to show the interest of the developed mechanisms. The results obtained by the proposed model are validated and analyzed through several simulation scenarios
