Abstract:
|
The emergence of a broad range of network-driven applications (e.g., multimedia, online
gaming) brings in the need for a network environment able to provide multiservice capabilities with diverse quality-of-service (QoS) guarantees. In this paper, a medium access control protocol is proposed to support multiple services and QoS levels in optical burst-switched mesh networks without wavelength conversion. The protocol provides two different access mechanisms, queue-arbitrated and prearbitrated for connectionless and connection-oriented burst
transport, respectively. It has been valuated through extensive simulations and its simplistic form makes it very promising for implementation and deployment.
Results indicate that the protocol can clearly provide a relative quality differentiation for connectionless traffic and guarantee null (or negligible, and thus acceptable) burst loss probability for a wide range of network (or offered) load while ensuring low access delay for the higher-priority traffic. Furthermore, in
the multiservice scenario mixing connectionless and connection-oriented burst transmissions, three different prearbitrated slot scheduling algorithms are evaluated, each one providing a different performance
in terms of connection blocking probability.
The overall results demonstrate the suitability of this architecture for future integrated multiservice optical networks. |
