چکیده

As the optical network evolves from static long haul connection provider to an adaptive and “smart” backbone solution, Optical Burst Switching (OBS) becomes an attractive scheme for its flexibility and efficiency. However, how to reduce data loss is a crucial issue in such an asynchronous and one way reservation system. In this paper, we study one contention resolution strategy in OBS networks: deflection routing. We extend an existing work to provide approximate and accurate models for the data loss analysis of single OBS node with and without wavelength conversion capability. The accuracy of our models are evaluated by simulation results.

Performance Analysis of Deflection Routing in Optical Burst-Switched Networks

This paper concerns itself with the performance of deflection routing in optical burst-switched networks based on Just-Enough-Time (JET) signaling. Generally speaking, buffer requirement is not vital for JET-based optical burst switching (OBS). However, if deflection routing is enabled, optical buffers are necessary to solve the insufficient offset time problem. A variant of priority queuing mo...

Intelligent Deflection Routing Protocol

Contention is the main source of burst loss in Optical Burst Switched (OBS) networks where deflection routing is one of the methods to resolve contention. Deflection routing requires enhancements only in the routing software without additional hardware installations. Its main goal is to successfully deflect a burst based only on a limited knowledge that nodes posses about their environment. In ...

Network Topology Impact on Optical Burst Deflection Routing

Deflection Routing is a key technique to resolve contention in optical burst-switched networks. Considering three different deflection routing strategies, we investigate the influence of network topology and of burst length on network performance in terms of dropping probability. OCIS codes: (060.0060) Fiber optics and optical communications; (060.4250) Networks

Performance comparison between Optical Burst Switching and Deflection Routing

Optical packet-switched networks of the near future will likely use no or very small number of optical buffers. We compare the delay-throughput performance of deflection routing and optical burst switching because both do not require the use of optical buffers. Simulations show that the simple packet drop-andretransmit contention resolution strategy of optical burst switching has a better perfo...

Small Group Multicast with Deflection Routing in Optical Burst Switched Networks

In this paper, we focus on the problem of effectively supporting a large number of small group multicasts in optical burst switched (OBS) networks. We first propose a multicast scheme for small group multicast in OBS networks. To reduce burst loss due to potential burst contentions, a deflection routing scheme for multicast is proposed. We then develop an analytical model to evaluate the perfor...
