نویسنده
چکیده
Optical networks evolve fast. Nowadays many technologies of optical networks are using. But there are some restrictions which make limited of the possibilities of the optical networks. Contention Resolution is one of them. There are several technologies of reducing of Contention Resolution. They will be analyzed in this paper. The advantages and disadvantages of these technologies will be described and discussed at the end of the paper. Keywords— Optical packet switching networks, contention resolution, optical buffering, fiber delay lines, wavelength conversion, deflection routing.

متن کاملSupporting QoS with look-ahead window contention resolution in optical burst switched networks
Optical burst switching (OBS) has been proposed as a competitive hybrid switching technology to support the nextgeneration optical Internet. This paper addresses the problem of contention in OBS networks and introduces a new contention resolution algorithm called Look-ahead window Contention Resolution (LCR) that can also support service differentiation. Simulation results show that the perform...
متن کاملEnd-to-End Contention Resolution Schemes for an Optical Packet Switching Network With Enhanced Edge Routers
This paper investigates contention resolution schemes for optical packet switching networks from an end-to-end perspective, where the combined exploitation of both core routers and edge routers are highlighted. For the optical-core network, we present the architecture of an optical router to achieve contention resolution in wavelength, time, and space domains. Complementing the solution involvi...
متن کاملA Distributed Contention Resolution Scheme to Reduce Blocking Probability in Optical Burst Switching Networks
In this paper, we propose a distributed contention resolution scheme to reduce blocking probability in optical burst-switching networks. The scheme takes priority, propagation delay from the ingress router, and the burst-size into account to resolve contention, and guarantees that at least one of the bursts succeeds when contention occurs. We use a control packet to delay transmission of the co...
متن کاملA Novel Packet Switch Node Architecture for Contention Resolution in Synchronous Optical Packet Switched Networks
Packet contention is a key issue in optical packet switch (OPS) networks and finds a viable solution by including optical buffering techniques incorporating fiber delay lines (FDLs) in the switch architecture. The present paper proposes a novel switch architecture for packet contention resolution in synchronous OPS network employing the packet circulation in FDLs in a synchronized manner. A mat...
