OBS contention resolution performance

In this paper, a performance comparison of resolution policies specific to optical burst switching is presented. A framework, based on a reduced-load approximation, is developed to estimate path blocking probabilities in an optical burst switching network of arbitrary topology, in which any combination of the following resolution policies is in place: burst deflection, burst segmentation and li...

Enhancing Fairness in OBS Networks

Optical Burst Switching (OBS) is a promising solution for all optical Wavelength Division Multiplexing (WDM) networks. It combines the benefits of both Optical Packet Switching (OPS) and Optical Circuit Switching (OCS). In this switching, data are transmitted in the form of bursts. Fairness is the main constraint in high-performance OBS network. In order to improve the fairness, a method known ...

Proportional QoS over OBS networks

Optical Burst Switching (OBS) is considered as an efficient switching technique for building the next generation optical Internet. An offset-time based scheme has recently been proposed in order to provide qualityof-service (QoS) in OBS networks. Unfortunately, the proposed service differentiation has several problems. The aim of this paper is to address these problems and introduce the concept...

Modeling OBS Network in OMNeT++

The data transmission by high-speed optical networks has upward trend. Various techniques of multiplexing are used in optical communication networks to satisfy growing demands. Wavelength division multiplexing is currently mostly used multiplex method due to its great advantages. Since the current optical communication networks are based on internet protocol, the optical burst switching present...
