Among the promising solutions for next generation Internet backbone, one can consider optical burst switching (OBS) technology. This technology does not, however, provide suitable quality-of-service (QoS) support. Several schemes have been proposed to provide QoS differentiation in OBS networks. The majority of these schemes are based on a relative QoS model in which the performance of a given traffic class is defined in comparison with other classes. A set of mechanisms have been proposed to provide an absolute traffic loss guarantee, but no mechanism has been proposed to handle absolute transmission delay in OBS networks. The aim of this paper is to propose a solution to provide an absolute transmission delay guarantee over an OBS network and thus support emerging multimedia applications with delay and bandwidth constraints based on a network architecture that is suitable for OBS switching and QoS provisioning. We also develop an analytic model based on a queuing system of the proposed solution. Finally, simulation experiments are conducted to validate the proposed scheme and study its features.

Among the promising solutions for next generation Internet backbones, one can consider the optical burst switching (OBS) technology. One of the main aspects in the design of optical burst-switched networks is the development of a burst admission control protocol suitable for QoS provisioning. In this paper, we develop a method to address the call admission control (CAC) in OBS networks that is QoS-oriented. For this, an analytic model is developed for formulating the burst admission control problem. A QoS-constraints based burst admission control protocol is developed. Finally, simulation experiments are performed to validate the proposed schemes.

The considered architecture is mainly based on the use of a new burst assembly and segmentation technique and a specific contention resolution scheme that combines wavelength conversion, burst segmentation, and optical buffering.…”

Optical Burst Switching (OBS) technology offers a promising solution for the next generation optical Internet. Since, TCP protocol is the most dominant transport protocol for the Internet, it is essential to address the implementation of TCP over the OBS technology. The main consideration in TCP performances over OBS is the interaction between the TCP congestion control mechanism and OBS-specific schemes. Different studies have considered TCP issues in OBS networks. It is noteworthy to note that all developed studies have not considered contention resolution at OBS layer, which may have a significant impact on TCP performances. In this paper, we address the implementation of TCP protocol over a novel OBS network architecture supported by a specific contention resolution scheme based on wavelength conversion, burst segmentation and optical buffering. For sake of better performances, we propose a segment retransmission scheme in which segments lost in case of contention resolution failure are retransmitted at the OBS layer. Also, we develop an analytic model for the mathematical analysis of TCP performances over OBS networks implementing these schemes. Finally, simulation experiments are conducted to validate the proposed approach and evaluate its performances.
