Performance Issues in Optical Burst/Packet Switching [PDF]

, 2009
This chapter summarises the activities on optical packet switching (OPS) and optical burst switching (OBS) carried out by the COST 291 partners in the last 4 years. It consists of an introduction, five sections with contributions on five different specific topics, and a final section dedicated to the conclusions.

Design of wavelength converting switches for optical burst switching

Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2003
Optical burst switching (OBS) is an experimental network technology that enables the construction of very high capacity routers, using optical data paths and electronic control. In this paper, we study two designs for wavelength converting switches that are suitable for use in optical burst switching systems and evaluate their performance. Both designs

Traffic characteristics analysis in optical burst switching networks with optical label processing

Semina: Ciências Exatas e Tecnológicas, 2007
An analysis is carried out with burst-switching optical networks which use label processing consisting of orthogonal optical codes (OOC), considering traffic characteristics such as length/duration and arrival rate of bursts.

QoS Routing Algorithm for OBS Networks Based on a Multi-Objective Genetic Algorithm

IEEE Access, 2022
To optimize the QoS of optical burst switching networks, a QoS routing optimization algorithm based on a multi-objective genetic algorithm is proposed. A Bayesian network model is used to locate the fault of optical burst switching network and obtain the

Optical burst switching with large switching overhead [PDF]

2006 IEEE International Conference on Communications, 2006
The optical burst switching (OBS) schemes to date assume that the switching overhead at intermediate nodes is either negligible or can be considered as part of the processing delay of the control packet. In this paper, we will show that the switching overhead can have a significant impact on the performance of OBS.

QoS provisioning for Composite Burst Assembly with Burst Segmentation in Optical Burst Switching (OBS) Networks [PDF]

Kirkuk Journal of Science, 2015
Optical Burst Switching (OBS) is one of the suggested that switching paradigms be used in Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks along with Optical Circuit Switching (OCS) and Optical Packet Switching (OPS).

Cost-based burst dropping strategy in optical burst switching networks [PDF]

, 2005
Optical burst switching (OBS) is a new paradigm for future all-optical networks. Intentional burst dropping is one of techniques used to achieve desired quality of service. In this paper we note that some bursts are more likely to cause contention.

Performance Evaluation of the Labelled OBS Architecture [PDF]

, 2010
A comparison of three different Optical Burst Switching (OBS) architectures is made, in terms of performance criteria, control and hardware complexity, fairness, resource utilization, and burst loss probability. Regarding burst losses, we distinguish the
