M_OBS_SIM: A powerful Modular Optical Burst Switched (OBS) network SIMulator
Simulation Modelling Practice and Theory, 2006Abstract This paper introduces M_OBS_SIM, a network simulator conceived to evaluate the performance of networks where the Optical Burst Switching (OBS) paradigm is implemented. Its accurate design allows to investigate the behavior of optical edge and core routers, as well as to assess the performance of the whole optical network; its modular ...

QoS-Based Manycasting Over Optical Burst-Switched (OBS) Networks
IEEE/ACM Transactions on Networking, 2010Many distributed applications require a group of destinations to be coordinated with a single source. Multicasting is a communication paradigm to implement these distributed applications. However in multicasting, if at least one of the members in the group cannot satisfy the service requirement of the application, the multicast request is said to be ...

Performance analysis of an optical burst switching (OBS) network
2008 International Conference on Electrical and Computer Engineering, 2008This paper presents a burst loss rate (BLR) scheme suitable for slotted optical burst switched networks. An analytical model for burst loss rate is presented. The effect of several design parameters on the above performance measure is examined with the aid of simulations.

Optical burst switched (OBS) systems with segmentation-based dropping
e & i Elektrotechnik und Informationstechnik, 2008Optical burst switching is a technique for transmitting several packets, through an optical transport network, by assembling them in large data containers, known as bursts. These bursts can be of variable length and are separated from their headers. The header, known as control packet, is sent through the network using a separate control channel, to ...

Group-Scheduling for Multi-Service Optical Burst Switching (OBS) Networks
Photonic Network Communications, 2006We propose a new burst scheduling mechanism for Optical Burst-Switched (OBS) networks. The new approach is made possible by gathering data bursts into groups and performing the scheduling decision for each group collectively. In OBS group-scheduling, bursts will not be considered for scheduling until a pre-defined time period elapses, during which the ...

On the energy consumption in Optical Burst Switching (OBS) networks
2012 International Symposium on Computer Applications and Industrial Electronics (ISCAIE), 2012The tremendous growth in Internet traffic has led to a corresponding exponential increase in energy consumption. Optical Burst Switching (OBS) can provide an efficient solution for the next generation of Internet in minimizing energy consumption. This paper presents the energy consumption model of the OBS network.

Performance Analysis of Scheduling Algorithms in Optical Burst Switching (OBS) Networks
Second International Conference on Innovative Computing, Informatio and Control (ICICIC 2007), 2007OBS is an efficient paradigm that transporting traffic directly over optical links, and has received considerable attention. It seems a challenge to analyze scheduling problem. In this paper we model and analyze channel utilization performance of IAUC, OBS-GS and MWIS-OS algorithms.

Dynamic Load-Balanced Manycasting Over Optical Burst-Switched (OBS) Networks
Optical Fiber Communication Conference and National Fiber Optic Engineers Conference, 2009Data-loss in optical-burst-switched networks primarily occur due to contention of bursts at core nodes. We propose two dynamic congestion-based load-balanced manycast-routing techniques, namely load-balanced SPT and load-balanced DM that significantly improve blocking-probability and end-to-end delay.

Performance evaluation of TCP over optical burst-switched (OBS) WDM networks
IEEE International Conference on Communications, 2003. ICC '03., 2004This paper studies the performance of TCP transport protocol over an optical burst-switched (OBS) wavelength division multiplexed (WDM) wide-area network. Typically, an OBS network consists of optical core routers and electronic edge routers connected by WDM links.

Timescale analysis for wavelength-routed optical burst-switched (WR-OBS) networks
Optical Fiber Communication Conference and Exhibit, 2002The relationship of three timing parameters in the WR-OBS network architecture has been identified and investigated, to quantify the limits on the operation of a dynamic network. An adaptive burst assembler at the network edge provides an accurate estimation of the maximum edge delay whilst preventing buffer overflow, depending only on the mean and ...
