A framework for optical burst switching network design
IEEE Communications Letters, 2002 We analyze optical burst switching (OBS) systems. The analysis leads to a framework which provides guidelines for OBS design. We identify conditions for OBS feasibility and the relationship between burst size, or equivalently burst assembly delay, and ...

Optimization scheduling for optical burst switching (OBS) networks
SPIE Proceedings, 2006ABSTRACT Optical Burst Switching (OBS) is a promising solution for the future Internet and has attracted many attentions. In OBS network a key issue is channel scheduling. The objective of existing channel scheduling schemes is to maximize the number of bursts to be transmitted. Unfortunately it does not mean the maximum channel utilization.

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 ...

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 ...

Architecture and Performance of A Next-Generation Optical Burst Switch (OBS)
2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006Optical burst switching (OBS) is a promising technique for next-generation optical switching networks which attempts to address the problem of efficiently allocating resources for bursty traffic. In traditional OBS, an entire burst is discarded when all output wavelengths are engaged at the arrival instant of the burst.

TCP Over Optical Burst Switching (OBS): To Split or Not To Split?
2008 Proceedings of 17th International Conference on Computer Communications and Networks, 2008TCP-based applications account for a majority of data traffic in the Internet; thus understanding and improving the performance of TCP over OBS network is critical. In this paper, we identify the ill-effects of implementing TCP over a hybrid network (IP-access and OBS-core).

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.

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.

BAIMD: A Responsive Rate Control for TCP over Optical Burst Switched (OBS) Networks
2006 IEEE International Conference on Communications, 2006Additive Increase Multiplicative Decrease (AIMD) window adjustment mechanism has been embedded in TCP in order to regulate the transmission rate in modern communication networks. In recent years, the AIMD (1,0.5) traffic regulation mechanism along with possibly additional enhancements, such as false timeout detection and explicit notification, has been

Impact of TCP synchronization on capacity dimensioning of Optical Burst Switched (OBS) links
2012 17th European Conference on Networks and Optical Communications, 2012We study the effect of TCP synchronization on Optical Burst Switched (OBS) networks and its impact on capacity dimensioning. The synchronization of TCP flows appears when a burst with segments from different TCP flows is discarded, making that all TCP flows reduce their transmission rate at the same time, leading to inefficient bandwidth sharing.
