Periodically scheduled burst flows in optical burst switching networks

International Journal of Communication Networks and Distributed Systems, 2007
Providing flexible quality of service (QoS) for multiple classes of traffic is one of the important challenges in the design of optical burst switching (OBS) networks. In this paper, we propose a novel bandwidth reservation scheme for periodically scheduled bursts.

Techniques for optical packet switching and optical burst switching

IEEE Communications Magazine, 2001
Wavelength-division multiplexing appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. Several different technologies have been developed so far for the transfer of data over WDM.

Adaptive reliable optical burst switching

2nd International Conference on Broadband Networks, 2005., 2005
This paper presents the adaptive reliable optical burst switching (AR-OBS) paradigm that employs two-way reservation, and edge burst aggregation to guarantee deterministic data latency and loss rate under a distributed control plane. AR-OBS employs the adaptive robust fast optical reservation protocol (A-RFORP) to provide adaptive blocking recovery ...

Optical Burst Switching

2008
Switching in core optical networks is currently being performed using high-speed electronic or all-optical circuit switches. Switching with high-speed electronics requires optical-to-electronic (O/E) conversion of the data stream, making the switch a potential bottleneck of the network: any effort (including parallelization) for electronics to approach

Optical burst switching with burst access mode passive optical networks

2007 15th IEEE Workshop on Local & Metropolitan Area Networks, 2007
In this paper, we investigate the integration of passive optical networks (PONs) with optical burst switched (OBS) networks. Owing to the decomposition of the operations between the PONs and OBS nodes, serious problems have been observed. One of them is data burst assembly problem.

Synchronous stream optical burst switching

2nd International Conference on Broadband Networks, 2005., 2005
This paper presents a novel architecture of synchronous stream optical burst switching (SS-OBS), which employs a unified traffic control plane to enable a wavelength-routed optical network with integrated sub-wavelength grooming services to support sub-wavelength streaming traffic of constant bit rate (CBR) and variable bit rate (VBR) with guaranteed ...

Time sliced optical burst switching

IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428), 2004
Time Sliced Optical Burst Switching is a proposed variant of optical burst switching, in which switching is done in the time domain, rather than the wavelength domain. This eliminates the need for wavelength converters, the largest single cost component of systems that switch in the wavelength domain.

Optical Hybrid Switching – Combined Optical Burst Switching and Optical Circuit Switching

2004
In this paper, we propose a new optical hybrid switching technique which combined Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) using flow classification. In particular, this switching technique classifies incoming IP traffic flows into short-lived and long-lived flows for Quality of Service (QoS) provisioning according to traffic ...

Maximizing throughput for optical burst switching networks

IEEE INFOCOM 2004, 2004
In optical burst switching (OBS) networks, a key problem is to schedule as many bursts as possible on wavelength channels so that the throughput is maximized and the burst loss is minimized. Most of the current research on OBS has been concentrated on reducing burst loss in an ldquoaverage-caserdquo sense, and little effort has been devoted to ...

Buffering-deflection tradeoffs in optical burst switching

Photonic Network Communications, 2010
A very important issue in optical burst switching (OBS) networks is the excessive burst drop when no suitable network resources are found during path reservation. In this study, a network scenario is evaluated in which AWG-based optical nodes are used as burst router nodes within the optical network.
