In the previous chapters, we have discussed a variety of topics on wavelength-routed networks. A lightpath is physically set up through a suite of signaling mechanisms by way of dedicated control channels before optical data is launched, and is torn down after the connection ends.

On ordered scheduling for optical burst switching
Computer Networks, 2005Optical burst switching (OBS) is a promising optical networking paradigm for efficient transport of bursty IP traffic over wavelength division multiplexing (WDM) optical Internet networks. In OBS, the header of a burst is sent in advance of the data burst to reserve a wavelength channel at each optical switching node along the path.

Burst segmentation benefit in optical switching
IEEE Communications Letters, 2003The asymptotic ratio between the blocking probabilities of BS and JET protocols was derived as the number of wavelengths supported by the optical switch. BS offered a factor of ((1-c)2/c)k improvement in blocking probability value. This value can be more than two orders of magnitude for foreseeable dense WDM systems.

Performance Analysis of Optical Composite Burst Switching
IEEE Communications Letters, 2002 In this letter, we introduce a queueing model to study the performance enhancement in a so-called optical composite burst switching network (OCBS). Based on our model, we develop a simple analytical method to calculate the packet loss probability and we ...

Data burst grooming in optical burst-switched networks
2nd International Conference on Broadband Networks, 2005., 2005In this paper we address the problem of data burst grooming in optical burst-switched (OBS) networks. In OBS networks IP packets with the same edge node destination are assembled into larger packets called data bursts. Depending on the core node's switching technology, data bursts are required to have a minimum length. On the other hand, each IP packet

Time sliced optical burst switching
IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428), 2004Time 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 burst switching with burst access mode passive optical networks
2007 15th IEEE Workshop on Local & Metropolitan Area Networks, 2007In 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.

Maximizing throughput for optical burst switching networks
IEEE INFOCOM 2004, 2004In 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 ...

Slotted Optical Burst Switching (SOBS) networks
Computer Communications, 2006In this paper we study Optical Burst Switching (OBS) networks. Since OBS still suffers high loss ratio due to the lack of buffer at the OBS core routers, we study methods to reduce the loss without using optical buffers. We consider time-slotted OBS called Slotted OBS (SOBS), where routers are synchronized and only send fixed length bursts at the ...
