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.

Design of burst for optical burst switching
International Conference on Communication Technology Proceedings, 2003. ICCT 2003., 2004A probable structure of burst for optical composite burst switching (OCBS) and a new method supporting QoS to set offset time between control packet and macropacket are put forward. The algorithm to realize OCBS is also proposed. According to the result of the performance analysis, OCBS has a lower packet loss probability and higher channel efficiency ...

The concept of burst switching was proposed initially in the context of voice communications by Haselton (1983) and Amstutz (1983; 1989) in the early 1980s. More recently, in the late 1990s, optical burst switching (OBS) was proposed as a new switching paradigm for the so-called optical Internet in order to overcome the technical limitations of optical

Periodically scheduled burst flows in optical burst switching networks
International Journal of Communication Networks and Distributed Systems, 2007Providing 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, 2001Wavelength-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., 2005This 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 ...

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, 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.

Synchronous stream optical burst switching
2nd International Conference on Broadband Networks, 2005., 2005This 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), 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.
