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.

Collision-free bandwidth-variable optical burst switching ring network

IEEE\/OSA Journal of Optical Communications and Networking, 2013
Recently, flexible bandwidth allocation has been proposed in an orthogonal frequency division multiplexing based elastic optical network, which is a promising technology for 100G and beyond optical networks. In this paper, for the first time we introduce

On regenerator placement in loss-less optical burst switching networks

International Conference on Telecommunications and Signal Processing, 2013
Optical burst switching suffers from burst contention, which can occur even under low load. This issue was investigated by Coutelen et al., 2009 and led to the CAROBS framework.

Analysis of continuous feedback Markov fluid queues and its applications to modeling Optical Burst Switching

International Test Conference, 2013
Optical Burst Switching (OBS) has been proposed as a candidate technology for the next-generation Internet. In OBS, packets are assembled into a burst, and a burst control packet is sent in advance to inform and reserve resources at the optical nodes in ...

Efficient Optical Resource Allocation and QoS Differentiation in Optical Burst Switching Networks Utilizing Hybrid WDM/OCDM

Journal of Lightwave Technology, 2012
In this paper, a QoS differentiation framework is proposed for an optical burst switching (OBS) multiservice network. Furthermore, hybrid wavelength division multiplexing and optical code division multiplexing (WDM/OCDM) scheme is used to mitigate the ...

Evaluation of burst retransmission in optical burst-switched networks

2nd International Conference on Broadband Networks, 2005., 2005
In this paper, we evaluate the performance of a burst retransmission scheme in which the bursts lost due to contentions in an OBS network are retransmitted at the OBS layer. The retransmission scheme aims to reduce burst loss probability in OBS networks.

Synchronous stream optical burst switching [PDF]

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 ...

Burst circulating threat in optical burst switched networks

2014 IEEE International Conference on Advanced Communications, Control and Computing Technologies, 2014
Optical network is a high speed network thus reduce the huge bandwidth demands and increase the internet users. Optical burst switched network is an optical networking technique that allows dynamic sub wavelength. OBS is viewed as compromise the optical packet switching and optical circuit switching networks.

Transmission mechanism based on burst filling in hybrid optical burst/circuit switching networks

China Communications, 2013
Hybrid optical switching networks make full use of the advantages of Optical Circuit Switching (OCS) and Optical Burst Switching (OBS). In parallel hybrid optical switching networks, edge nodes choose a switching mode for traffic and no longer change ...
