Planning OBS networks with QoS constraints
Photonic Network Communications, 2007The design of OBS networks that guarantee QoS provisioning for different classes of traffic is a major topic under current research. In this work we formulate a unified framework for studying QoS in OBS networks with a GMPLS-based control plane. We use this framework in order to investigate two problems. First, the configuration of the parameters of an

Threats and vulnerabilities on TCP/OBS networks
2012 International Conference on Computer Communication and Informatics, 2012TCP/OBS networks are feasible networks for communication in future and Optical Burst Switching (OBS) is the promising technology solutions for this network. In these networks the data transfer is held in the form of bursts. Adequate amount of research work is done in this domain. Even though OBS has an advantage of transferring data with good speed but

Routing Scheme for OBS Networks
Journal of Optical Communications and Networking, 2012We observe that routing, in optical burst switching (OBS) networks, is basically motivated by reducing contention-induced loss and not by the objective of global resource optimization. Here, we propose a routing scheme for OBS networks that minimizes the burst loss probability of individual bursts and at the same time achieves the routing goal of ...

The application of OBE to neural networks
2004 IEEE International Joint Conference on Neural Networks (IEEE Cat. No.04CH37541), 2005In 1989, Singhal and Wu showed that training a feed forward neural network can be viewed as an identification problem for a nonlinear dynamic system using an extended Kalman filter algorithm, which can converge in few iterations. In this paper, a new type of optimal bounding ellipsoid (OBE) algorithm is presented, which is a set-membership ...

2012 14th International Conference on Transparent Optical Networks (ICTON), 2012
In this paper, we evaluate, for certain scenarios, the achievable level of utilization of OBS networks while maintaining acceptable blocking probability. We consider bufferless optical burst switching (OBS) networks with deflection routing, in which channel reservation is used to avoid instability, and with realistically high number of channels per ...

Dynamic service differentiation in OBS networks
2007 Fourth International Conference on Broadband Communications, Networks and Systems (BROADNETS '07), 2007In this paper we propose an edge-to-edge closed-loop scheme to provide Quality-of-Service (QoS) in Optical Burst Switching (OBS) networks. Performance parameters for each burst flow are exchanged by a feedback message called Service Control Message (SCM) which is processed only at the edge/ingress nodes.

Enhanced congestion management in OBS networks
2017 IEEE AFRICON, 2017Due to the bufferless nature of optical burst switched (OBS) networks, contention/congestion in the core network can quickly lead to degradation in overall network performance at moderate to high traffic levels due to heavy burst losses. Several approaches have been explored to address this problem, notably measures that would minimize burstification ...

Service differentiation scheme in OBS networks
Photonic Network Communications, 2007In order to achieve service differentiation, especially loss differentiation, in optical burst switching (OBS) networks, we propose a dynamic fiber delay line (FDL) partitioning algorithm, which divides FDLs into several groups over a feed-forward output buffering architecture.
