Contention resolution and burst assembly scheme based on burst segmentation in optical burst switching networks

Optik, 2013
Abstract In this paper, contention resolution scheme based on burst segmentation and deflection routing in the core node and composite burst assembly scheme at the edge node are proposed. In the core node, contention is resolved through incorporating prioritized burst segmentation with deflection routing scheme.

Providing QoS Using Burst Composite Assembly Algorithm in Optical Burst Switching Networks

2006 International Conference on Communication Technology, 2006
In optical burst switching (OBS), the performance of networks is directly affected by the process of burst assembly at edge nodes. In this paper, to provide high quality of service, a novel assembly mechanism called burst composite assembly (BCA) is proposed, which combines the best of the algorithm of fixed-assembly-period (FAP) and adaptive- assembly-

A novel burst assembly method for energy saving in burst switching networks

TENCON 2012 IEEE Region 10 Conference, 2012
Future growth of the Internet is likely to be constrained by its own energy consumption. As shown in recent studies, by adopting burst switching technologies, energy consumption of the core network could be reduced. In this study we first analyse the relationship between burst size, arrival rate, and energy consumption of a core router port in a burst ...

Prioritized burst segmentation and composite burst-assembly techniques for qos support in optical burst-switched networks

IEEE Journal on Selected Areas in Communications, 2003
We address the issue of providing quality-of-service (QoS) in an optical burst-switched network. QoS is provided by introducing prioritized contention resolution policies in the network core and a composite burst-assembly technique at the network edge. In the core, contention is resolved through prioritized burst segmentation and prioritized deflection.

Research Paper on Burst Assembly Modeling for Optical Burst Switched Network

2014 Fourth International Conference on Communication Systems and Network Technologies, 2014
Optical burst formation is aggregation of incoming packets for same destination, which are switched together. Optical Burst Switch (OBS) allow variable burst formation time and burst sizes which can be so that network resources will be used optimally.

A study of adaptive burst assembly mechanism in optical burst switch networks

SPIE Proceedings, 2004
As a promising switching paradigm, Optical Burst Switch (OBS) was proposed for optical networks showing more efficient and shorter delay than traditional circuit switching, and it is more feasible than optical packet switching. In OBS, burst assembly is one of the critical technologies, and will significantly affect the performance of networks. In this

The Effect of Burst Assembly on Performance of Optical Burst Switched Networks

2004
We evaluate and compare the performance of timer-based and threshold-based assembly algorithms in Optical Burst Switching networks. Results including burst blocking probability, mean packet delay and link utilization at the ingress node are presented from both simulations and two theoretical models.

Adaptive data burst assembly in OBS networks

2016 Sixth International Conference on Digital Information Processing and Communications (ICDIPC), 2016
To perform an Optical Burst Switching (OBS) network, a lot of challenges are faced that have to be solved. The edge node has to manage burst offset time and burst assembly technique. The core node has to reserve resources to send the data burst, schedule the control packet and data burst and contention resolution strategy. In this paper, we discuss the

Round-robin burst assembly and constant transmission scheduling for optical burst switching networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
In this paper, we propose a round-robin burst assembly and constant burst transmission for optical burst switching (OBS) network. In the proposed method, ingress edge node has multiple buffers where IP packets are stored depending on their egress edge nodes, and bursts are assembled at the buffers in round-robin manner. Moreover, bursts are transmitted

An optical burst reordering model for a time-based burst assembly scheme

2008 5th International Conference on Broadband Communications, Networks and Systems, 2008
In optical burst switching networks, contention resolution schemes as well as contention avoidance schemes reduce the burst loss probability. These schemes delay the burst delivery and may change the burst arrival sequence. In this paper we present an analytic burst reordering model and derive analytically the impact of a time-based burst assembly ...
