Analysis of continuous feedback Markov fluid queues and its applications to modeling Optical Burst Switching
(IEEE, 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 ... -
Congestion window-based adaptive burst assembly for TCP traffic in OBS networks
(Springer, 2010-06-29)Burst assembly is one of the key factors affecting the TCP performance in optical burst switching (OBS) networks. When the TCP congestion window is small, the fixed-delay burst assembler waits unnecessarily long, which ... -
Dimensioning shared-per-node recirculating fiber delay line buffers in an optical packet switch
(Elsevier, 2013)Optical buffering based on fiber delay lines (FDLs) has been proposed as a means for contention resolution in an optical packet switch. In this article, we propose a queuing model for feedback-type shared-per-node recirculating ... -
Dynamic threshold-based assembly algorithms for optical burst switching networks subject to burst rate constraints
(Springer, 2010-04-17)Control plane load stems from burst control packets which need to be transmitted end-to-end over the control channel and furtherprocessed at core nodes of an optical burst switching (OBS) network for reserving resources ... -
Effect of burst length on loss probability in OBS networks with void-filling scheduling
(Bilkent University, 2006)Optical burst switching (OBS) is a new transport architecture for the next generation optical internet infrastructure which is necessary for the increasing demand of high speed data traffic. Optical burst switching stands ... -
Exact analysis of single-wavelength optical buffers with feedback markov fluid queues
(Optical Society of America, 2009-10-15)Optical buffering via fiber delay lines is used for contention resolution in optical packet and optical burst switching nodes. This article addresses the problem of exactly finding the blocking probabilities in an asynchronous ... -
Flow control and service differentiation in optical burst switching networks
(Bilkent University, 2005)Optical Burst Switching (OBS) is being considered as a candidate architecture for the next generation optical Internet. The central idea behind OBS is the assembly of client packets into longer bursts at the edge of an ... -
Joint resource and network scheduling with adaptive offset determination for optical burst switched grids
(Elsevier, 2010-11-24)Optical burst switching (OBS) is a promising technology for optical grids with short-lived and interactive data communication requirements. On the other hand, burst losses are in the nature of the OBS protocol and these ... -
Packet loss analysis of synchronous buffer-less optical switch with shared limited range wavelength converters
(IEEE, 2007)Application of synchronous optical switches in Optical Packet/Burst switched networks is considered. The shared per node architectural concept, where wavelength converters are shared among all input and output channels, ... -
Performance study of asynchronous/ synchronous optical burst/ packet switching with partial wavelength conversion
(Bilkent University, 2006)Wavelength conversion is known to be one of the most effective methods for contention resolution in optical packet/burst switching networks. In this thesis, we study various optical switch architectures that employ partial ... -
Rate-controlled optical burst switching for both congestion avoidance and service differentiation
(Elsevier, 2005)Optical Burst Switching (OBS) has recently been proposed as a candidate architecture for the next generation optical Internet. Several challenging issues remain to be solved to pave the way for the OBS vision. Contention ... -
Retrial queuing models of multi-wavelength FDL feedback optical buffers
(Institute of Electrical and Electronics Engineers, 2011)Optical buffers based on Fiber Delay Lines (FDL) have been proposed for contention resolution in optical packet/burst switching systems. In this article, we propose a retrial queuing model for FDL optical buffers in ... -
Stochastic analysis of finite population bufferless multiplexing in optical packet/burst switching systems
(Denshi Jouhou Tsuushin Gakkai,Institute of Electronics Information and Communication Engineers, 2007)In this letter, we study the blocking probabilities in an asynchronous optical packet/burst switching system with full wavelength conversion. Most of the existing work use Poisson traffic models that is well-suited for an ... -
A survey of quality of service differentiation mechanisms for optical burst switching networks
(Elsevier, 2009-09-26)This paper presents an overview of Quality of Service (QoS) differentiation mechanisms proposed for Optical Burst Switching (OBS) networks. OBS has been proposed to couple the benefits of both circuit and packet switching ... -
Using multiple per egress burstifiers for enhanced TCP performance in OBS networks
(Springer New York LLC, 2009)Burst assembly mechanism is one of the fundamental factors that determine the performance of an optical burst switching (OBS) network. In this paper, we investigate the influence of the number of burstifiers on TCP performance ... -
Wavelength converter sharing in asynchronous optical packet/burst switching: an exact blocking analysis for markovian arrivals
(IEEE, 2006-12-11)In this paper, we study the blocking probabilities in a wavelength division multiplexing-based asynchronous bufferless optical packet/burst switch equipped with a bank of tuneable wavelength converters dedicated to each ...
