Comparative analysis of power consumption in asynchronous wavelength modular optical switching fabrics
(Elsevier, 2011-04-02)Next-generation optical routers will be designed to support the flexibility required by Future Internet services and, at the same time, to overcome the power consumption bottleneck which appears to limit throughput scalability ... -
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 ... -
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 ... -
Optical core networks research in the e-Photon-ONe+ project
(2009)This paper reports a summary of the joint research activities on Optical Core Networks within the e-Photon-ONe+ project. It provides a reasonable overview of the topics considered of interest by the European research ... -
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 modeling of QoS differentiation in optical packet switching via FDL access limitation
(Springer New York LLC, 2017)We present an exact analytical model for single-wavelength quality of service (QoS) differentiation in a two-class optical packet switch. In this system, QoS differentiation is achieved by limiting the set of fiber delay ... -
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 ... -
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 ... -
Shared-per-wavelength asynchronous optical packet switching: a comparative analysis
(Elsevier, 2010-03-23)This paper compares four different architectures for sharing wavelength converters in asynchronous optical packet switches with variable-length packets. The first two architectures are the well-known shared-per-node (SPN) ... -
State aggregation-based model of asynchronous multi-fiber optical switching with shared wavelength converters
(Elsevier, 2013)This paper proposes new analytical models to study optical packet switching architectures with multi-fiber interfaces and shared wavelength converters. The multi-fiber extension of the recently proposed Shared-Per-Input-Wavelength ... -
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 ... -
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 ...
