Client-server synchronization and buffering for variable rate multimedia retrievals
(1996)We consider the use of large buffers and feedback as a mechanism to maintain loosely coupled synchronization between a multimedia server and a client. The multimedia stream is modeled as a fluid flow through rate controlled ... -
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 calculation of blocking probabilities for bufferless optical burst switched links with partial wavelength conversion
(2004)In this paper, we study the blocking probabilities in a wavelength division multiplexing-based asynchronous bufferless optical burst switch equipped with a bank of tuneable wavelength converters that is shared per output ... -
H∞-Performance analysis of robust controllers designed for AQM
(American Automatic Control Council, 2003)It has been shown that the TCP connections through the congested routers with the Active Queue Management (AQM) can be modeled as a nonlinear feedback system. In this paper, we design H∞ robust controllers for AQM based ... -
Impact of scalability in video transmission in promotion-capable differentiated services networks
(2002)Transmission of high quality video over the Internet faces many challenges including unpredictable packet loss characteristics of the current Internet and the heterogeneity of receivers in terms of their bandwidth and ... -
Performance analysis of two-level forward error correction for lostcell recovery in ATM networks
(1995)The major source of errors in B-ISDN/ATM systems is expected to be buffer overflow during congested conditions, resulting in ATM cell losses which degrade the quality of service. It has been shown by many authors that the ... -
A reordering-free multipath traffic engineering architecture for DiffServ-MPLS networks
(Institute of Electrical and Electronics Engineers Inc., 2003)We propose a novel traffic engineering architecture for IP networks with multiprotocol label switching (MPLS) backbones. In this architecture, two (primary and secondary) label switched paths (LSPs) are established among ... -
Robust controller design for AQM and H∞-performance analysis
(Springer, 2005)Active Queue Management (AQM) has recently been proposed in [1] to support the end-to-end congestion control for TCP traffic regulation on the Internet. For the purpose of alleviating congestion for IP networks and providing ... -
Short-range wireless communications and reliability
(Cambridge University Press, 2011)Even though there is no universally accepted definition, short-range wireless communications typically refers to a wide variety of technologies with communication ranges from a few centimeters to several hundreds of meters. ... -
Solving the single server semi-Markov queue with matrix exponential kernel matrices for interarrivals and services
(2006)Markov renewal processes with semi-Markov kernel matrices that have matrix-exponential representations form a superset of the well-known phase-type renewal process, Markovian arrival process, and the recently introduced ... -
Star p-hub center problem and star p-hub median problem with bounded path lengths
(2012)We consider two problems that arise in designing two-level star networks taking into account service quality considerations. Given a set of nodes with pairwise traffic demand and a central hub, we select p hubs and connect ...
