Journal ArticleDOI
TL;DR: If a hop-by-hop inter-domain routing protocol allows unconstrained route selection at a domain, the protocol may be susceptible to route oscillations, and ways to prevent or avoid persistent oscillations in general topologies are evaluated.

Journal ArticleDOI
Robert J. Hall1
TL;DR: An approach to feature combination and interaction detection via foreground/background models, which allows expressing features as augmentations to the behavior of a base model, and classifies interactions into three categories, based on how they can be detected, and describes implemented tools which can detect interactions from the three categories.

TL;DR: Simulation results demonstrate that under the same link speed and network topology, network nodes employing the DiAserv architecture have substantial performance improvement over the current Best EAort (BE) Internet architecture for multimedia streaming applications.

Journal ArticleDOI
TL;DR: A comprehensive approach for IEPCs as complex information spaces will be presented and a concept for organizing information within IE PCs, which goes beyond simple keywords and multimedia, will bePresented.

Journal ArticleDOI
TL;DR: A coherent framework of interoperable testing is developed in which the notions of interoperability, interoperability testing, interoperable test case and interoperabilityTest architecture are interrelated and a systematic interoperability test suite derivation method based on the framework is developed.

Journal ArticleDOI
TL;DR: This evaluation evaluated actual DS mechanisms provided by Cisco routers, which supports flow-specific QoS specification, immediate and advance reservation, and online monitoring and control of both individual resources and heterogeneous resource ensembles.

Journal ArticleDOI
TL;DR: The effect of stream multiplexing on delay and jitter-sensitive traffic is analyzed through an experimental approach and two different scheduling algorithms are considered: Priority Queuing (PQ) and Weighted Fair Queued (WFQ).

Journal ArticleDOI
TL;DR: Results show that routing algorithms based on a Markov decision theoretic framework yield better performance than least-load path routing (LLP) without incurring any significant increase in computational complexity.

Journal ArticleDOI
TL;DR: An investigation into the distribution issues surrounding the design and implementation of virtual market places (ViMPs) focuses on the structuring of the information space describing the services and products, and its distribution between the providers and the market place mediator.

Journal ArticleDOI

Journal ArticleDOI
TL;DR: Phantom, a simple constant space algorithm for rate-based flow control, converges fast to a fair rate allocation while generating a moderate queue length and can be gradually introduced into installed-based TCP networks.

Journal ArticleDOI
TL;DR: VIDOS is a Java-based server–client video management system that permits one to customize a personal version of any downloadable digital video file over the Internet or local intranet and can improve corporate and personal efficiency by speeding network transfers and cutting disc storage requirements.

Journal ArticleDOI
TL;DR: This paper presents a call admission control (CAC) scheme for traffic with self-similar behaviour based on the notion of effective bandwidth that satisfies the quality of service requirements of the source, expressed in terms of buffer overflow probability, while taking into account the long-range dependence property of the traffic through the Hurst parameter.

Journal ArticleDOI
TL;DR: This paperribes serious attacks against IP control and management protocols with an accent on the ICMP protocol, as well as some of the well-known vulnerabilities of the inter-domain routing protocols.

Journal ArticleDOI
TL;DR: Analysis of an optical packet switch making use of fiber delay-lines to resolve output packet contentions and equipped with a set of tunable wavelength converters shared among the input lines shows that the number of converters needed to maintain the packet loss probability is much lower than that needed by the switches proposed in literature.

Journal ArticleDOI
TL;DR: The suitability of H.323 technology and currently available products to support teleteaching services is investigated, based on experience gained during a related deployment at the University of Athens.

Journal ArticleDOI
TL;DR: This paper shows through simulations that deflection routing is an effective technique for packet-switching wavelength routed optical networks with irregular meshed topologies and multiple path routing (MPR) as the deflection rule mitigates the blocking of packets substantially in cross-connected all-optical networks leading to a significant reduction in hardware volume and cost.

Journal ArticleDOI
TL;DR: In 1998, the Fifth International Workshop on Feature Interactions [1] sponsored the first-ever Feature Interaction Detection Contest as mentioned in this paper, where the goal was to compare different automated tools for detecting feature interactions from the feature requirements.
