The issue of providing deterministic delay guarantee using the Dynamic Priority Queueing (DPQ) scheme to support multiple connections at a single server queue is investigated. The novelty of our approach lies in that the delay bound is derived without making any assumptions about the traac characteristics of the connections. We rst show that the DPQ server provides a delay bound comparable to t...

The discovery of a fractal phenomenon in computer network and compressed packet video traac has added a new dimension to teletraac modeling and analysis. But some of the recent research eeort on the modeling and analysis of the fractal phenomena have generated results that are seemingly confusing or contradictory. The goal of this study is to correctly digest the recent contributions, examine t...

A set of companion documents describe an architecture for providing integrated services over low-bitrate links, such as modem lines, ISDN B-channels, and sub-T1 links [1, 2, 3, 4]. The main components of the architecture are: a set of real-time encapsulation formats for asynchronous and synchronous low-bitrate links, a header compression architecture optimized for real-time flows, elements of n...

It has become clear in the last few years that there is a trend towards integrated digital services. P d e l to the development of public Integrated Services Digital Network (ISDN) is service integration in the local area (e.g. a campus, a building, an aircraft). The types of services to be integrated depend very much on the specific local environment. However, applications tend to generate dat...

considering a) that satellites operating in the fixed-satellite service play an important role in providing reliable international digital communications; b) that, therefore, satellite performance must comply with performance objectives as specified by ITU-T Recommendation I.356-B-ISDN ATM layer cell transfer performance; c) that in defining performance criteria, it is necessary to take into ac...

purpose: with the entrance of information and communication technologies (ict) in the context of libraries and with the development of electronic services, the evaluation of these kinds of services has become more important. the purpose of this study was to evaluate the quality of electronic services at the libraries of ferdowsi university of mashhad (fum) form the point of view of librarians –...
