Traac models are at the heart of any performance evaluation of telecommunications networks. An accurate estimation of network performance is critical for the success of broadband networks. Such networks need to guarantee an acceptable quality of service (QoS) level to the users. Therefore, traac models need to be accurate and able to capture the statistical characteristics of the actual traac. ...

This article discusses the architecture, control protocols, and coordination mechanisms used in today’s multimedia Ž . Ž . conferencing standards for ISDN Integrated Services Data Network and IP Internet Protocol networks. Specifically, the Ž . ITU-T’s International Telecommunication Union – Telecommunication Standardization Sector H.320 and H.323 multimedia conferencing standards are discussed...

Problems for intellectualisation for man-machine interface and methods of self-organization for network control in multi-agent infotelecommunication systems have been discussed. Architecture and principles for construction of network and neural agents for telecommunication systems of new generation have been suggested. Methods for adaptive and multi-agent routing for information flows by reques...

The digital revolution holds great promise for prosperity and progress. However, the Information Society evolution is supported through the telecommunication networks deployment. The high cost of such infrastructures forces the companies to focus their efforts in the profitable society sectors. For that, the promotion of performances to bridge the digital divide between rural and urban areas ap...

The rapid evolution of network services demands new paradigms for studying and designing networks. In order to understand the underlying mechanisms that provide network functions, we propose a framework which enables the functional analysis of telecommunication networks. This framework allows us to isolate and analyse a network function as a complex system. We propose functional topologies to v...

It should be noted that there are widely varying definitions of the term ̀ agent'. This document will not attempt to provide an authoritative definition, but will mention some qualities shared by most agents and raise some of the inherited problems associated to these concepts. A software agent is a piece of software which acts to accomplish tasks on behalf of its user. Many agents are based on ...

This article reviews the literature on networks and, more specifically, on the development of community telecommunication networks. It strives to understand the collaboration needed for innovative projects such as intelligent networks. Guided by a change management framework, collaboration within a community network is explored in terms of the formation and performance phases of its development...

This paper presents a general method for the diagnosis of large systems, such as telecommunication networks. Because of the size of the system, the model we use is decentralized. In order to increase the efficiency of the diagnosis, the method combines two basic techniques of diagnosis: diagnosers and simulation-based techniques. We propose the construction of diagnosers based on local behavior...

As interlibrary loan (ILL) becomes an increasingly used resource sharing mechanism for the exchange of books and periodicals, libraries have embraced new technologies to better manage ILL activities. While many efficiencies have been gained through the use of computers and telecommunication networks, the proliferation of telecommunication options, ILL systems and non-standard message formats ha...
