    We describe the process of introducing new equipment for the telecommunications networks of the former USSR, taking into account our personal experience. First, it is important that we are dealing mainly with local switching, so the examples discussed are mainly from this particular field. Today the former Soviet Union is still a united country from the point of view of telecommunications (and tel... View full abstract»

    The purpose of state- and time-dependent routing (STR) is to achieve high performance despite unpredictable real-time traffic fluctuations, with minimum changes to existing switching software and operations systems. STR uses an appropriate combination of the two kinds of control, centralized and distributed. The article gives an overview of STR and its advanced call-level routing, describes the cu...

    Dynamic network evolution achieves network performance improvement and cost reduction by taking advantage of new advanced technologies being introduced into the network to achieve greater network flexibility and efficiency. The author describes the evolution of dynamic networks, with examples drawn from the AT&T DNHR network deployed in the '80s and RTNR network deployed in the '90s. Dynamic t... View full abstract»

    According to Lithuania's Master Plan, further development of the country's telecommunications infrastructure must be concentrated on modern digital technology, most of it produced in Western countries. The Master Plan is divided into three parts. First, it is a short term plan that covers the development of telecommunication systems with high priority, and covers the period through the end of 1997... View full abstract»

    The current status of Russia's telecommunications infrastructure does not correspond to the country's increasing demands. The creation of a commercial digital overlay network is apparently the only possible solution to provide modern telecommunications services. This article describes the following aspects of the evolution of telecommunications in Russia: a classification of the main specific feat... View full abstract»

    Presents an overview of the efforts of the 13 participating carriers that comprise the Worldwide Intelligent Network (WIN) Dynamic Routing Group to introduce dynamic routing internationally. The authors propose that the introduction of dynamic routing could be accomplished in stages, starting with the deployment of flexible overflow routing for bilateral networks. Then the authors examine performa... View full abstract»

  • A fuzzy control approach for adaptive traffic routing

    Publication Year: 1995, Page(s):70 - 76
    Cited by:  Papers (14)

    The application of fuzzy control to adaptive traffic routing in telephone networks is investigated. The authors use, on one hand, the properties of fuzzy control techniques and adaptive routing, on the other hand, to derive a routing system that is robust and efficient. They analyze the impact of various availability indicators on performance, which indicates that the choice of a suitable indicato... View full abstract»

  • Dynamically controlled routing in networks with non-DCR-compliant switches

    The authors investigate the deployment of a state-dependent call routing scheme in a network where only a fraction of the switches can fully support it. The state-dependent routing scheme considered is dynamically controlled routing (DCR). Not all switches are assumed to be capable of supporting the feature that DCR requires. For switches that cannot support DCR, several alternative routing scheme... View full abstract»

    The article deals with the integrated design and analysis of a telecommunications network to achieve specified levels of survivability under various failure modes and conditions. The main goal of the article is: given a criterion for network survivability, develop a unified theory for network planning at different “layers” of the network, and for coordinated restoration methods after a...
