    Highly flexible and survivable networks can be built by allocating optical carriers of heterodyne systems. The basic features of heterodyne systems are reviewed, especially the use of multicarriers, tunability, and selectivity. Then specific application areas that may benefit from flexible multicarrier allocation schemes are discussed. Examples are taken from the RACE Phase II project R2065, coher... View full abstract»

    Erbium-doped fiber amplifiers are a major breakthrough for soliton communication. Most of the difficult problems preventing soliton communication recently were solved using erbium-doped optical fiber amplifiers (EDFAs). Progress in optical soliton communication has been very rapid, since the invention of the 1.48 μm laser diode pumped EDFA, mainly because of its great potential for high-sp... View full abstract»

    In the last five to ten years, simulation has been used with greater frequency to analyze communications networks, due in part to the increased number of networks in existence and to their greater complexity. The authors define the types of simulation software that are available for network analyses and also discuss desirable features for such products. They then present brief descriptions of seve...

    Simulating trunk and signaling networks allows planners to examine network survivability, capacity, and the impact of new service introductions. The challenge is to accurately predict network performance and behavior for a rapidly changing environment, and for the very large networks that are encountered in the public telephone system. This paper describes the discrete event modeling of SS7 signal... View full abstract»

    Simulation packages do not provide an effective infrastructure for reusing models, but reuse will become a reality as more tools provide database capabilities and other features. The article describes a framework of requirements needed to support simulation model reusability and summarizes the most critical areas for improvement in the current generation of graphical simulation environments....

    As new communications services evolve, professionals must create better models to predict system performance. The article provides an overview of computer simulation modelling for communication networks, as well as some important related modelling issues. It gives an overview of discrete event simulation and singles out two important modelling issues that are germane to extant and emerging network... View full abstract»

    Avoiding recopying of user data as it is passed between protocol layers helps break the protocol-execution bottleneck. The authors use a use a simple pointer-variable updating technique in the sending phase of their refined buffer cut-through scheme. Binary tree traversal is not required. Time is saved in allocating (and later deallocating) buffers for storing usually short data transfer protocol ... View full abstract»

    LAN emulation offers a best-effort, connectionless, packet transfer service at the MAC sublayer, implemented on top of a connection-oriented ATM network LAN emulation using switched virtual connections requires address resolution to locate the destination end station followed by connection establishment to the resulting ATM address. Address resolution may be implemented by a broadcast technique or... View full abstract»
