    After a brief introduction to the theory of Petri nets, the MTP (multicast transport protocols) for the distributed network management system is presented. The authors designed the group communication protocol which has low protocol-message overhead and efficiency. The atomic and reliable group communication protocol designed in the paper guarantees that each message sent to a group is delivered t... View full abstract»

    Since functional reduction is based on relation instance maps from a set of output places of transition to the corresponding set of input places in an adjacent transition, the concept of composition is formalized as a new transition, and is compounded from two joinable transitions with the merging of the places of two transitions after eliminating common places. This method has one handicap as a s... View full abstract»

  • A multicast protocol for network management system

    Publication Year: 1995, Page(s):364 - 368
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (535 KB)

    A new group communication protocol has been proposed and implemented for a distributed network management system. To reduce the protocol overhead, distributed and hierarchical approaches have been introduced: the group management function has been split into three functional entities. The first one is the local group manager (LGM) which manages one or more member(s) in one host. The second one is ... View full abstract»

    The video on demand (VOD) service can be implemented in a variety of ways called service policies. This paper investigates the characteristics of three distinct service policies, namely, on demand single cast, on demand multicast and phase multicast. The performance of the different service policies are evaluated and it was found that the on demand single cast policy is suitable for specialised vi... View full abstract»

    We introduce two novel connection control protocols for high-speed networks, which we call the efficient reservation virtual circuit (or ERVC) protocol and the ready-to-go virtual circuit (or RGVC) protocol. Both protocols have been developed for the 40 Gbit/s fiber-optic ATM-based Thunder and Lightning network, currently being designed and built at UCSB. The ERVC protocol, which is designed for c...

    Probability distribution of the channel holding time in cellular mobile communication is found using cell residence time distribution under general mobility conditions. It is shown that cell residence time distribution can be specified by the generalized gamma distribution. Based on the result it is shown that the negative exponential distribution is a good approximation for the channel holding ti... View full abstract»

    The ability to hold real-time collaborative document and multimedia conferencing has now become a reality, especially with the availability of high bandwidth networks like ATM and FDDI. However, to hold such a conference interactively on the more common networks like Ethernet may place great stress on available bandwidth. Therefore, it will be of great advantage, both, from the cost point of view,... View full abstract»

    This paper discusses a simulation of the Estelle specifications of the ISO transaction processing protocol using the Estelle development toolset (EDT). The Estelle specification is first checked for syntactical and semantical errors using an Estelle translator and once the specification is error-free, an intermediate form (IF) is produced. A C-code generator is then used to translate the IF into C... View full abstract»

    A variety of video-phone systems have begun to appear in the consumer market. The quality of the images generated by these systems is severely affected by the bandwidth restriction of the twisted cable pair. Typically, some of these systems operate with a transmission bit rate less than 19.2 kbps. In comparing different systems with respect to image quality, one finds it useful to assess the quali...

    The handover algorithm of digital cellular mobile systems often require the successive signal samples to be averaged over a period of time. The averaging time is a critical parameter in eliminating the unnecessary handover attempts, and has to be carefully determined for a given mobile environment. Among the factors that influence this parameter are the degree of shadowing present in the mobile en... View full abstract»
