    Emerging high-speed networks will support a number of real-time services required by distributed multimedia applications, such as video-on-demand. To support these services, appropriate routing procedures should be used; upon receipt of a request to open a new connection with certain quality of service (QoS) requirements, an appropriate routing procedure calculates an "optimal" route (with respect...

    Several efficient reliable broadcast protocols have been developed and implemented on broadcast LANs. To enhance the amount of bandwidth available per node on a shared media LAN, such as 10 Mb/s Ethernet, there is a rapidly growing usage of LAN switches to interconnect several independent LAN segments to form an Extended LAN (E-LAN). The existing reliable broadcast protocols may be inefficient in ... View full abstract»

    If the reliability provided by the network is lower than that requested by the application, the error and flow control systems in the end nodes must make up for the difference. While most applications use retransmission based schemes to recover lost data, ARQ based closed loop techniques may not be suitable for many new applications. Time sensitive information requiring no loss of data would const... View full abstract»
