    In shortest path (SP) routing, only the shortest path po between a source-and-destination pair is used to route traffic. However, if all data is 'selfishly' routed through po, degradation of network performance due to unregulated traffic along po may result. Recent studies show that multipath routing approaches that observe loop-free invariant (LFI) conditions impr... View full abstract»

  • Long-run performance analysis of a multi-scale TCP traffic model

    Publication Year: 2004, Page(s):251 - 257
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (326 KB)

    The long-run queueing performance of a multi-scale TCP traffic model, the HOO model, is analysed. Since the model links the multi-scale behaviour with practical traffic elements and approximates TCP traffic very well, the analysis is expected to provide insights into the physical interpretation of multi-scale traffic and to give useful results for performance prediction. To derive a meaningful sol... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (322 KB)

    The data rate of a digital communication system depends on the bandwidth available to the system. Nyquist's theorem states that it is possible to transmit without intersymbol interference (ISI) at 2B symbols/s, given a bandwidth of B Hz. At present, no commercially available system achieves this Nyquist efficiency. It is well known that under certain orthogonality conditions, data transmission usi... View full abstract»

  • On-demand packet discard scheme for TCP over ATM-UBR service

    Publication Year: 2004, Page(s):190 - 196
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (311 KB)

    The performance of the TCP over ATM networks is investigated. A TCP packet is segmented into multiple ATM cells at the sending node and reassembled at the receiving node. When congestion occurs, the ATM switch may drop some of the cells. If one or more cells of a TCP packet are dropped, the TCP packet is said to be corrupted. A corrupted packet will be discarded at the receiving node. Transmitting... View full abstract»

  • Analysis of cross issues between QoS routing and /spl mu/-mobility protocols

    Publication Year: 2004, Page(s):258 - 262
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (320 KB)

    The current modus operandi of different proposed architectures for all-IP mobile and wireless networks is commonly based on the assumption of best-effort routing and per-class (DiffServ) or per-flow (IntServ) treatment of IP traffic. At the same time, emergence and promotion of QoS routing as an embedded network feature seems orthogonal to the deployment of current /spl mu/-mobility protocols. The... View full abstract»

    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (371 KB)

    Voice conferencing is an essential block of any multimedia system used for collaborative work, as voice is shared by all participants. Floor control is mission-critical here and has been investigated by many to ensure fair resource sharing; yet fixing the number of floors has remained an open problem. A conferee (participant in a conference) can speak only after acquiring the floor. To allow impro... View full abstract»
