    This paper presents a trace-driven analysis of IP over ATM services from a user-perceived quality of service standpoint. QoS parameters such as the sustained throughput for transactional services and other ATM layer parameters such as the burstiness (MBS) per connection are derived. On the other hand, a macroscopic analysis that comprises percentage of flows and bytes per service, TCP transaction ... View full abstract»

    In principle, the interaction of RSVP and ATM should allow us to benefit at the IP level from some features coming from the ATM layer. The most interesting feature is the native support of end-to-end quality of service provided by the ATM. On the other hand, there are issues that must be clarified to define a working solution for the interworking. For example, the possible overlapping between the ... View full abstract»

    The differentiated services (DiffServ) architecture promises the provision of QoS-enabled networks by following a simple approach that eliminates scalability concerns and which can be implemented and managed in large networks. However, for end-to-end QoS an appropriate signaling scheme, like the resource reservation protocol (RSVP), should be supported. In this combined approach, signaling message... View full abstract»

    Virtual path and virtual channel management are very important to ATM networks. By using the VP concept the virtual layout of the network can be modified to improve the utilization of the network. With large bandwidths freely available the existing VP management strategies need to be modified. One of the problems that may arise as a result of this is that the number of connections supported by the... View full abstract»

    Cell level analysis of ATM networks by means of simulation requires an accurate model for traffic sources. We present a simple model for TCP over ATM traffic sources in an ATM LAN, which captures the fundamental characteristics of the behaviour of TCP in this environment. The model was developed by extensive statistical analysis of numerous traffic traces recorded in an ATM testbed. Simulated traf... View full abstract»

    In this paper we propose approaches for shortcutting of IP flows over large ATM networks. With large ATM networks we mean that the single physical ATM network is logically structured into multiple logical ATM subnetworks. Shortcutting across such large, logically structured ATM networks is a technique to avoid network layer processing as much as possible by maximizing the switched path across the ...

  • A hybrid data/header interleaving strategy for wireless ATM networks

    A header interleaving strategy was proposed to reduce the cell loss probability for wireless ATM networks. Such a strategy spreads each header bit over the entire data field. Lots of burst errors on cells will be transformed into a single-bit error on the header which can be easily corrected by the HEC (header error correction) field. Since each corrected cell may also contain incorrect payload, a... View full abstract»

    Driven by increasing competition, service providers target customers to deliver value added IP services like “voice over IP” (VoIP) or “virtual private networks” (VPN) over their networks. Thus, IP has become the de facto convergence layer which integrates all types of traffic within a heterogeneous network infrastructure. On the one hand IP was originally designed for best...
