    Publication Year: 1999, Page(s):435 - 440
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (380 KB)

    This paper proposes a message-based signaling middleware for the B-ISDN control plane. This middleware differs significantly from other RPC-based proposals, such as CORBA and Java, in the systematic use of specific signaling mechanisms rather than a general-purpose protocol, such as RPC or GIOP. Multimedia applications require access to the services of a middleware layer through the use of functio... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (676 KB)

    This paper presents a new distributed scheduling architecture for wireless ATM networks. Usually, in WATM scheduling architectures, a fixed order is defined among the different connections through their ATM service category (CBR, VBR, ABR, UBR). We argue that although this static priority is easier to implement, this type of precedence is not necessarily a good choice for the MAC layer. The MAC la... View full abstract»

  • Optimal service schedule for CBR traffic in a high speed network

    Publication Year: 1999, Page(s):509 - 514
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (364 KB)

    This paper studies the optimal service schedule of CBR traffic when the server rate is modelled according to a Markov process. The CBR traffic is mixed with traffic of another session (interfering traffic) which might be either CBR or VBR (variable bit rate) or both. The CBR traffic can suffer a maximum delay of T. The scheduler must decide which session must be scheduled for service based on futu... View full abstract»

  • Multicast ATM switch architecture based on a recursive method

    Publication Year: 1999, Page(s):475 - 480
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (392 KB)

    This paper proposes simple architecture to support multicasting in ATM switches. The proposed architecture consists of a self-routing switch which enables us to copy cell and line interfaces with a header conversion part. Our finding is that multicast can be realized by the method as follows; (1) copying cells in the switch; (2) recurring the copied cells from output ports to input ports; (3) chan...

    Numerous research has been done on modeling the traffic flows in a multiservice network. An alternative proposal was made by Addie et al. (1998). The authors argued that because the central limit theorem can be applied to heavy traffic processes, therefore as more traffic is aggregated together through the sharing of a transmission link, the aggregated traffic will weakly converge to a Gaussian pr...

    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (420 KB)

    A multi-stage switching architecture is a key technology for building a high-speed ATM switching system. An effective way to make a multi-stage switch nonblocking is to use cell-based routing. However, cell-based routing may cause cell-sequence disorder at the output of the switching fabric. This paper proposes a hierarchical cell-sorting (HCS) switch architecture, which is a nonblocking multi-sta... View full abstract»
