    ATM networks are today operational, both as backbones for existing LAN technologies and as commercial wide-area multiservice networks. Still, in the early deployment of multi-site ATM networks, a number of difficulties have arisen out of the differences between the service definitions in local ATM networks and long distance carrier networks. In particular, the adaptation of LAN emulation protocols... View full abstract»

    Gaussian traffic models for high speed communication networks have received an increasing amount of attention. There are some puzzling and counter-intuitive features to deal with, such as negative traffic. However, on the plus side, the central limit theorem can be invoked to argue that traffic will become closer to Gaussian as more and more of it is aggregated together. The Gaussian model has a n...

    This paper proposes a new parallel control scheme with feedback control (PCFC) for ABR services in ATM networks. The information from a source is split into a number of streams for delivery over separate parallel connections. At the receiver, the original information is reconstructed using the cells received from the parallel connections. Traffic splitting of PCFC achieves two advantages for the n... View full abstract»

    The broadband integrated service digital network (B-ISDN) will have to offer real-time communication services; that is, it will have to transport information with performance guarantees. In this paper, we propose a communication system for real-time applications using a 155 Mbits/sec ATM (asynchronous transfer mode) switch. This system is based on an intelligent communication board for PCs (person... View full abstract»

    To evaluate the provision of data service support in ATM networks, complex interactions between different protocol layers have to be considered. These interactions are originated by concurrent operation of flow control mechanisms at several layers. In this paper, we propose a new modelling approach for performance evaluation of these kinds of system. The proposal is based on a modular and object-o... View full abstract»

  • IP switch over ATM LAN emulation (IP-ExpressTM)

    Publication Year: 1998, Page(s):454 - 458
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (400 KB)

    ATM is a widespread technology and most of the traffic it carries is from legacy LANs or generated by LAN-oriented software such as TCP/IP. Hence the importance of ATM Forum's LAN emulation protocol (LANE) and multi-protocol over ATM (MPOA) to allow bridging and routing of this traffic over an ATM network. In this article we focus on routing LAN flows among several emulated LANs. A novel technique... View full abstract»

    The ATM service category UBR is intended for non-real-time applications that do not require guaranteed QoS commitments. With additional, relatively inexpensive control functions such as packet discard schemes, UBR could become a cost-effective alternative for the transmission of data traffic; offering a straightforward and flexible solution as opposed to nrt-VBR and GFR that applies stricter traff...

    We tackle the problem of characterizing variable bit rate MPEG sources in order to allow for efficient video multiplexing in asynchronous transfer mode (ATM) networks. We show that the gamma distribution is a good tool for modeling the aggregate traffic of homogeneous as well as heterogeneous VBR MPEG sources. Therefore, we propose the use of simple and intuitive video descriptors based on the gam... View full abstract»

    For an ATM network, the VBR (variable bit rate) service category is used to accommodate TCP/IP traffic. In an international ATM network with large propagation delay, higher TCP throughput can be obtained by use of the window scale option. In order to accommodate TCP traffic with the window scale option effectively, it is required to select optimum values of VBR parameters, i.e. SCR (sustainable ce... View full abstract»

    The role of call admission control (CAC) in high-speed networks is to maintain the network utilization at a high level, while ensuring that the quality of service (QoS) requirements of the individual calls are met. We propose a generic dynamic call admission scheme for VBR and ABR traffic whose aim is to reduce the blocking rate for VBR calls at the expense of a higher blocking rate for ABR calls....

    For ATM networks, VBR, ABR and UBR are effective solutions to accommodate TCP/IP based LAN traffic. To obtain a high quality networking provision for TCP traffic it is important to select either ATM guaranteed or best effort service parameter values to clarify the interaction between the TCP flow control mechanism and the usage parameter control (UPC) function of the ATM switch.

    ATM networks often carry other popular communication protocols such as TCP/IP. LAN emulation techniques, with LANE and MPOA being the most prominent ones, make it possible to support existing applications, but do not take advantage of many ATM capabilities. Furthermore, such server-based solutions often suffer from a single point of failure problems. PNNI augmented routing (PAR), based on private ... View full abstract»

    The process of routing, that is, the handling of Internet protocol (IP) packets at layer 3 (the network layer), is a potential bottleneck in large intranets and the public Internet. Asynchronous transfer mode (ATM) provides a hardware capability of switching cells at very high speeds at layer 2 (the link layer). A number of schemes for supporting IP over ATM hardware have emerged in recent years. ... View full abstract»

    The ATM Forum's PNNI (private network node interface) standard specifies a flooding mechanism to distribute topological state information amongst nodes participating in a PNNI network. While the flooding mechanism provides robust topology distribution, we show by simulation, that it can disproportionately overload lower-bandwidth links and, due to its inherent redundancy, can generate considerable...

    Available bit rate (ABR) service may be used by applications which expect cell loss guarantees, but can control their data dynamically as demanded by the network. The introduction of variable bit rate (VBR) background traffic makes ABR capacity variable. A video aggregation system can adapt the traffic from several Moving Picture Expert Group (MPEG) sources as a bundle to the ABR on the network, o... View full abstract»

    The limited energy stored in the battery-operated mobile equipment leads to the development of protocols that preserve it as much as possible. Existing MAC protocols for wireless communications, such as GSM, IEEE 802.11, and HIPERLAN, allow the mobile terminals to operate in different power-saving modes. We briefly present the case for the existing radio LAN, describe the WATM MAC protocol, and in... View full abstract»
