Mills","doi":"10.1109/ICC.1998.685196","DOIUrl":"https://doi.org/10.1109/ICC.1998.685196","url":null,"abstract":"Many previous studies on network traffic demonstrate that long-range dependence (LRD) is a ubiquitous property of traffic both in a local area network (LAN) and a wide area network (WAN). So the performance of the network should be dominated by this property. The packet round-trip delay is an important measurement of network performance. We present evidence that LRD exists in packet round-trip delays. This discovery has serious implications for understanding the impact on network performance of LRD network traffic, and the design of transport control protocols for special applications, i.e., of teleconferencing. Statistical analyses show that the complementary probability distribution of packet round-trip delays decays more slowly than at an exponential rate; this fact probably justifies the studies on the prediction of the queue length distribution with LRD network traffic. We also tentatively use a multi-queueing system to interpret the existence of LRD in the packet round-trip delay process, which we believe is caused by the LRD of Internet traffic.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.

There have been two main approaches for connection restoration: dynamic approach and backup approach. We discuss the trade-offs between the two approaches and propose a new restoration mechanism that centers around the concept of the virtual backup network, which provides backup path sharing as well as spare bandwidth sharing. The proposed mechanism can take advantage of the two existing approaches together with special interests in resource efficiency and routing flexibility.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.

It also provides efficient mechanisms for hosts to join and leave multicast groups. The problem of supporting macro and micro level host mobility in the Internet involves similar issues of location independent addressing, address translation, packet forwarding and location management of mobile hosts. We have developed a new approach called MSM-IP for supporting host mobility using IP multicasting as the sole mechanism for addressing and routing packets to mobile hosts. In this paper, we present the performance of UDP and TCP over MSM-IP, and compare it with their performance over Mobile-IP. Our analysis shows that our approach is very effective in supporting seamless mobility for both handoffs and interface changes within and across networks. The performance of both UDP and TCP are better when used with MSM-IP than with Mobile-IP. We briefly explain our approach, and present performance results, and explain the results.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.

It creates a random-governed modulo-1 sequence which is smoothed and adapted to a given marginal distribution. The smoothing is realized by the so-called stitching function, which is demonstrated to have a crucial influence on the shape of the resulting simulated time series and its autocorrelation function. The main aim of this paper is to show how the choice of suitable (generalized) stitching functions provides a very attractive way to simulate sample paths that are visually indistinguishable from the given time series. The rather intuitive procedure is illustrated for the cases of periodic network utilization and the modeling of MPEG frame sizes.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.

As the cell travels the inter-network enroute to the destination ATM user node interface (UNI), the CRC parity is checked and the cell is dropped or passed to the next ATM hop accordingly. A standard go-back-N ARQ technique is applied end to end while a lost-cell concealment technique cooperates below as a forward error correction mechanism that also operates end to end. The error detection and correction techniques above are applied to connectionless oriented traffic. The hierarchy of the error control technique above is presented and the end-to-end user performance in terms of net throughput and reliability is analyzed. We investigate the interactive effects of the channel and ATM signalling parameters on the system performance, with particular emphasis on the design of the error control scheme.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.

This multiaccess methodology without any specific frame concept can guarantee worst-case delay of CBR and VBR traffic sources and therefore can guarantee the QoS of delay-sensitive, jitter-sensitive CBR and VBR traffic sources. The derived delay bound of specific traffic only depends on its own traffic parameters. This impressive characteristic benefits bandwidth allocation and consequently results in a simple call admission control policy. Other important issues, including a simple link control mechanism for CBR and VBR over unreliable channels, are also suggested.","PeriodicalId":218354,"journal":{"name":"ICC '98. 1998 IEEE International Conference on Communications.
