All the previous delay analyses of TDMA have been based on the assumption that either the interarrival times of the traffic is exponential or the message lengths are geometrically distributed. This paper presents a generalized model in which the above assumptions are relaxed. This model allows us to compute the exact performance characteristics in closed forms for the mean and the variance of the queue size and the message delay for the TDMA. The model is used to define and compare five bursty traffic distributions. These distributions are used to study their effects on the buffer size and the end-to-end delay for the Mars Regional Network.","PeriodicalId":272859,"journal":{"name":"Proceedings.

Multi-lateral cache designs such as the Assist, Victim, and NTS cache have been shown to perform as well as or better than larger, single structure caches. Unlike current cache simulators, mlcache (an event-driven, timing-sensitive simulator based on the Latency Effects cache timing model) can evaluate a variety of multilateral cache configurations. It was developed to help designers in the middle of the design cycle decide which cache configuration would best meet the performance needs of the target processor. It can easily model various cache configurations by using its library of cache state and data movement routines. We use the SPEC95 benchmarks to illustrate how mlcache can be used to compare the performance of several different data cache configurations.","PeriodicalId":272859,"journal":{"name":"Proceedings.

This paper explores, through empirical simulation, the QOS, network utilization, and statistical characteristics of the aggregate traffic resulting from multiple independent MPEG video streams. In addition, the simulation results are compared against several recently-derived theoretical results for self-similar network traffic. Three main results are evident from our experiments. First, moderate statistical multiplexing gain can be achieved when multiplexing multiple self-similar streams. Second, video multiplexing is extremely sensitive to traffic phasing effects and to heavy-tailed frame size distributions. Finally, the theoretical approach considered (Norros (see IEEE Journal on Selected Areas in Communications, vol.13, no.6, p.953-62, 1995) effective bandwidth formulation) appears promising but requires fine-tuning to be practical for call admission and network dimensioning.","PeriodicalId":272859,"journal":{"name":"Proceedings.

A new scheme for TCP congestion control: smooth-start and dynamic recovery 一种新的TCP拥塞控制方案:平滑启动和动态恢复

The new scheme includes two parts: (I) the smooth-start algorithm, which replaces the slow-start algorithm at the start of a TCP connection or after a retransmission timeout, and (2) the dynamic recovery algorithm, which replaces the fast recovery algorithm to recover packet losses when a TCP connection is congested. Both algorithms require modifications only to the sender side of the TCP implementation. Simulation is used to evaluate the performance of the algorithms. The simulation experiments are conducted using the ns simulator to facilitate comparisons with Tahoe, Reno, New-Reno, SACK, and FACK TCP. The simulation results show that the new scheme performs at least as well as SACK and FACK TCP, which in turn consistently outperform TCP Tahoe and Reno. Furthermore, the implementation of the new scheme is simpler than that of SACK and FACK.","PeriodicalId":272859,"journal":{"name":"Proceedings.

These protocols, such as the time-based and the distance-based protocols, try to minimize the system overhead for locating a mobile user in the network. The contribution of this paper to develop a novel mathematical model to analyze these protocols and at the same time, make a general model to capture many important movement features. In this paper, we propose to use the transient analysis method to predict the location of a mobile user and the accuracy of the prediction of the location of a user can be enhanced. By applying the transient analysis to evaluate the time-based and the distance-based protocol, it gives us more insights in the performance of these protocols under different movement configurations. Last but not least, our model is general enough such that it provides a general framework to analyze other location update protocols in cellular networks.","PeriodicalId":272859,"journal":{"name":"Proceedings.

Many replacement policies used in cache management, we notice, is restricted in that they consider only one (or few) parameters to decide which video to kick out of the cache, like the frequency of requests, or the size of objects. We look at a new cache management algorithm which is higher-performing since it considers, besides the time of requests and the past request history of a video, the video characteristics which viewers, generally, have a bias for. However, the viewer's bias and the objects' characteristics vary with time and location. We enhanced the cache management technique by making it adaptive to the different characteristics viewers and videos have at different times and places.","PeriodicalId":272859,"journal":{"name":"Proceedings.

To address this problem, we have developed the IP Benchmark (IPB), a benchmark program that synthetically generates traffic to simulate the network activity of common Internet applications. It measures the performance experienced by the simulated applications, and expresses that performance in terms of application-specific metrics. After presenting same details of the design and implementation of IPB, we show how we use it to measure HTTP performance along various long-delay, lossy ATM links, such as might be found in satellite or wireless ATM environments. These links themselves are simulated by using a BBN Long Link Emulator which adds delays and errors to local-area OC-3 links.

Aggregate statistics of cache performance can be useful for comparison, but they give us little insight into how to improve the design of a particular component. We propose a different approach to cache analysis-viewing caches as filters-and present two new metrics for analyzing cache behavior: instantaneous hit rate and instantaneous locality. We demonstrate how these measures can give us insight into the reference pattern of an executing program, and show an application of these measures in analyzing the effectiveness of the second level cache of a particular memory hierarchy.","PeriodicalId":272859,"journal":{"name":"Proceedings.
