“…In contrast to our results, the ATM Forum has proposed a uniform distribution for the cell delay variation (CDV) which seems conservative compared to the data observed in our experiments. Also, in [5] it was shown that the 1-point CDV and the end-to-end delay distribution could be fitted accurately to a Gamma distribution over a wide range of network parameters. As noted above, the Gamma distribution did not fit our observed data.…”

“…Another quantity of interest is the queuing delay incurred which can be determined from the end-to-end delay by subtracting the known propagation delay, BBT delay and the switch latencies. In [5], using simulation, it was shown that the end-to-end cell queuing delay never exceeded the range [0, 60] cells or [0, 164.1 µs] at even very heavy loads. This article concluded that the 1 ms limit on the range of the cell delay variation placed by the ATM Forum and ITU-T seemed to be rather high.…”

“…For instance, if the peak rate requirement of a traffic stream increases as it traverses the network due to interference with other traffic, downstream switching nodes may have to reserve more bandwidth for this stream than upstream nodes. Related work on ATM traffic characterization uses stochastic process analyses, simulation, and, more recently, measurements from operational networks (primarily ATM LANs) [1][2][3][4][5]. A significant difference between our work and most other measurementbased projects is that our measurements were conducted in a wide area environment with emphasis on the ATM cell level traffic characteristics.…”

As asynchronous transfer mode (ATM) networks move from the design phase to the deployment phase, several theoretical assumptions and hypotheses made in the research literature can be evaluated. Experimental validation and verification is an essential component in the overall development of any novel technology. In this article the authors report the results of several controlled experiments measuring the transport of traffic in a wide area ATM network: the very high-speed Backbone Network Service (vBNS). We illustrate how the characteristics of a tagged traffic stream change as the traffic traverses the network. Also, IP applications traffic is characterized at the ATM level. Lastly, we comment on the validity of theoretical assumptions often made in the research literature.

Mapping the end to end QoS requirements into link QoS requirements is an important step for resource allocation of connection oriented services. The problem of the QoS partitioning has been addressed in literature and proved to be NP complete. Different algorithms are proposed to solve the problem of single end-to-end QoS metric. However, these algorithms are near optimal or heuristic algorithms and solve the QoS partitioning problem for single QoS metric. In this paper, we propose a novel optimal partitioning algorithm which is capable of partitioning the end to end QoS requirement for multiple QoS metrics, additive and multiplicative, simultaneously. Extensive simulation verified the effectiveness of the algorithm compared to two QoS partitioning algorithms. The results show that the proposed algorithm outperforms the other two algorithms for loose and stringent QoS requirements and over different path lengths.
