The weighted-rate guarantee is necessary to available-bit rate (ABR) service models. This fact has motivated the wide study of weighted max-min (WMM) fair-fate allocation for ABR traffic. However, the combination of close-loop feedback control with the WMM algorithm has not appeared in the previous research. In this paper, a practical WMM fair-rate allocation model is proposed. This scheduling scheme combines and integrates congestion avoidance using proportional control (CAPC) and weighted max-min fair-rate allocation. In the system under analysis, a new weighted traffic scheduler is introduced. This model is designed to achieve higher utilization and also bounded delay for ABR traffic flow control.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Measurements cover a time period of about one month, and we propose a method to gain confidence about the significance of the statistical parameters computed from the collected traffic traces, in order to reduce the risk that the extracted statistical features depend on a particular measurement session. The last part of the work reports some simulation studies, aiming to infer the statistical features that have a major impact on queueing performance.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The GFR enables provision of cost-effective ATM services for IP-based data communications. There are two implementation alternatives for the GFR, which are FIFO and per-VC queuing. It is difficult to provide consistent services when both schemes exist in a network, because they show different characteristics for TCP/IP traffic. Taking into account this issue, this paper discusses GFR service policy that is fair for all the users. In order to clarify GFR service characteristics, the performance of our developed FIFO-based GFR circuit is demonstrated. Then the relationship between fairness and charging system is discussed and a hybrid charging scheme is proposed.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

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 future server rate, estimated from the currently available information. The objective of this paper is to find an optimal time t/sub s/<T for switching the service from interfering traffic to CBR traffic. This switching of the scheduler from one traffic to another traffic takes into account the stochastic variation of the server rate. Three cases of variation of the source rate are considered, namely: (1) when the server rate is a constant; (2) when the server rate jumps randomly between two values; and (3) when the variation of server rate follows a diffusion process. In all three cases, this paper shows that there exists an optimal switching time t/sub s/ after which the low-priority CBR traffic can be scheduled for service. The maximum delay and the cell loss rate are determined.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The so-called, pre-assigned backup VP (virtual path) restoration algorithm has been proved to have a fast restoration from failure, but its success greatly depends on how the traffic is distributed and how the spare capacity is dimensioned over the network. In this paper, we address the problem of spare capacity resource control, in order to guarantee complete restoration, improving the survivability performance of the self-healing algorithm. Centralized and distributed controls are used as methods for backup VP assignment. The performance of each method and the management of spare resources are investigated by simulation. The results show that the centralized method has higher efficiency, in resource utilization, than the distributed one. Furthermore, the spare resource control can achieve good fairness performance in resource utilization.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The traffic parameters were numerically evaluated by computer simulation and the VC multiplexing effect was also evaluated using a simple connection admission control algorithm.

In principle, the cross-path switch can support both multicast and multirate traffic and now we add the capacity of supporting multimedia traffic in it. In this paper, we develop a model to study the performance guarantees in a cross-path switch. Based on this model, we derive a set of deterministic bounds on propagation delay as well as backlogs at the switch on a per-connection basis. The results show that due to the quasi-static nature of the routing scheme implemented at the central stage, data traffic always becomes more bursty after passing through the cross-path switch. This leads to the criteria for the design of the route assignment algorithm.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.
