Thus, in the face of uncertainty regarding the true nature of the system and traffic traversing the system, robustness entails maximising the performance of the network across the entire range of possibilities. We investigate standard robust prediction techniques for the design of ABR rate control mechanisms, but, while these optimize for the case with the greatest uncertainty, the system performance can suffer significantly for other cases. By introducing a spectral density comparison term to the entropy, we arrive at a performance measure which achieves robustness in the sense of maintaining high performance under uncertainty. Performance also includes computational efficiency, and various long-range dependent models are compared with regards to the robustness of the system, allowing the model with the least computational expense to be selected.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks.

However shaping alters the characteristics of a traffic flow and is in danger of degrading individual flow's QoS, particularly where no per flow connection admission control is used, unless the source is able to respond to the shaping operation. The IETF's Assured Forwarding Specification defines a multi precedence level, probabilistic packet dropping mechanism to give controlled sources such as TCP the ability to respond to congestion. In this paper we propose combining this with a suitable shaping mechanism to enable controlled sources to respond to shaping operations. While we believe this to be generally applicable, we develop the idea in the specific context of differentiated services over an ATM link where traffic shaping at the ATM level is required to exploit ATM's QoS capability, for example using VBR. An experimental implementation is described, based on commercial equipment, which is used to demonstrate the essential features of an Assured Forwarding PHB with three levels of drop precedence. In particular we show that sources of traffic with different precedence levels can, simultaneously, be in different modes of the TCP control algorithm.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks.

This algorithm can improve the fairness characteristics under a wide range of network conditions and is robust in terms of the setting of its control parameters. It can be used in a distributed architecture, as can the core-stateless fair-queuing (CSFQ) algorithm, so it is applicable to large-capacity backbone routers. Through a detailed evaluation, this paper identifies and clarifies the fairness degradation problem in the CSFQ algorithm. CS-RED was derived to solve this problem by incorporating congestion notification in the RED algorithm. Evaluation of the CS-RED algorithm by computer simulation and comparison of the fairness characteristics in networks using either the CS-RED or the CSFQ algorithm showed that a higher level of fairness is achieved with the CS-RED algorithm under a wide variety of network conditions without degrading link utilization. The treatment necessary to prevent unresponsive flows in best effort networks is also discussed. We have found that a more general treatment, rather than the penalty box, can be used with the CS-RED algorithm.","PeriodicalId":122125,"journal":{"name":"10th IEEE Workshop on Local and Metropolitan Area Networks.
