Robustness of Rate-Based Congestion Control Algorithm with Binary-Mode Switch in ATM Networks

چکیده
A rate-based congestion control algorithm has been developed and standardized in the ATM forum for ABR service class. Even though the performance of the rate-based congestion control algorithm heavily depends on the selection of those control parameters, the selection method of parameters is not shown in the standard. In this paper, by extending our previous work, appropriate settings of rate-control parameters in the various circumstances are investigated. We first analyze the dynamical behavior of the rate-based congestion control for multiple groups of ABR connections with different propagation delays. Next, we evaluate the effect of CBR/VBR traffic on ABR connections. 1QJ8key words ABR Service Class, Rate-Based Congestion Control, Control Paramters, Binary-Mode Switch

Performance of Rate-based Congestion Control Algorithm with Binary-mode Switch in Atm Networks
A rate-based congestion control algorithm has been developed and standardized in the ATM forum for ABR service class. In the standard, the behavior of end systems is specified by several rate-control parameters such as RIF (Rate Increase Factor) and RDF (Rate Decrease Factor). Even though the performance of the rate-based congestion control heavily depends on a selection of these control parame...

A rate-based congestion control algorithm regulates cell emission processes of source end systems according to feedback information from the network in order to utilize network resources. Although behavior of source and destination end systems have been standardized by the ATM Forum, operation algorithm of intermediate ATM switches are left to manufacturers. Many types of switch algorithms have...
متن کاملStability Analysis of the Rate-Based Congestion Control Algorithm for ABR Service Class in ATM Networks
A rate-based congestion control algorithm is a feedback-based flow control mechanism for ABR (Available Bit Rate) service class. When the operation of the rate-based congestion control algorithm becomes unstable, it would cause several problems; fairness among connections is deteriorated, and QoS (Quality of Service) of ABR service class becomes unpredictable. In this paper, we analyze the dyna...

متن کاملMax-Min Rate Control Algorithm for Available Bit Rate Service in ATM Networks
The deenition of Available Bit Rate (ABR) service has been the focus of the recent activities of the ATM Forum. The Forum has adopted rate-based schemes as the standard for congestion control of ABR services, and has accepted Enhanced Proportional Rate Control Algorithm (EPRCA) as the recommended algorithm for the switch behavior. In this paper, we propose a new binary control algorithm, called...
