Performance Evaluation of Rate-Based Congestion Control Algorithm with Explicit Rate Switch Algorithms for Bursty Traffic

چکیده
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 been proposed and evaluated by many researchers, but they consider only persistent traffic; that is, bursty traffic has not been considered. In this paper, we evaluate the performance of four switch algorithms — binary switch, ERICA, Max-Min and EMMS — for bursty traffic through simulation experiments. 英文 key words Rate-Based Congestion Control Algorithm, Bursty Traffic, Binary Switch, ERICA Scheme, Max-Min Scheme, Enhanced Max-Min Scheme

Several algorithms have been proposed for the switch behavior for congestion control of Available Bit Rate (ABR) services. Schemes such as the Enhanced Proportional Rate Control Algorithm (EPRCA) and the Dynamic Max Rate Control Algorithm (DMRCA), which use the queue length as congestion indicator to make a simple approximation of the fair share converge to the actual fair share, have become po...

An ATM (Asynchronous Transfer Mode) is a promising technology for realizing B-ISDN (Broadband Integrated Services Digital Network) that can transfer many types of multimedia information. In ATM-based networks, all information is transferred by dividing into fixed-size packets (called as cells). The ATM network is a connection-oriented network by virtue of a notion of virtual circuits called VPs...

In this paper we investigate the performances of the EFCIbased (Explicit Forward Congestion Indication) and ER-based (Explicit Rate; EPRCA in particular) algorithms for the rate-based flow control of the ABR (Available Bit Rate) traffic in an ATM network. We consider the case of multiple switches in tandem. We present several definitions of a bottleneck, and provide conditions that determine wh...
