چکیده

A rate-based congestion control algorithm regulates cell emission rate of source end systems based on feedback information from the network. It was standardized by the ATM Forum for application to an ABR (Available Bit Rate) service class. In the standard, two types of congestion notification methods of the switch are specified: EFCI marking and explicit-rate marking. In this paper, we focus on explicit-rate marking switch. We propose our enhancements on a recently proposed switch algorithm called as the max-min scheme. The main objective of our enhancements is to control the queue length of the switch for preventing cell loss and achieving full link-utilization. We show effectiveness of our switch algorithm by simulation experiments.

An efficient rate allocation algorithm for ATM networks providing max-min fairness

We describe a new algorithm for rate allocation within the individual switches of an ATM network implementing a rate-based congestion control algorithm for Available Bit-Rate (ABR) traac. The algorithm performs an allocation in (1) time, allowing it to be applied to ATM switches supporting a large number of virtual circuits. When the total available capacity or the requests of the individual co...

Max-Min Fair Rate Control of ABR Connections with Nonzero MCRs

Traac sources that do not have intrinsic temporal characteristics are expected to be transported over ATM networks using the Available Bit Rate (ABR) service. These sources are amenable to reactive ow control and are expected to use bandwidth left over after servicing the guaranteed QoS services (CBR and VBR). Fair allocation of the available bandwidth to competing ABR connections is based on t...

Dynamics of an Explicit Rate Allocation Algorithm for Atm Networks

In this paper we study the performance of an explicit rate allocation algorithm for ATM networks using the available bit-rate (ABR) class of service. We examine the behavior of ABR traac with simple cell sources, and demonstrate that the allocation algorithm is fair and maintains network eeciency in a variety of network conngurations. We also study the behavior of TCP/IP sources using ABR servi...

Rate-based Scheme for Atm Flow Control

ATM is representative of the connection-oriented resource provisioning class of protocols. The ATM network is expected to provide end-to-end QoS guarantees to connections in the form of bounds on delays, errors and/or losses. Performance management in ATM network depend upon different parameters. ABR flow control is one of the important parameter for performance management. In this paper, we sh...
