Rate based flow control with bandwidth information

Rate based flow control with bandwidth information

The ATM Forum has chosen the rate-based approach for ow control of ABR (Available Bit Rate) traac in ATM. It is based on a reactive approach whereby the transmission rate of ABR sources can be adapted to the available bandwidth at a bottleneck link. The ATM forum has speciied the behavior of the source and destination, as well as the manner in which feedback information (on the available bandwi...

Rate-Based Flow Control

On high-speed networks, the round trip delay from source to intermediate node and back is relatively large compared with packet transmission times; thus, the window-based method of flow control does not react quickly enough to prevent congestion and large delay. An alternative method is to employ a rate-based flow control scheme, in which each node is assigned a maximum rate and an average rate...

Rate-based Ow Control with Delayed Information

Multiuser rate-based flow control

Flow and congestion control allow the users of a telecommunication network to regulate the traffic that they send into the network in accordance with the quality of service that they require. Flow control may be performed by the network, as is the case in asynchronous transfer mode (ATM) networks (the available bit rate (ABR) transfer capacity), or by the users themselves, as is the case in the...

Integrated Control of Connection Admission, Flow Rate, and Bandwidth for ATM Based Networks

We consider the combined control problem of connection admission, flow rate, and bandwidth allocation (capacity, service-rate) under nonstationary conditions. A fluid flow model in state variable form describes the time varying mean behaviour of Available Bit Rate (ABR) traffic, which competes with Guaranteed Traffic for network resources. Using nonlinear control we derive an integrated control...
