Abstract
A controller for controlling the flow of messages in a communication system to a node, in which the controller comprises a rejection monitor for monitoring the rate of message rejection by the node; an admit monitor for monitoring the rate of messages to the node passed by the controller; and control means for controlling the rate at which messages to the node are passed on the basis of the monitored rejection rate and the monitored admit rate so that the rejection rate tends towards a target value. The control means limits the maximum rate at which the messages are passed to a control value.
Claims22
A controller for controlling the flow of messages in a communication system to a node, in which the controller comprises
- a rejection monitor for monitoring the rate of message rejection by the node;
- an admit monitor for monitoring the rate of messages to the node passed by the controller;
- and
- control means for controlling the rate at which messages to the node are passed on the basis of the monitored rejection rate and the monitored admit rate so that the rejection rate tends towards a target value.
A controller arranged in use to control the flow of messages in a communication system to more than one node and comprising:
- a rejection monitor for monitoring the rate of message rejection by each of the nodes;
- an admit monitor for monitoring the rate of messages to each of the nodes passed by the controller;
- and
- control means for controlling the rate at which messages to the nodes are passed on the basis for each node of the monitored rejection rate and the monitored admit rate for that node so that the rejection rate for each node tends towards a target value.
A method for controlling the flow of messages in a communication system to a node, including the steps of
- monitoring the rate of message rejection by the node;
- monitoring the rate of messages to the node passed by the controller;
- and
- controlling the rate at which messages to the node are passed on the basis of the monitored rejection rate and the monitored admit rate so that the rejection rate tends towards a target value.
A method for controlling the flow of messages in a communication system to a node from a plurality of sources, including the steps of
- monitoring the rate of message rejection by the node of messages from each source;
- monitoring the rate of messages from each source passed to the node;
- and
- controlling the rate at which messages to the node from each source are passed on the basis of the monitored rejection rates and the monitored admit rates so that the rejection rate tends towards a target value.
A method for controlling the flow of messages in a communication system to more than one node including the steps:
- monitoring the rate of message rejection by each of the nodes;
- monitoring the rate of messages to each of the nodes passed by the controller;
- and
- controlling the rate at which messages to the nodes are passed on the basis for each node of the monitored rejection rate and the monitored admit rate for that node so that the rejection rate for each node tends towards a target value.
