Abstract
A method of controlling data flow in a network includes detecting a congestion condition in the network, sending a congestion message to one or more nodes upstream of the congestion condition, learning address information of one or more nodes pertaining to the congestion condition, sending another congestion message containing these learned MAC addresses and, via the nodes receiving the congestion message with the MAC addresses, controlling a flow of data associated with the learned address information from the congestion message. The learned address information may be the MAC address of a destination node to which the data is flowing towards or a MAC address pair of the nodes between which the data is flowing.

Method for data flow control in a network, comprising:
- detecting a congestion condition in the network;
- and
- sending a congestion message to one or more nodes upstream of the congestion condition;
- said congestion message adapted to enable an upstream node to learn address information of at least one node associated with the congestion condition to enable thereby the control of data flows in a manner tending to reduce the congestion condition.
A computer readable medium containing a program which, when executed, performs an operation of controlling data flow in a network comprising:
- detecting a congestion condition in the network;
- and
- sending a congestion message to one or more nodes upstream of the congestion condition;
- said congestion message adapted to enable an upstream node to learn address information of at least one node associated with the congestion condition to enable thereby the control of data flows in a manner tending to reduce the congestion condition.
Apparatus for controlling flow of data in a network comprising:
- means for detecting a congestion condition in the network;
- and
- means for sending a congestion message to one or more nodes upstream of the congestion condition;
- said congestion message adapted to enable an upstream node to learn address information of at least one node associated with the congestion condition to enable thereby the control of data flows in a manner tending to reduce the congestion condition.
