Abstract
In a technique for performing flow control in a wide-area network, a user-specified flow control message such as a Pause message is provisioned at a first node, and a user-specified flow control message filter is provisioned at a second node coupled to the first node. At the first node, the availability of a buffer for data received from the second node is monitored, and in response to a predetermined availability condition, the provisioned flow control message is sent to the second node. In a Pause/Resume protocol, the buffer may be monitored for an Almost Full condition, and the flow control message may be a Pause message indicating that the first node should suspend transmission. The second node compares messages from the first node against the flow control message filter. Upon detecting the flow control message from the first node, the second node takes a predetermined flow control action with respect to the transmission of data to the first node. In the case of a Pause/Resume protocol, the flow control action may be to stop transmission for a specified period.
