Patent ID: 8248930

Claim:
A method comprising: receiving, via a first interface, a packet flow of data packets from a first network for forwarding to a node of a second network, the second network employing a protocol for managing congestion and the first network not employing any protocol for managing congestion; receiving, at a second interface, a notification from the second network that indicates that congestion is affecting communication with the node of the second network, wherein the protocol for managing congestion employed by the second network defines a given bitrate for sending at least one first packet in the packet flow to the node of the second network; responsive to the notification, calculating a first time and a second time to satisfy the given bitrate, enqueuing the packet flow into a process-controlled queue at the first time; dequeuing the at least the one first packet in the packet flow from the queue at the second time; and sending the at least one first packet of the packet flow to the node of the second network via the second interface.
