Method for controlling congested network flow
View Patent ↗A buffer size for a router configured to receive packets transmitted through a communications network is temporarily increased at a time instant corresponding to an onset of congestion of the router for a time period that may be approximately equal to a round-trip packet time in the network. The increase in buffer size may be accomplished by providing an auxiliary storage area for packets that would otherwise be stored in a queue at the router, for example an auxiliary storage area associated with a physical storage device external to the router.
1. A method, comprising temporarily increasing an effective serving rate, for a router configured to receive and transmit packets in a communications network at a time instant corresponding to an onset of congestion of the router, and thereby increasing the number of packets that a source, which provides packets to the router, is allowed to transmit into the communications network, wherein the effective serving rate is increased for a time period comprising a round-trip time interval for a packet transmitted in the network.
2. The method of claim 1 wherein increasing the effective serving rate comprises providing an auxiliary storage area for packets that would otherwise be stored in a queue at the router.
3. The method of claim 2 wherein the auxiliary storage area is associated with a physical storage device external to the router.
