CONGESTION CONTROL IN DATA NETWORKS

摘要

A method of modifying transmission of packets over a network path comprises operating a processor to: transmit packets over the network path; determine, based on a number of unacknowledged packets transmitted over the network path, whether a congestion event has occurred, wherein an unacknowledged packet is a transmitted packet for which no acknowledgement has been received; and responsive to detecting a congestion event, operating a processor to modify the number of unacknowledged packets transmitted by a multiplicative factor βi, wherein the multiplicative factor βi is proportional to a ratio of a first time value to a second time value, the first time value being indicative of a minimum time required for a packet to be transmitted over the network path and the second time value being indicative of a current time required for a packet to be transmitted over the network path.
