Abstract:
1. A method for processing data, the method comprising: transmitting a probe from a source node to a destination node in response to said source node receiving one or more congestion notification frames from said destination node, said probe comprising a departure timestamp that indicates a departure time of said probe; calculating, at said source node, a destination packet arrival rate at said destination node based on an arrival timestamp inserted into another probe by said destination node; comparing, at said source node, a sending rate (Rs) of one or more data packets at said source node and said destination packet arrival rate at said destination node; and rate limiting, at said source node, said sending rate of said one or more data packets at said source node based on said comparing of said sending rate at said source node and said destination packet arrival rate at said destination node, wherein said comparing at said source node is performed over a number of sample periods, and said sending rate Rs at said source node is calculated according to a following equation: where B new is a number of bytes transmitted in a network flow since arrival of a previous probe, B old is a number of bytes transmitted in said network flow up to transmitting said probe, Ts new is said departure timestamp and Ts old is a departure timestamp of a previous probe.
