INFINIBAND ADAPTIVE CONGESTION CONTROL ADAPTIVE MARKING RATE

摘要

A device and a method for optimizing data transfer rate in an InfiniBand fabric is provided where a various number of transmitting devices aim data packets to a single receiving device or through a common link. The method which is implemented in an InfiniBand switch includes marking of packets in a rate corresponding to centrally configured marking rate, determination of the current number of data flows between the input ports and the output port of the switch and marking the data packet with Forward Explicit Congestion Notification according to an adaptive value of marking rate which depends on the initial value of the marking rate and is inversely proportional to the number of data flows.
