Patent number: 11765082Abstract: Systems and computer program products for performing retransmission of data packets over a network. A node receives a data packet with a source and a destination address. The data packet is sent along a network path to the destination address, and information associated with the data packet is sent to a controller node that is independent of the network path. A controller receives information associated with a data packet from any forwarder node within a plurality of forwarder nodes each monitoring communications along separate communications paths. An indication of a receipt acknowledgement for the data packet is received from a second forwarder node that is separate from the first forwarder node and the controller node. The receipt acknowledgement is correlated with the data packet and based on the correlating, data associated with retransmission processing of the data packet is deleted.Type: GrantFiled: July 27, 2018Date of Patent: September 19, 2023Assignee: International Business Machines CorporationInventors: Thai Franck Le, Erich M.
