Throughput resilience during link failover

A non-transitory computer-readable storage medium containing a program which, when executed by one or more processors, performs operations for providing throughput resilience during link failover, the operations comprising:

• determining that a link in an aggregation of links has failed, wherein packet flows on the failed link are transferred to one or more other links in the aggregation of links that are active;
• notifying a protocol layer originating the packet flows that the link failed;
• and
• disabling network congestion avoidance procedure(s) by the protocol layer on the packet flows for a predefined period of time.

A system, comprising:

• a processor;
• a plurality of network interface controllers (NICs), wherein the NICs are grouped together in an aggregation of links;
• and
• a memory, wherein the memory includes a program executable in the processor to perform operations for providing throughput resilience during link failover, the operations comprising:
• determining that a link in the aggregation of links has failed, wherein packet flows on the failed link are transferred to one or more other links in the aggregation of links that are active.
• notifying a protocol layer originating the packet flows that the link failed, and
• disabling network congestion avoidance procedure(s) by the protocol layer on the packet flows for a predefined period of time.
• 20, The system of claim 19, wherein the predefined period of time is one round-trip timeout (RTO) period beginning from when the link failure is determined.
