Abstract
Techniques disclosed herein provide an approach for providing throughput resilience during link failover when links are aggregated in a link aggregation group (LAG). In one embodiment, failure of a link in the LAG may be detected, and a Transmission Control Protocol/Interact Protocol (TCP/IP) stack notified to ignore packet losses and not perform network congestion avoidance procedure(s) for one round-trip timeout (RTO) period. In a virtualized system in particular, a virtual switch may be configured to generate events in response to detected link failures and notify TCP/IP stacks of a hypervisor and/or virtual machines (VMs) of the link failures. In turn, the notified TCP/IP stacks of the hypervisor and/or VMs may ignore packet losses and not perform network congestion avoidance procedure(s) for one RTO period.
