Abstract
A method for providing resilient load balancing in a system comprising a first processing unit, a second processing unit, a first active load balancer and a second active load balancer is disclosed. A first set of packet flows may be mapped to the first active load balancer and a second set of packet flows may be mapped to the second active load balancer. The first set of packet flows may include a first packet flow. In some embodiments, the method includes: (a) storing, by the first processing unit, a set of state information associated with the first active load balancer, the set of state information comprising state information associated with a first session associated with the first packet flow; (b) receiving, by the first processing unit, information indicating that the first active load balancer is inoperable; and (c) in response to receiving the information indicating that the first active load balancer is inoperable, transmitting, from the first processing unit to the second active load balancer, the state information associated with the first session.
