A load balancing system that utilizes a dynamic method for updating a load balancer's pool of targets (e.g., a dynamic method for adding newly available targets to the pool of targets and/or removing from the pool of targets a target that is no longer accepting new connections). Advantageously, this dynamic method does not require periodic monitoring of each of the targets in the pool of targets.

Method, apparatus and computer program product for updating load balancer configuration data

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.

Systems and methods for scalable and resilient load balancing

A method in a gateway router is described. The method includes receiving traffic with a destination of a virtual internet protocol (VIP) address corresponding to a scalable VIP appliance; selecting a point-to-point VIP tunnel associated with the VIP address, wherein the point-to-point VIP tunnel encapsulates a point-to-point link between the gateway router and the scalable VIP appliance; separating one or more packets within the traffic; classifying each of the one or more separated packets based on one or more indicators of the one or more separated packets; and forwarding each of the one or more separated packets to one of one or more IP tunnels based on the classification of each of the separated packets, wherein the one or more IP tunnels are connected to the scalable VIP appliance and wherein the one or more IP tunnels comprise a forwarding tunnel group associated with the point-to-point VIP tunnel.
