A method for obtaining, by a first network device of a pair of network devices, a packet, wherein the packet specifies a source address corresponding to a first client device and a destination address corresponding to a second client device, making a first determination, by the first network device and using the source address and the destination address, that the first network device is not an owner of bidirectional traffic associated with the packet, based on the first determination, transmitting, by the first network device, the packet to a second network device of the pair of network devices, making a second determination, by the second network device, that the second network device is the owner of bidirectional traffic associated with the packet, performing, in response to the second determination and by the second network device, data processing on the packet to generate a processing result.

Mechanism to manage bidirectional traffic for high availability network devices

Keepalive packets are transmitted between a sender node and a receiver node at an interval that varies depending on the transit times of previously transmitted keepalive packets. The transit time is based on when a keepalive packet is transmitted to the receiver node and when a corresponding feedback packet is received from the receiver node. The transmission interval varies depending on the path conditions between the sender node and the receiver node, which may be reflected in the transit time.

Adjustable keepalive timer

Systems and methods for load balancing in a network are disclosed. An illustrative method includes receiving network telemetry data corresponding to network paths of a plurality of coexisting multipaths, performing an adaptive load balancing process by determining whether a network path from the plurality of coexisting multipaths is an adequate network path based on the network telemetry data, and in response to determining the network path is an adequate network path, selecting the network path for a network flow.
