Abstract: System and method for processing heartbeat messages. A first network device receives heartbeat response messages from two or more of a plurality of network devices. Each heartbeat response message respectively corresponds to one network device of the plurality of network devices. The first network device processes the received heartbeat response messages in kernel space and determines, for each of the plurality of heartbeat response messages, an index value identifying the network device that sent the respective heartbeat response message. The first network device updates heartbeat response message fields in a health check data structure in kernel space based on the generated index values and subsequently processes, in a user space, information received from at least one of the heartbeat response message fields of the health check data structure to obtain health status associated with one or more of the plurality of network devices.

Abstract: In an example of this disclosure, a method may include receiving, by a first network device, a plurality of heartbeat response messages from one or more network devices of a plurality of network devices. Each heartbeat response message of the plurality of heartbeat response messages may respectively correspond to one network device of the plurality of network devices. The method may include processing, by the first network device, the plurality of heartbeat response messages in a kernel space of the first network device. The method may include updating, by the first network device in the kernel space, one or more values corresponding to a data structure based on processing the plurality of heartbeat response messages in the kernel space. The method may include processing, by the first network device, the one or more values in a user space of the first network device.
