Title: KEEPALIVE TECHNIQUE IN A NETWORK DEVICE
Abstract:
A network device may execute a process (e.g., a software keepalive process (SKAP)) that enables the network device to continue to send keepalive messages or packets without interruption even during events such as a network operating system failover/switchover for the purpose of high availability or an in-place system upgrade. The network device maintains a database of keepalive network sessions storing information that is used to schedule and send keepalive messages or packets for the keepalive network sessions. The database may be shared between network operating subsystems and programs executed by the network device. The database may be updated by a network operating subsystem and the information may then be used by the SKAP to schedule and send out keepalive messages or packets for the keepalive network sessions. For example, a virtual machine may store information for a keepalive network session in the database, which is used by SKAP to schedule transmission of keepalive packets for that keepalive network session.
