Title: DECOUPLED CONTROL AND DATA PLANE SYNCHRONIZATION FOR IPSEC GEOGRAPHIC REDUNDANCY
Abstract:
Embodiments disclosed herein relate to systems and methods for separately managing control and data plan contexts for a secure connection during a standby node switchover scenario. Primary and standby nodes for a secure connection can both maintain a data plane context for a secure connection such as IPSec. In the event that the primary node becomes inactive, the standby node can immediately begin processing data plane traffic using the data plane context for the secure connection maintained at the standby node. Control plane information necessary for programming and activating a control plane context can be stored until needed. During a switchover, the standby node can retrieve the control plane information and activate the control plane context after it has begun processing the data plane traffic.
