Abstract
Disclosed herein are systems, methods, and computer-readable media for upgrading vSmart controllers. In one aspect, a method includes an edge router receiving a notification from a vSmart controller that an upgrade to the controller will occur. The notification can be dynamically triggered by a centralized network management system. In some embodiments, the vSmart controller can run as a virtual machine (VM) and maintains a control plane connection with one or more edge routers in an overlay network. In response to the notification, a length of time of an expiry timer in which the edge router attempts to connect to the vSmart controller can be increased, and the edge router can connect to the vSmart controller once the increased length of time has passed.
