Abstract
Virtual cable modem termination system redundancy may be provided. First, a new virtual cable modem termination system (vCMTS) instance may be spawned. Then a backhaul connection between the new vCMTS instance and a data center network may be created. Next, a database connection between the new vCMTS instance and a database may be created. Upstream and downstream traffic of a node may then be switched from an active vCMTS instance to the new vCMTS instance.
