Abstract

Network operating methods provide a first packet switch coupled to a second packet switch via a primary packet tunnel having an active status and one or more inactive backup packet tunnels having an inactive status. The methods access data describing at least one performance characteristic of the primary packet tunnel and, based at least on the data, deactivate the primary packet tunnel while still operational and activate one of the backup packet tunnels. Network operating methods provide a first device coupled to a second device via an active primary packet tunnel and one or more inactive backup packet tunnels, access data describing performance characteristics of the one or more backup packet tunnels, and, based at least on the data, deactivate the primary packet tunnel and activate one of the backup packet tunnels.
