Currently each unit has a single (possibly dual connected) primary campus network connection with annexe connections to their other locations across campus. However should for any reason their primary location become unavailable (e.g. loss of power), then all their annexe locations immediately suffer a loss of campus connectivity as this is routed through their now unavailable primary location. Ettin addresses this resiliency concern by introducing automatic backup connectivity via one of their other locations. Ettin uses the powerful and very well established Border Gateway Protocol (BGP) to automatically manage the consistent selection of a unit’s primary and backup route to and from campus. In the event of primary connectivity failure (e.g. through loss of power), the routing automatically switches over to a backup route (probably via another building) until the primary route becomes available again, when connectivity automatically switches back.
