Abstract: A system includes multiple (e.g., three) routing elements that receive packets from a gateway and route the packets to multiple core network nodes. In normal operation, the gateway is configured to transmit messages to the first two routing elements with equal priority, while the third routing element is associated with a lower priority and functions as a backup.

Furthermore, the third routing element can be quickly activated to ensure that network service is not significantly impacted while the network is being restored.
