Protection of routers in a telecommunications network
A set of router table entries is used to form a set of p-cycles in an Internet provider network, which have no capacity unless they are required to carry packet traffic. If a packet is intended to travel over a route between nodes (12-14) and a node (10) has failed, the source router (12) detours th...

| Zusammenfassung: | A set of router table entries is used to form a set of p-cycles in an Internet provider network, which have no capacity unless they are required to carry packet traffic. If a packet is intended to travel over a route between nodes (12-14) and a node (10) has failed, the source router (12) detours the packet onto a p-cycle after encapsulating it in a p-cycle packet. Routers then pass the packet to its destination node. An independent claim is included for a telecommunication network and for a data packet. |
