Claim Text:
1. A computer-implemented method comprising: adding, using a processor, a working label switched path to a fast switchover protection group that is configured to carry traffic from an ingress network device to an egress network device through a transport network; adding, using the processor, a protecting label switched path to the fast switchover protection group, wherein the protecting label switched path is associated with the working label switched path to be a backup path for the working label switched path; adding, using the processor, a first restoration label switched path to the fast switchover protection group, wherein the first restoration label switched path is associated with the working label switched path to provide failure support for the working label switched path; adding, using the processor, a second restoration label switched path to the fast switchover protection group, wherein the second restoration label switched path is associated with the protecting label switched path to provide failure support for the protecting label switched path; storing, using the processor, the fast switchover protection group that includes the working label switched path, the protecting label switched path, the first restoration label switched path and the second restoration label switched path at the ingress network device; and after storing the fast switchover protection group at the ingress network device, using at least the working label switched path to carry traffic through the transport network.
