Abstract: Presented herein are techniques that enable fast switchover or reversion between label switched paths. In accordance with examples presented herein, a working label switched path is added 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. A restoration label switched path associated with the working label switched path is also added to the fast switchover protection group. The fast switchover protection group is stored at the ingress network device. After storing the fast switchover protection group at the ingress network device, at least the working label switched path is used to carry traffic through the transport network.

Abstract: A method is disclosed for use by a network element coupled with an optical transport network. The method comprises calculating an optical path from a first packet-terminated optical interface of the network element to a second packet-terminated optical interface of a destination network element coupled with the optical transport network, and signaling the optical transport network to create the optical path. The method further comprises creating an Ethernet interface corresponding to the first packet-terminated optical interface, and adding the Ethernet interface to an Ethernet bundle interface. The method further comprises communicating across the optical path using addressing of the Ethernet bundle interface.
