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.

Abstract: A method provided that is performed at one or more intermediate nodes in a path in a network. The node receives a packet having a header that includes metadata that has been accumulated as the packet travels along the path in the network. The node detects whether a trigger condition has occurred. In response to detecting that the trigger condition has occurred, the node exports, to a destination entity, at least a portion of the metadata that has been accumulated in the header so that the portion of the metadata is removed from the header after it has been exported.
