Abstract:
In one embodiment, segment routing network processing of packets is performed, including using segment routing packet policies and functions providing segment routing processing signaling and packet forwarding efficiencies in a network. A segment routing node signals to another segment routing node using a signaled segment identifier in a segment list of a segment routing packet with the segments left identifying a segment list element above the signaled segment identifier. A downstream segment routing node receives the segment routing packet, obtains this signaled segment identifier, and performs processing of one or more packets based thereon. In one embodiment, a provider edge node replaces its own segment identifier in a received customer packet, with a downstream customer node using the replaced (signaling) segment identifier (of a provider edge node/segment routing function) for accessing a return path through the provider network.

Claim (Index 19):
An apparatus, comprising:\n one or more hardware interfaces sending and receiving packets in a network; and one or more network processors with memory associated therewith; wherein the apparatus, communicatively coupled to a network, performs packet processing operations including segment routing-capable (SR-capable) packet processing operations, with a particular segment identifier being an Internet Protocol address of the apparatus, and with said packet processing operations including: receiving from the network a particular segment routing packet including a particular segment routing header comprising a particular segment list and a particular segments left, with the particular segment list when said received by the apparatus comprising the particular segment identifier in the last segment list element and a second segment identifier, with the segments left when said received identifying the last segment list element; and sending into the network the particular segment routing packet as updated by the apparatus, with said updates to the particular segment routing packet including replacing the particular segment identifier with a signaled segment identifier in the particular segment list and modifying the segments left to identify the second segment identifier in the particular segment list.
