Abstract: In one embodiment, a Segment Routing network node provides efficiencies in processing and communicating Internet Protocol packets in a network. An Internet Protocol (IP) packet, possibly a Segment Routing packet, is received by a node in a network, which updates the packet according to a corresponding Segment Routing Policy, that includes an ordered list of Segment Identifiers comprising, in first-to-last order, a first Segment Identifier followed by one or more subsequent Segment Identifiers. The updating of the packet includes setting the Destination Address to the first Segment Identifier, and adding said one or more subsequent Segment Identifiers, but not the first Segment Identifier, in a first Segment Routing Header. The updated packet is sent into the network without the first Segment Identifier being added to a Segment Routing Header in response to the Segment Routing Policy.
