Abstract: A method, apparatus, and computer readable medium are disclosed. In one embodiment of the method, a packet and a segment ID stack is received at a first segment routing enabled node. The segment ID stack includes a plurality of segment IDs, one or which is a first area-segment ID that identifies a first area of a subdivided segment routing network. An egress interface of the first segment routing enabled node is selected based on the first area-segment ID. Thereafter, the packet is forwarded via the selected egress interface.

Abstract: In one embodiment, a packet and a segment ID stack is received at a node. The segment ID stack includes a plurality of segment IDs, one or which is a first area-segment ID that identifies a first area of a subdivided network. One of a plurality of forwarding tables at the node is selected based on the first area-segment ID. Thereafter, the packet is forwarded based on information contained in the selected forwarding table.

Abstract: A method for augmenting metadata of a network service header is disclosed. The method includes receiving, at a first service node, a packet or frame of a traffic flow, wherein the packet has a payload and the network service header including a first metadata and a first service path information for the traffic flow, classifying, by the first service node, at least one of the payload and the first metadata to generate a second metadata different from the first metadata, and augmenting, by the first service node, the first metadata using the second metadata before forwarding the packet or frame to a second service node.
