Patent Images
1. A method comprising:
- a node receiving a packet with an attached segment ID stack, wherein the segment ID stack comprises a first segment ID, a second segment ID, and a service segment ID, wherein the first segment ID and the service segment ID correspond to the node and a service provided by the node, respectively, wherein the second segment ID corresponds to another node, and wherein the node and the other node are in a network of nodes;
the node processing the packet in accordance with the service;
the node forwarding the packet after it is processed.

Abstract
An apparatus and method is disclosed for segment routing (SR) over label distribution protocol (LDP). In one embodiment, the method includes a node receiving a packet with an attached segment ID. In response, the node may attach a label to the packet. Thereafter, the node may forward the packet with the attached label and segment ID to another node via a label switched path (LSP).
