MPLS-LSP Data Plane for Cyclic Queuing and Forwarding

Large-scale Deterministic Network (LDN) [ldn] aims to achieve bounded latency forwarding on layer-3 networks that contain long-distance links, large number of nodes and flows. LDN requires a data plane mechanism to indicate different forwarding cycles in the upstream node. This document proposes to use multiple MPLS labels to indicate this kind of information, for MPLS-LSP data plane.
