Stack Management for MPLS Network Actions: Integration of Nodes with Limited Hardware Capabilities
The MPLS Network Actions (MNA) framework enhances MPLS forwarding with a generalized encoding for manifold extensions such as network slicing and in-situ OAM (IOAM). Network actions in MNA are encoded in Label Stack Entries (LSEs) and are added to the MPLS stack. Routers have a physical limit on the number of LSEs they can read, called the readable label depth (RLD). With MNA, routers must be able to process a minimum number of LSEs which requires a relatively large RLD. In this paper, we perfo…
