Encapsulation of Simple Two-Way Active Measurement Protocol for LSPs and Pseudowires in MPLS Networks

This document describes the procedure for encapsulation of the Simple Two-Way Active Measurement Protocol (STAMP) defined in RFC 8762 and its optional extensions defined in RFC 8972 in MPLS networks. Label Switched Paths (LSPs) and Pseudowires (PWs) are used in MPLS networks for various services including carrying Layer 2 and Layer 3 data packets and may optionally carry Control Word (CW). The procedure is also described to encapsulate the STAMP test packets with or without using an IP/UDP header for the LSPs and PWs that carry CW.
