Synchronous Optical Network/Synchronous Digital Hierarchy Circuit Emulation Service over MPLS Encapsulation
RFC 5143, “Synchronous Optical Network/Synchronous Digital Hierarchy Circuit Emulation Service over MPLS Encapsulation”, is a Historic document published in February 2008 by A. Malis, J. Brayley, J. Shirron, L. Martini, S. Vogelsang. It has been obsoleted by RFC 4842 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a historical method for encapsulating Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Path signals for transport across packet-switched networks (PSNs). The PSNs explicitly supported by this document include MPLS and IP. Note that RFC 4842 describes the standards-track protocol for this functionality, and new implementations must use RFC 4842 rather than this document except when interoperability with older implementations is desired. This memo defines a Historic Document for the Internet community.
What “Historic” means
