A new Request for Comments is now available in online RFC libraries. RFC 5143 Title: Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Circuit Emulation Service over MPLS (CEM) Encapsulation Author: A. Malis, J. Brayley, J. Shirron, L. Martini, S. Vogelsang Status: Historic Date: February 2008 Mailbox: andrew.g.malis@verizon.com, jeremy.brayley@ecitele.com, john.shirron@ecitele.com, lmartini@cisco.com, steve.vogelsang@alcatel-lucent.com Pages: 24 Characters: 52534 Obsoleted by: RFC4842 I-D Tag: draft-malis-sonet-ces-mpls-09.txt URL: http://www.rfc-editor.org/rfc/rfc5143.txt 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.
