A new Request for Comments is now available in online RFC libraries. RFC 3308 Title: Layer Two Tunneling Protocol (L2TP) Differentiated Services Extension Author(s): P. Calhoun, W. Luo, D. McPherson, K. Peirce Status: Standards Track Date: November 2002 Mailbox: pcalhoun@bstormnetworks.com, luo@cisco.com, danny@tcb.net, Ken@malibunetworks.com Pages: 10 Characters: 21536 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-l2tpext-ds-05.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3308.txt This document describes mechanisms which enable the Layer Two Tunneling Protocol (L2TP) to negotiate desired Per Hop Behavior (PHB) code for the L2TP control connection, as well as individual sessions within an L2TP tunnel. L2TP provides a standard method for tunneling PPP packets. The current specification provides no provisions for supporting Differentiated Services (diffserv) over the L2TP control connection or subsequent data sessions. As a result, no standard mechanism currently exists within L2TP to provide L2TP protocol negotiations for service discrimination. This document is a product of the Layer Two Tunneling Protocol Extensions Working Group of the IETF. This is now a Proposed Standard Protocol. This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
