The IESG has approved the following document: - 'QoS Signaling in a Nested Virtual Private Network ' <draft-ietf-tsvwg-vpn-signaled-preemption-02.txt> as an Informational RFC This document is the product of the Transport Area Working Group Working Group. The IESG contact persons are Magnus Westerlund and Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-tsvwg-vpn-signaled-preemption-02.txt Technical Summary More and more networks wish to guarantee secure transmission of IP traffic for across public LANs or WANs and therefore use Virtual Private Networks. Some networks require communication between an interior and exterior portion of a VPN, but have sensitivities about what information is communicated across the boundary. This document seeks to outline the issues and the nature of the proposed solutions. The outline of the QoS solution for real-time traffic has been described at a high level in RFC 4542. The thrust of this document involves VPNs that use encryption in some form, such as IPsec. As a result, this document will discuss the VPN Router supporting "plaintext" and "ciphertext" interfaces. However, the concept extends readily to any form of aggregation, including the concept proposed in [RFC3175] of the IP traffic entering and leaving a network at identified points, and the use of other kinds of tunnels including GRE, IP/IP, MPLS, and so on. Working Group Summary There is strong consensus in the WG to publish this document. It has been reviewed by several people prior to and in the WG last call. Comments raised have been addressed. Protocol Quality This document does not propose any protocol extension. This document has been well reviewed in the WG and comments raised have been addressed. Magnus Westerlund was the responsible AD. James Polk was WG shepherd. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
