	Title           : Media Description for IKE in the Session Description Protocol (SDP)
	Author(s)       : M. Saito, et al.
	Filename        : draft-saito-mmusic-sdp-ike-06.txt

This document specifies how to establish secure media sessions over a
virtual private network using Session Initiation Protocol for the
purpose of on-demand media/application sharing between peers.  It
extends the protocol identifier of Session Description Protocol (SDP)
so that it can negotiate the use of Internet Key Exchange Protocol
(IKE) for media sessions in the SDP offer/answer model.  It also
specifies the method to boot up IKE and generate IPsec security
associations using a self-signed certificate under the mechanism of
connection-oriented media transport over the Transport Layer Security
in the SDP (comedia-tls).  This document extends RFC 4572.  In
addition, it defines a new attribute "udp-setup", which is similar to
the "setup" attribute defined in RFC 4145, to enable endpoints to
negotiate their roles in an IKE session.  To use pre-shared keys for
authentication in IKE, a new attribute "psk-fingerprint" is also
defined.Conventions used in this document

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
