Status of this Memo
This document is an Internet-Draft. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts.
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as ``work in progress.''

The sd session directory tool has been in use for some time on the Mbone for announcing multicast sessions. This document describes an enhanced version of the sd protocol (SDP v2), and explains the extensions to the protocol that have become desirable.
This document is a product of the Multiparty Multimedia Session Control (MMUSIC) working group of the Internet Engineering Task Force. Comments are solicited and should be addressed to the working group's mailing list at firstname.lastname@example.org and/or the authors.
The LBL session directory tool (sd) has been in wide use on the Internet multicast backbone (Mbone) to advertise multimedia conferences and communicate the conference addresses and conference tool-specific information necessary for participation. This document defines an extended version of the session directory protocol and some extensions to the protocol that have become desirable. In the body of the paper, we describe a proposed Session Description Protocol (SDP v2). In Appendix A, we describe how this differs from the protocol currently used by sd (SDP v1). This draft does not describe multicast address allocation or the distribution of SDP messages in detail. These are left to accompanying drafts.
