Description of Working Group:

The MBONE Deployment Working Group will be a forum for coordinating the deployment, engineering, and operation of multicast routing protocols and procedures in the global Internet. This activity will include, but not be limited to:

- Deployment of multicast routing in the global Internet.

- Receive regular reports on the current state of the deployment of mbone technology. Create "practice and experience" documents that capture the experience of those who have deployed and are deploying various MBONE technologies (e.g. PIM, DVMRP, CBT).

- Based on reports and other information, provide feedback to IDMR.

- Develop mechanisms and procedures to aid in the transition to native multicast, where appropriate.

- Develop mechanisms and procedures for sharing operational information to aid in operation of the global MBONE.

- Development of guidelines to improve the use of administratively scoped multicast addresses.

- Develop mechanisms and procedures for creating and maintaining a MBONE topology database.

This working group will initially interact closely with IDMR. It is believed that, once hierarchical multicast routing systems are specified and deployed, the working groups will diverge somewhat. Finally, note that in the below 'Goals & Milestones', the type of RFC will be subject to discussions within the working group.

Goals and Milestones:

Sep 96


Submit Internet-Draft on inter-provider coordination of the deployment of pruning mrouteds.

Sep 96


Establish initial charter, goals, and long-term group agenda.

Jan 97


Submit Internet-Draft outlining requirements for the existing MBONE infrastructure.

Apr 97


Submit Internet-Draft specifying the use of administratively scoped multicast addresses.

Jun 97


Begin work, with RPS WG, on extensions to RPSL to describe multicast routing policy.

Jun 97


Submit Internet-Draft specifying the use of aggregation for DVMRP (and, in general where applicable). In addition, address the use of DVMRP default.

Sep 97


Submit Internet-Draft specifying the use of native multicast where appropriate (e.g. exchange points).

Sep 97


Begin work on document of co-existence strategies for IPv4 multicast and IPv6 multicast.

Dec 97


Begin work on a document describing the deployment of inter-provider hierarchical multicast routing coordination (or, when available).

Current Meeting Report

Minutes of the MBONE Deployment (mboned) WG

The group decided that the admin-scope draft should go forward as an MBONED document.

Mark Handely introduced the Multicast Scope Zone Announcement protocol, which is designed to solve the following three problems: Scope Discover, Scope Leaks (through misconfiguration), and Nonconvex Scopes (again, misconfiguration).

Kurt Windish (UO) and Rusty Eddy provided PIM implementation updates.

Meyer talked about a new Internet multicast architectures. Will write a document for MBONED
describing this.

Dino Farinacci talked about a DNS Based RP Placement scheme. The problem is that the current architecture (described above by Meyer) requires co-location of RPs on a common interconnect.

Bill Fenner talked about multicast route stability. Results on http://ganef.cs.ucla.edu/~masseyd/Route

Ross Finlayson talked about UDP Multicast Tunneling. This is an approach to solving the problem that many PCs can't do multicast or tunneling. The idea is to provide a minimal changes solution that can be used for tunneling on PCs. This solution uses udp-in-udp tunneling (user pc at one end, server at the other).

Kevin Almeroth talked about the Interactive Mmedia Jukebox (IMJ), and about MBONE "viewership" studies. He reported on the alarming trend that fewer people are using the MBONE than in the past.

Youngguang Zhang talked about a Hughes pilot for sending MBONE over Satellite. The project was used during MBONE traffic during this IETF. Uses the directPC system to carry IP Mulitcast. He mentioned three major issues:
