Subject: Operator survey for multicast deployments


In the IETF pim WG, we're trying to advance the PIM-SM spec (RFC 4601)
on the IETF standards track, and we need to see what features are
deployed and used etc. We are sending out a questionnaire to operators
to NANOG and RIPE etc. but it would be good to get responses from NRNs
that all are deploying PIM-SM too.

Is there a suitable TERENA list I can send it to? I guess in the old
days tf-ngn would work, not sure which is best now?

Below is the questionnaire we want to send. I'm happy sending it myself,
but including it here for you to see what it is about.

Stig


Questionnaire for Operators:

Introduction:

PIM-SM was first published as RFC 2117 in 1997 and then again as
RFC 2362 in 1998.  The protocol was classified as Experimental in
both of these documents.  The PIM-SM protocol specification was
then rewritten in whole and advanced to Proposed Standard as
RFC 4601 in 2006. Considering the multiple independent
implementations developed and the successful operational
experience gained, the IETF has decided to advance the PIM-SM
routing protocol to Draft Standard.  This survey intends to
provide supporting documentation to advance the Protocol
Independent Multicast - Sparse Mode (PIM-SM) routing protocol
from IETF Proposed Standard to Draft Standard. (Due to RFC 6410,
now the intention is to progress it to Internet Standard.  Draft Standard
is not used anymore.)

This survey is issued on behalf of the IETF PIM Working Group.

The responses will be collected by neutral third-party and kept
strictly confidential; only the final combined results will be
published.  Marshall Eubanks has agreed to anonymize the response
to this Questionnaire.  Marshall has a long experience with
Multicast but has no direct financial interest in this matter,
nor ties to any of the vendors involved.  He is also a member of
the IAOC, Chair of the IETF Trust and co-chair of the IETF
Layer 3 VPN Working Group.  Please send Questionnaire responses
to his email address, 
.
  He requests
that such responses include the string
  "RFC 4601 bis Questionnaire"
in the subject field.

Before answer the questions, please fill the following background
information.

Questions:

1       Have you deployed PIM-SM in your network?

2       How long have you had PIM-SM deployed in your network?
       Do you know if your deployment is based on the most recent
       RFC4601?

3       Have you deployed PIM-SM for IPv6 in your network?

4       Are you using equipment with different (multi-vendor) PIM-SM
       implementations for your deployment?

5       Have you encountered any inter-operability or backward-
       compatibility issues amongst differing implementations?
       If yes, what are your concerns about these issues?

6       Have you deployed both dense mode and sparse mode in your
       network?

       If yes, do you route between these modes using features such
       as *,*,RP or PMBR?

7       To what extent have you deployed PIM functionality, like BSR,
       SSM, and Explicit Tracking?

8       Which RP mapping mechanism do you use: Static, AutoRP, or BSR?

9       How many RPs have you deployed in your network?

10      If you use Anycast-RP, is it Anycast-RP using MSDP (RFC 3446)
       or Anycast-RP using PIM (RFC 4610)?

11      Do you have any other comments on PIM-SM deployment in your
       network?
