routing resiliency survey
by Andrei Robachevsky 02 Oct '12

02 Oct '12

Colleagues, Last week at the Routing WG I made a short presentation about our effort to facilitate collection of some operational data related to routing resiliency. We are looking for some statistics and analysis from the NOC side. I understand there might be concerns regarding the disclosure of such information, but we hope we can figure out how to handle sensitivities, on a case by case basis. To give you a better idea of what I am talking about (and was talking about at RIPE65) I attach the survey itself. Please contact me if you are interested in taking part in this survey. I also appreciate any concrete suggestions regarding the questions or the survey in general. Regards, Andrei -- Andrei Robachevsky Technology Program Manager Internet Society www.isoc.org

PIM survey for operators (round 2)
by Stig Venaas 25 Sep '12

25 Sep '12

The IETF pim working group is conducting a survey in order to advance the PIM Sparse Mode spec on the IETF Standards Track, and would like input from operators. The survey ends October 24th. Please note that we did this survey previously with a deadline in July. But owing to unforeseen circumstances we need to restart this survey. We are acutely aware that this is an additional burden on the people who took the time to respond before. We hope that they will re-send their responses - maybe they are still filed in their sent emails. Please see below for more information. thank you, pim chairs Mike & Stig ---- 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 no longer used.) This survey is issued on behalf of the IETF PIM Working Group. The responses will be collected by a neutral third-party and kept strictly confidential; only the final combined results will be published. Tim Chown and Bill Atwood have agreed to anonymize the response to this Questionnaire. They have a long experience with multicast but have no direct financial interest in this matter, nor ties to any of the vendors involved. Tim is working at University of Southampton, UK, and he has been active in the IETF for many years, including the mboned working group, and he is a co-chair of the 6renum working group. Bill is at Concordia University, Montreal, Canada, and he has been an active participant in the IETF pim working group for over ten years, especially in the area of security. Please send questionnaire responses addressed to them both. The addresses are tjc(a)ecs.soton.ac.uk and william.atwood(a)concordia.ca. Please include the string "RFC 4601 bis Questionnaire" in the subject field. Before answering the questions, please complete the following background information. Name of the Respondent: Affiliation/Organization: Contact Email: Provide description of PIM deployment: Do you wish to keep the information provided confidential: 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?
