Please distribute to your colleagues and consider applications / nominations of candidates with suitable contributions! Best regards, Thomas -------- Original Message -------- Subject: [IRTF-Announce] FIVE DAYS REMAINING: Call for Nominations: Applied Networking Research Prize (ANRP) Date: Tue, 3 May 2011 15:27:39 +0300 From: Lars Eggert Reply-To: anrp@isoc.org To: irtf-announce@irtf.org CALL FOR NOMINATIONS: APPLIED NETWORKING RESEARCH PRIZE (ANRP) *** Apply until May 8, 2011 for the ANR Prize for IETF-81, *** July 24-29, 2011 in Quebec City, Canada! The Applied Networking Research Prize (ANRP) is awarded for recent results in applied networking research that are relevant for transitioning into shipping Internet products and related standardization efforts. Researchers with relevant, recently published results are encouraged to apply for this prize, which will offer them the opportunity to present and discuss their work with the engineers, network operators, policy makers and scientists that participate in the Internet Engineering Task Force (IETF) and its research arm, the Internet Research Task Force (IRTF). Third-party nominations for this prize are also encouraged. The goal of the Applied Networking Research Prize (ANRP) is to recognize the best new ideas in networking, and bring them to the IETF and IRTF especially in cases where they would not otherwise see much exposure or discussion. The Applied Networking Research Prize (ANRP) consists of: * cash prize of $500 (USD) * invited talk at the IRTF Open Meeting * travel grant to attend the week-long IETF meeting (airfare, hotel, registration, stipend) * recognition at the IETF plenary * invitation to related social activities * potential for additional travel grants to future IETF meetings, based on community feedback The Applied Networking Research Prize (ANRP) will be awarded three times per year, in conjunction with the three annual IETF meetings. HOW TO APPLY Applicants must nominate a peer-reviewed, recently-published, original journal, conference or workshop paper. Both self nominations (nominating one's own paper) and third-party nominations (nominating someone else's paper) are encouraged. The nominee must be one of the main authors of the nominated paper. The nominated paper should provide a scientific foundation for possible future IETF engineering work or IRTF experimentation, analyze the behavior of Internet protocols in operational deployments or realistic testbeds, make an important contribution to the understanding of Internet scalability, performance, reliability, security or capability, or otherwise be of relevance to ongoing or future IETF or IRTF activities. Applicants must briefly describe how the nominated paper relates to these goals, and are encouraged to describe how presentation of these research results will foster their transition into new IETF engineering or IRTF experimentation, or otherwise seed new activities that will have an impact on the real-world Internet. The goal of the Applied Networking Research Prize (ANRP) is to foster the transitioning of research results into real-world benefits for the Internet. Therefore, applicants must indicate that they (or the nominee, in case of third-party applications) are available to attend the respective IETF meeting in person and in its entirety. Applications must include: * the name and email address of the nominee * a reference to the published nominated paper * a PDF copy of the nominated paper * a statement that describes how the nominated paper fulfills the goals of the award * a statement that the nominee is available to attend the respective IETF meeting in person and in its entirety * a brief biography or CV of the nominee * optionally, any other supporting information (link to nominee's web site, etc.) *** Applications are submitted by email to anrp@isoc.org. *** SELECTION PROCESS A small selection committee comprised of individuals knowledgeable about the IRTF, IETF and the broader networking research community will evaluate the submissions against these selection criteria. The goal is to select 1-2 submissions for the Applied Networking Research Prize (ANRP) during each application period. All applicants will be notified by email. IMPORTANT DATES Applications open: April 11, 2011 Applications close: May 8, 2011 Notifications: May 31, 2011 IETF-81 Meeting: July 24-29, 2011 SPONSORS The Applied Networking Research Prize (ANRP) is supported by the Internet Society (ISOC), as part of its Internet Research Award Programme, in coordination with the Internet Research Task Force (IRTF).

This works fine for IPv6/MLD by looking into the /proc/net/SNMP6 table. For IPv4/IGMP, the SNMP approach does not work. I can detect an IGMPv2 querier by monitoring 'Timer' in the /proc/net/igmp table: this counts down the [Unsolicited Report Interval]. However, this does not exist for IGMPv3, as reports are not suppressed. My question is about IGMPv3. Does anybody know how to detect the presence of an IGMPv3 querier based on the kernel states of a multicast client?

I see e.g.: Idx Device : Count Querier Group Users Timer Reporter 1 lo : 0 V3 010000E0 1 0:00000000 0 2 eth0 : 3 V3 010000E0 1 0:00000000 0 Doesn't this work?
