REMINDER: The RSSAC wishes to investigate best practices to optimize the distribution of root server instances in order to maximize root service resiliency, and to reduce the Round-Trip Time (RTT) between recursive servers and root servers.  It requests Kaveh Ranjbar to lead a Caucus work party to produce a report, with adherence to RSSAC Caucus procedures.

 

The work party is asked to consider a number of issues related to the distribution of anycast instances of the root name service, including:

 

• Given the state of current internet technology, what is the maximum latency a relying party should experience when transacting with the DNS root service as opposed to with a single “root server?”
• Will adding more instances in more topologically diverse locations make the system more resilient to Denial Of Service (DOS) attacks?
• If root operators were to coordinate their deployments of anycast instances, what considerations should be contemplated?
• Are there any regional or global technological risks (or benefits) if only a subset of operators (versus all or the majority of root operators) deploy anycast instances?

 

 

 REMINDER:  If you are interested in this topic and would like to join this work party, please email Kathy Schnitt kathy.schnitt@icann.org by close of business 19 October 2016.  A list of interested parties I have so far are Marc Blanchet, Ondrej Sury, Suresh Krishnaswamy, Shane Kerr, Abby Pan and Ray Bellis.
