Ballot Text

Technical Summary 

   When the IPv4 server and path is working but the IPv6 server or IPv6
   path is down, a dual-stack client application experiences significant
   connection delay compared to an IPv4-only client.  This is
   undesirable because it causes the dual-stack client to have a worse
   user experience.  This document specifies requirements for algorithms
   that reduce this delay, and provides an example algorithm.
Working Group Summary 

    v6ops considered this carefully, and tested various possible implementations of the solution.

Document Quality 

   The document appears to be of high quality per the numerous reviews received.
