            Happy Eyeballs Extension for Multiple Interfaces
               draft-ietf-mif-happy-eyeballs-extension-10

Abstract

   This memo proposes extensions to the Happy Eyeball's algorithm
   requirements defined in RFC6555 for use with the multiple
   provisioning domain architecture.  The Happy Eyeballs in MIF would
   make the selection process smoother by using connectivity tests over
   pre-filtered interfaces according to defined policy.  This would
   choose the best interface with an automatic fallback mechanism.
