     Network-side Happy Eyeballs based on accurate IPv6 measurement

Abstract

   During the period of IPv6 transition, both ISPs and ICPs (Internet
   Content Providers) care about user's experience in dual-stack
   networks.  They hesitate to provide IPv6 to their users due to the
   fear of poor IPv6 performance.  Network-based Happy Eyeballs (NHE) is
   proposed in this memo as an approach to facilitate ISPs to identify
   IPv6 connectivity issues and provide better connectivity to end
   users.  NHE does accurate measurements and comparison on IPv6/IPv4
   performance on the network side compared with client-side as in Happy
   Eyeballs v2 (HEv2) [RFC8305].  It works independently with client's
   adoption of HEv2 and both coexist without conflicting.

1.  Introduction

   During the period of IPv6 transition, both ISPs and ICPs (Internet
   Content Providers) care about user's experience in dual-stack
   networks.  They hesitate to provide IPv6 to their users due to the
   fear of poor IPv6 performance.  Happy Eyeballs v2 (HEv2) [RFC8305]
   provides an approach to enable clients to attempt multiple
   connections in parallel.  It is helpful to work around the blocked,
   broken, or sub-optimal network.  Taking IPv6 priority consideration
   in design, HEv2 helps increase IPv6 traffic in networks and reduce
   the delay in client side as well if IPv6 connectivity is poorer.  So
   far, most modern web browsers support HEv2 very well, thanks to
   popular web browser engines, such as WebKit and Trident.  However, in
   practice there are still some barriers keeping Mobile developers who
   develop Apps with APIs and libs which don't not implementing HEv2.
