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.
