Abstract
Many communication protocols operating over the modern Internet usehostnames. These often resolve to multiple IP addresses, each ofwhich may have different performance and connectivitycharacteristics. Since specific addresses or address families (IPv4or IPv6) may be blocked, broken, or sub-optimal on a network, clientsthat attempt multiple connections in parallel have a chance ofestablishing a connection more quickly. This document specifiesrequirements for algorithms that reduce this user-visible delay andprovides an example algorithm, referred to as "Happy Eyeballs". Thisdocument obsoletes the original algorithm description in RFC 6555.
