Abstract

When a server's IPv4 path and protocol are working, but the server'sIPv6 path and protocol are not working, a dual-stack clientapplication experiences significant connection delay compared to anIPv4-only client. This is undesirable because it causes the dual-stack client to have a worse user experience. This documentspecifies requirements for algorithms that reduce this user-visibledelay and provides an algorithm. [STANDARDS-TRACK]
