A new Request for Comments is now available in online RFC libraries. RFC 6555 Title: Happy Eyeballs: Success with Dual-Stack Hosts Author: D. Wing, A. Yourtchenko Status: Standards Track Stream: IETF Date: April 2012 Mailbox: dwing@cisco.com, ayourtch@cisco.com Pages: 15 Characters: 34048 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-v6ops-happy-eyeballs-07.txt URL: http://www.rfc-editor.org/rfc/rfc6555.txt When a server's IPv4 path and protocol are working, but the server's IPv6 path and protocol are not working, a dual-stack client application experiences significant connection delay compared to an IPv4-only client. This is undesirable because it causes the dual- stack client to have a worse user experience. This document specifies requirements for algorithms that reduce this user-visible delay and provides an algorithm. [STANDARDS-TRACK] This document is a product of the IPv6 Operations Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
