The IESG has approved the following document: - 'Happy Eyeballs Version 2: Better Connectivity Using Concurrency' (draft-ietf-v6ops-rfc6555bis-07.txt) as Proposed Standard This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Warren Kumari and Benoit Claise. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-v6ops-rfc6555bis/ Technical Summary Many communication protocols operated over the modern Internet use host names. These often resolve to multiple IP addresses, each of which may have different performance and connectivity characteristics. Since specific addresses or address families (IPv4 or IPv6) may be blocked, broken, or sub-optimal on a network, clients that attempt multiple connections in parallel have a higher chance of establishing a connection sooner. This document specifies requirements for algorithms that reduce this user-visible delay and provides an example algorithm. Working Group Summary Strong WG consensus was achieved within six months of document introduction. After WGLC and IETF LC, the authors let the chairs (and me) know that they just realized that there *might* be associated IPR, and wanted to provide as much notice as possible. I held the document while they investigated / discussed with lawyers, and an IPR disclosure has since been filed (https://datatracker.ietf.org/ipr/3077/). Document Quality The current versions of macOS (Sierra) and iOS (10) implement the Happy Eyeballs V2 spec as described.
