RFC 8863
Title: Interactive Connectivity Establishment
Patiently Awaiting Connectivity (ICE PAC)
Author: C. Holmberg,
J. Uberti
Status: Standards Track
Stream: IETF
Date: January 2021
Mailbox: christer.holmberg@ericsson.com,

Pages: 6
Updates: RFC 8445, RFC 8838
I-D Tag: draft-ietf-ice-pac-06.txt
URL: https://www.rfc-editor.org/info/rfc8863
DOI: 10.17487/RFC8863
During the process of establishing peer-to-peer connectivity,
Interactive Connectivity Establishment (ICE) agents can encounter
situations where they have no candidate pairs to check, and, as a
result, conclude that ICE processing has failed. However, because
additional candidate pairs can be discovered during ICE processing,
declaring failure at this point may be premature. This document
discusses when these situations can occur.
This document updates RFCs 8445 and 8838 by requiring that an ICE
agent wait a minimum amount of time before declaring ICE failure,
even if there are no candidate pairs left to check.
This document is a product of the Interactive Connectivity Establishment Working Group of the IETF.
This is now a Proposed Standard.
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 Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
