RFC 6290 · PROPOSED STANDARD · 2011

A Quick Crash Detection Method for the Internet Key Exchange Protocol

Overview

RFC 6290, “A Quick Crash Detection Method for the Internet Key Exchange Protocol”, is a Proposed Standard document published in June 2011 by Y. Nir, D. Wierbowski, F. Detienne, P. Sethi. The canonical text is published by the RFC Editor.

Abstract

This document describes an extension to the Internet Key Exchange Protocol version 2 (IKEv2) that allows for faster detection of Security Association (SA) desynchronization using a saved token.

When an IPsec tunnel between two IKEv2 peers is disconnected due to a restart of one peer, it can take as much as several minutes for the other peer to discover that the reboot has occurred, thus delaying recovery. In this text, we propose an extension to the protocol that allows for recovery immediately following the restart. [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
