SIP “Torture Tests” for IPv6 now out in RFC 5118

February 12th, 2008 by Dan York

52983DEB-348C-4E43-960B-65166FFCFCE4.jpgIn the list of recently published RFCs, I was intrigued to see RFC 5118, “Session Initiation Protocol (SIP) Torture Test Messages for Internet Protocol Version 6 (IPv6)“. This is really a companion document to RFC 4475 that provides IPv6-related messages you can use while testing SIP. From the overview:

This document is informational, and is *not normative* on any aspect
of SIP.

This document contains test messages based on the current version
(2.0) of the Session Initiation Protocol as defined in [RFC3261].

This document is expected to be used as a companion document to the
more general SIP torture test document [RFC4475], which does not
include specific tests for IPv6 network identifiers.

This document does not attempt to catalog every way to make an
invalid message, nor does it attempt to be comprehensive in exploring
unusual, but valid, messages. Instead, it tries to focus on areas
that may cause interoperability problems in IPv6 deployments.

As IPv6 continues to move (slowly) along, it’s great to see an example like this RFC 5118 that can aid people who are developing SIP apps for IPv6.
