Diameter Interop Report (1)  Date: Jan 29 - Feb 1, 2007 (Orlando)  Host: Intellinet Technologies  Participants: 14 companies  Report: eterInterop eterInterop2007  Test Cases: interop-test-suite-04.txt  A summary of issues raised by the participants can be found in:

Diameter Interop Report (2)  Only a few new bugs found in RFC  Diameter with SCTP support works fine and a number of companies implement SCTP support (7 out of 14 at this interop event).  TLS over TCP support is available but RFC 3588 lacks more details about the security checks that have to be performed. Certificate configuration turns out to be difficult and time consuming.  TLS over SCTP support was only implemented (as a prototype) by a single company.  Election tests are very difficult to perform due to the timing problems.  Dynamic peer discovery is rarely implemented and people don’t see deployment need for them.  A few Diameter EAP and Diameter NASREQ implementations are available.  We do not see a lot of Diameter Mobile IP (only 2) and the Diameter SIP application (zero!) implementations at the interop.  Significant interest in testing Diameter Credit Control.

Diameter QoS  Involving a group of experienced people to get some feedback:  Elwyn Davies (IAB member, background in IETF QoS work)  Martin Stiemerling (NSIS working group chair)  Jouni Korhonen (3GPP background)  Michael Montemurro (IEEE background)  Avi Lior (Wimax, 3GPP2 background)  Potentially going to schedule phone conferences and Jabber chats
