4 Interoperability Testing
4.1 Purpose/ Objectives

The purpose of interoperability testing is to verify the TIPHON specifications and interoperability of different

implementations. These tests can either take place in a single room, “classic" or “face-to-face" Interoperability Events,

or can be spread over the whole world using remote connectivity, then they are called remote Interop events.

4.2 Testing

Testing will verify all TIPHON scenarios (that is, PC to PC, PC to Phone, Phone to PC, and Phone to Phone). Testing

will attempt to completely demonstrate and debug these services, rather than just concentrate on the specific protocol

elements that are required.
4.3 Privacy

The result of the tests will not be in any case available outside TIPHON membership, nor may it be used in any case

under any situation to promote some products as being "more" TIPHON compliant than others, or for any other purpose

other than the verification and debugging of the TIPHON specifications.

There will be no formal kind of NDA to be filled out, but there is always a kind of gentleman’s agreement not to

disclose any individual results.

Documents that request changes to the TIPHON specifications as a result of the Interoperability events will not directly

reference the vendor that found the fault.
4.4 Responsible WG

Interoperability events will be operated under the responsibility of WG6, with support from the relevant protocol

generating and specifying WGs (i.e. WG3, WG4, and WG5).
4.5 Test Procedures
Test specifications of all TIPHON scenarios can be found in TS 101 335 [1].
4.6 Test Scoring
In tests which are scored, score sheets are distributed based on TS 101 335 [1].
4.7 Participation
4.7.1 Joint events
TIPHON interoperability events are in general organized jointly with IMTC CoIP.
4.7.2 Who can participate

Participation is open to ETSI members, ETSI associate members, IMTC members, and companies in the application

process to become a member of ETSI or IMTC. Participants need to have products or services available for testing with

other companies. Companies simply wanting to observe the testing will not be allowed to attend the event.

5 Interoperability Events

Interoperability events can take place as face-to-face events, or as remote events.

5.1 Face-to-face Interoperability Events

The classical way to test interoperability is to meet in a room and connect multiple systems together.

5.1.1 Organization

Interoperability events are in general organized together with the CoIP (Conferencing over IP) Activity Group of IMTC

(International Multimedia Teleconferencing Consortium).

Annex 1, "Guidelines for the organization of interoperability events", summarizes the experience gained from multiple

interoperability events and may prove useful for future organizers of Interoperability events.

5.1.2 Registration

Prior to any Interop the participants have to register. To optimize this process and to easily provide detailed information

to the other participants ETSI has installed the VIMP. More details are described in clause 7 of the present document.

5.1.3 Scheduling

Scheduling is one of the most difficult aspects of Interop Events. As a consensus we can state that the participants prefer

65% of the time as ad hoc, self scheduled tests and 35% of the time as scheduled by the organizers.

Scheduled tests in face-to-face interoperability events are intended to test the interoperability of a large number of

participants in a minimum of time. Thus the timeslots are pretty short and there is no time for the companies to debug.

Extensive analyses and debugging can take place in the ad-hoc test time after the scheduled tests.

5.1.4 Frequency

Here is some feedback collected at two post Interoperability Events in Boston and Sophia Antipolis.

How many Interop Event should there be per year?
4-99 Boston 6-99 Sophia Antipolis
1 per year 0% 2 %
2 per year 18 % 18 %
3 per year 30 % 45 %
4 per year 49 % 30 %
6 per year 3 % 5 %
Average 3,4 3,2

5.2 Remote Interoperability Events

Remote Interoperability Events provide companies the opportunity to test interoperability in their own labs without

buying other companies equipment. They can interconnect to other parties via the public Internet or the ETSI ISDN

router.
5.2.1 Organization

The organization of a remote interoperability event is different from a face to face event. There is no need to arrange a

room and prepare accommodation, but in order to organize an effective event the information for the participants have to

be much more detailed and precise, as communication is much more complicated and solving simple problems may be

very time-consuming.
5.2.2 Registration

Prior to any Interop the participants have to register. To optimize this process and to provide detailed information to the

other participants in any effective way, ETSI has installed the VIMP. More details are described in clause 7 of the

present document.

The information provided about other participants equipment is very important for remote interoperability events, as it is

much more complicated to collect details at a later stage.
These details include:

- Time of day the contact person is present in the company and able to do testing;

- Ability to test using the pubic internet;
- Ability to test using the TIPHON Interop Router;
- IP-Address of device ( if known and important for test);
- Alias the Endpoint is going to register with;
- Gateway Prefix, the Gateway is going to register with, or Endpoint Alias;
- Number an Endpoint has to dial to reach a telephone connected to the Gateway.
5.2.3 Communication

The communication is simple if you are sitting together in one room. If you test remotely, you must have a telephone

conference or a simple chat tool to communicate the progress of the test. A chat tool also allowS the co-ordinator to be

informed about the progress of a test.
5.2.4 Time

As TIPHON is a world-wide project we have different time zones for the participating companies. It is not complicated

to calculate the actual time in another parts of the world but causes sometimes confusion. To simplify this, TIPHON

should use a common time-base to schedule tests. UTC or the InternetTime can be
