1. Titel of workshop: Secure realtime audio/video communication - H.350
& encryption & gatekeeper/proxy - using H.323 (...and a little bit SIP)

2. Organizer/Chair: Kewin Stoeckigt (MPG), Egon Verharen (SURFnet)

3. Objectives: At the beginning, an introdution (~ 40 minuts) to H.323
is given, which includes the communication model, current security
issues (e.g. firewalls), the zone concept (GDS) and the gatekeeper/proxy
solution for bypassing a firewall. After this introduction Egon will
give a lecture (~ 40-45 minutes) about H.350 Directory Services
Middleware for Multimedia Conferencing- advantages, implementation,....
In the first hour of the second time slot (~ 60 minutes) participants
are going to install gnugk or KOMProxy (an opensource gatekeeper/proxy)
and configure it with Proxy and GDS and how to setup H.350 for
authentication and directory services. At the end of the day, everybody
should be able to take a gk/proxy home, either on CD or PC. The last 30
minutes will then be used to give a report about the current status of
peering H.323 and SIP, which means, how both techniques can communicate
with each other (right now).

4. Target audience: APAN Members interested in setting up (H.323)
videoconferencing services and who need a quick and free solution for
security/firewall issues, as well as authentication issues.

5. Expected number of participants: 30-40

6. Preferred time: IF POSSIBLE NOT AT THE SAME DAY AS THE SIP SESSION

7. Number of sessions: 4

8. Candidate session chairs and speaker:
- --- Kewin Stoeckigt - H.323 theory - MPG
- --- Egon Verharen - H.350 - SURFnet
- --- ...
- --- ...

9. Remarks (including special arrangements if any):
Will need 40 LAN ports around the table with power. We can use the
Laptops Stephen Kingham is using for his sessions. Other global
Gatekeeper and LDAP Server(s) (SURFNet, IPP, (AARnet??))
