Psychology, Ergonomics &
Acceptance of VC-Services
3. What is "Multimedia Conferencing"? (IMTC Definition)
Multimedia conferencing revolutionizes vital, everyday tasks such as
corporate management, training and communication between
geographically-dispersed teams. This technology enables interactive, live
sharing of audio, video and desktop applications during a conference
session. Multiple users participating from geographically distant locations
can collaborate on an application and share visual information while they
discuss a project together. Internet voice and video and PSTN video
increase productivity and reduce travel time and cost, while offering a
personal mode of communication. Applications are wide-ranging and
include investor relations, telemedicine, distance learning, technical design
reviews, and other collaborative activities.

Outline of talk

• ViDe
• GDS – Global Dialing Scheme
– How does it work?
– Who is responsible?
– Dialing examples



ViDe

• ViDe stands for Video Development Initiative
• Hosted at University of North Carolina at Chapel Hill
(UNC)
• ViDe belongs to the Internet2 initiative
• Was founded by several representatives of
universities and educational networks
• ViDe wants to deploy digital audio and video in
research and higher education
• Numerous workgroups doing “active” research in
different areas, e.g. data collaboration, streaming, etc.



ViDe

• Virtual network, based on the H.323 standard
– Network consists of several zones (more about zones later)
• ViDe comprised several autonomously managed
H.323 gatekeeper around the world
– Management of IP traffic
– Get “your personal videonumber (E.164)”
– Allows interaction with MCU (multipoint conference units;
needed if more than 2 systems want to communicate with
each other)



GDS – Global Dialing Scheme
• GDS is a numbering plan for videoconferencing
systems, MCU conferences, gateways and other
audio/video communication related systems
• GDS is similar to the telephone numbering scheme
– IAC (International access code): 00
– CC (country code): e.g. 36 for Hungary, 49 for Germany,
etc.
– OP (Organization prefix): e.g. 200 for KFKI, 893299 for
IPP Garching
– EN (Endpoint number): e.g. 2011 for P. Giese, 6004 for U.
Schwenn
– An E.164 number (~ GDS number) consist of
<IAC><CC><OP><EN>



• GDS uses a hierarchy of
gatekeeper
• Each gatekeeper represents
one zone
– A Zone is a pool of
videoconferencing systems,
belonging to one Organization
prefix
– It does not matter, if
videoconferencing systems
are on the same network; they
can be widespread




• Several research network provider, like NIIF, DFN,
etc. host country gatekeeper who represent the
country code (CC)
• Those CGKs are connected to the world gatekeeper,
owned by the Welsh Video Network, University of
Wales, Ireland

Outline of talk
• The Problem – A short introduction
• GnuGK – The OpenSource solution
– Why GnuGK?
– How does it work?
– A few features
• ViDeNet & GDS
• Authentication schemes
• …
– Security aspects
– Statistics
• Summary & Acknowledgement



The problem – a short introduction
• Complexity of media streams
– Several udp and tcp streams, e.g.
• Q.931, H.245, H.225.0 are tcp (control) streams
• Video and audio data are encapsulated in udp packets
– Amount of data per second
• A vc connection with 512kbit/s send approx. 90 udp packets with an average
packet size of 750 bytes per second
• Dynamic Port allocation
– H.323 uses a few fixed ports, e.g. 1719/tcp , 1720/tcp
– Per connection approx. 6 to 8 ports needed
– Ports are negotiated dynamically during the connection setup
• Used port range: > 210 & < 216 (1024-65535)
• How do you open ports (on a firewall) if you don’t know them?



The problem – a short introduction

• “Blocked” communication or what happens if…
– Setup (often) can pass firewall, but audio and video
data are blocked
– Standard scenario: external (unprotected) client gets audio
and video, but internal (protected) system gets nothing



GnuGK – The OpenSource solution

• Why GnuGK?
– It’s free (GPL)
– It runs on Linux…also free (Windows/Mac version also
available)
– It’s a combination of a regular gatekeeper and a proxy
– Fully H.323 v.4 compatible
– 100% compatible to ViDeNet & GDS



GnuGK – The OpenSource solution

• How does it works?
– Videoconferencing system communicates only with the proxy
– ALL data, tcp data (control channels, etc.) as well as audio
and video data (udp) are transmitted via the proxy



…just a few features…
• ViDeNet & GDS
– GnuGK can be fully integrated into the existing ViDeNet &
GDS (Global Dialing Scheme) structure → dialing of E.164
numbers rather than IPs
– E.g. Gatekeeper in Garching has Zone 0049893299 → it is
easier to remember an E.164 number: 00498932996004 instead
of 130.183.2.60
• Authentication schemes
– Many different authentication methods available, e.g. H.350
(LDAP), mySQL authentication, Radius authentication (incl.
billing)



…just a few features…
• Proxy can be fully/partial deactivated, simply by setting

[Proxy] [Proxy] [Proxy]
Enable=0 Enable=1 Enable=1
• Port range (H.245, Q.931, T.120, RTP) can be limited
InternalNetwork=10.10.2.0/24

– This limits the amount of concurrent calls
– May cause problems with MCU conferences
• NATed endpoints are supported
• Call queuing/forwarding
• Load balancing



Security aspects

• Firewall “just” open for gatekeeper/proxy → all
videoconferencing systems are protected by the firewall
and can’t be hacked/attacked
• System is as secure as any other system on the public
internet
• Everything you have to “protect” is the gatekeeper/proxy
– Switch off all unnecessary services, e.g. www, ftp, ssh (from
outside)
– Install all security fixes/patches



Security aspects

• NOTICE: ALL SYSTEMS CAN BE
HACKED/ATTACKED AS LONG AS THEY ARE
CONNECTED TO A NETWORK/INTERNET/etc.



Statistics (I)
• GnuGK is used for ALL videoconferences in IPP/RZG
(intern↔intern, intern↔extern, extern↔intern,
extern↔extern)
• System is in use since 08/02
– Until 04/04: 1.6 GHz PIII, 256GB Ram, SuSE Linux 7.3
– Since 05/04: IBM X3-35 eServer, 4 x Intel Xeon 2.8 GHz,
1.5GB Ram, RedHat 9
• Breakdowns (“old gatekeeper”) so far:
– 2003: 2 breakdowns (1 x Kernel Panic, 1 x power failure in
building)
– 2004: 2 breakdowns (1 x failure of power supply, 1 x harddisk
crashed → System was replaced by new GK)



Statistics (II)

• ~ 1000 calls per month (~ 40% multipoint)
• Connection speeds from 512kbit/s up to 3MBit/s
(single connection)
• ~ 120GB monthly data throughput
• “Old” system was up and running for 239 days, more
than 7000 calls were handled, about 2000 came from
external institutions, e.g. KFKI, other EFDA
members, MCUs, etc.
• We were not able to “force” proxy down

Future of H.323
Some (Technical) Conclusions
• Desktops: “ViaVideo” for Linux, MACs no topic, VRVS, AG unknown
Either stand-alone or MS solutions
• IM-Messenger: The whole business is afraid of MS (mice & cat…tiger);
SIP is standard & supported by RadVisions MCUs now;

• H.264: H.264 by Tandberg, Sony & Polycom, ITU in 06 / 2003
High-Resolution Video Conferencing this year

• Multipoint: MPG - MCU at DFNVC working since April 29, 2003
NIIF - MCU working since April 29, 2004

H.323 will be the only VC Infrastructure
commercially supported & generally applicable
for several (>4) years
Let’s use it!


Current RZG - Projects
• Administration, Scheduling, TMS, Lotus, Outlook?
• IPP - Gatekeeper, Proxy -> DMZ (2/2004)
• Expanding Infrastructure for MPG & HGF
• Recording VC + PPT (with d-Lecture, test operation)
http://www.d-lecture.de/demo/

• Streaming (possible with Polycom, Sony &Tandberg)
• QoS Control (DFN / RZG / AWI Project)
• WebConferencing not yet recommendable
(Tests FVC CTM / Polycom WebOffice 8-9 / 2003)
• Access Grid (DEISA 2004) Same Drawbacks as VRVS
• Students from TUM & FHM, Practica, Diploma
• Collaborations: DFNVC, HGF, EFDA, ViDeNet, Industry



Psychology, Ergonomics &
Acceptance of VC-Services
Relative Importance of
1 IP-Technics – Hardware, Networking, Firewalls
2 Facilities – Audio, Video, Presentations / Applications
3 User-System Interfaces – Media Control
4 Interoperability between different rooms AND persons
5 Acceptance of the whole system by users
is often mixed up, especially by scientists and even more by
experimentalists, tending to concentrate on tec-problems.

Due to our experience the order from a users point of view is
(from most important psychological to technical necessities):
5>4 >3 >2 >1
Video Conferencing is a just another Service!

„New“ Labs should start with „Bosses / Small Meeting Room approach


Proposal for VC in EFDA
(Bosses, small meetingrooms)
(1) Bosses desks
„T 1000“ (or similar) for Bosses desktops
Or ViaVideo (requires tests and probably manpower)
(2) Small Meeting Rooms
„T 1000“ (or similar) for Bosses desktops
Or „Viewstation“ for small meeting rooms
(3) Firewalls
GNU Gatekeeper-Proxy and Cisco firewall solutions available
(4) MCU
MCU Service via IPP-MPG-DFN, KFKI-NIIF available now, financing
beyond 2005 to be settled
(5) Interface with VRVS/Mbone (in particular for JET TF work)
In parallel all above H.323 clients should be tested whether they
work with VRVS-Mbone
We help the VRVS Slovakia team in testing of their improved
VIC
