On the website of the Competence Centre for Videoconference Services (VCC), assistance regarding audiovisual communication in the German Research Network (DFN) is provided. The services offered by the DFN contain the video conferencing service DFNVideoConference and the web conferencing service. The DFNInternet service is required for the use of these services.

The DFNVideoConference service is based on the H.32x-protocol suite. In the field, these protocols are H.320 for ISDN- and H.323 for IP-based connections. Furthermore, the service can be used with the SIP protocol.

For these protocols, that were standardised by the ITU/IETF, there is detailed information available. Many major manufacturers (for example Cisco, Polycom, LifeSize, Sony and others) provide solutions and products in this sector, which were tested by the VCC.

The web conferencing service is based on the Adobe Connect product. It is centrally provided and supported by the German Research Network.
