H.323 Videoconferencing

Internet-based, or IP (H.323), videoconferencing is in use in Europe and Worldwide on a daily basis. 

Welsh Video Network IP Service

During 2002 the WVN began the move towards becoming an IP (and not ISDN) network, built on the existing JANET network, which includes the North Wales MAN and the South Wales MAN.  The JANET Videoconferencing Service - IP (JVCS - IP) became a full service on Monday 17th February 2003.  Documentation to support the service is available here.

UK H.323 Architecture Group

The report of the H.323 Architecture group is now available. This report covers the structure needed to run a UK national IP videoconferencing service and looks at such issues as physical equipment location, addressing, security and QoS requirements. The WVN IP pilot and service will be developed in accordance with the recommendations made in the H.323 Architecture Group's final  report.

European Addressing Scheme - Global Dialling Scheme

The WVN IP service uses an addressing scheme developed in consultation with other European academic networks. This dialling scheme has now been adopted by UKERNA for JANET IP videoconferencing. The dialling scheme has been deployed in a number of partner national research networks beyond Europe, including the United States and has become known as the Global Dialling Scheme.
