Webinar

Web conferencing refers to a service that allows conferencing events to be shared with remote locations. These are sometimes referred to as webinars or, for interactive conferences, online workshops. In general the service is made possible by Internet technologies, particularly on TCP/IP connections. The service allows real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers information of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or short presentations from any computer.

Web conferencing technologies are not standardized, which has been a significant factor in the lack of interoperability, transparency, platform dependence, security issues, cost and market segmentation. In 2003, the IETF established a working group to establish a standard for web conferencing, called " Centralized Conferencing (xcon)". The planned deliverables of xcon include:

· A basic floor control protocol. Binary Floor Control Protocol (BFCP) published as RFC 4582

· A mechanism for membership and authorization control

· A mechanism to manipulate and describe media "mixing" or "topology" for multiple media types (audio, video, text)
