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)
· A mechanism for notification of conference related events/changes (for example a floor change)
· Webinars are first and foremost best practices
