ConferenceXP Architecture

The network architecture for ConferenceXP is peer to peer. The client application uses IP Multicast by default to communicate with other clients in a multicast group called a "ConferenceXP Venue". In addition to the ConferenceXP client, there are several services that are part of the platform:

  • Venue service: Maintains a mapping of venue name to multicast address, and provides a web service which allows clients to discover available venues.
  • Archive service: Backed by SQL Server, the archive service allows a conference to be recorded and played back.
  • Reflector service: In cases where multicast isn't available, the reflector service can bridge clients together using unicast.
  • Diagnostic service: Maintains current send/receive statistics to allow clients to discover in real-time where networking or other problems exist.

ConferenceXP History

ConferenceXP originated in 2001 at Microsoft Research where most of the core development was done. In 2007 Microsoft Research External Research and Programs funded the Center for Collaborative Technologies at the University of Washington to continue work on the ConferenceXP platform and to apply the technologies to a wide range of educational and collaborative scenarios. In 2010, rights were transferred to the OuterCurve Foundation and the Apache Licence version 2.0 was applied.
