A paper on CONFIANCE and DCON has been recently presented at the IPTComm 2007 conference (Principles, Systems and Applications of IP Telecommunications) in New York. After the discussion of the paper, which described the scalability enhancements DCON can offer, a demo of the described work has been successfully arranged for all the interested attendees. You can have a look at all the presented work (slides, proceedings, and a couple of videos as well) on the documentation page (http://confiance.sf.net/doc).
A user-friendly, interactive, installer script for CONFIANCE is now available. It allows an automatic retrieval, compilation and installation of all the needed pieces of the framework (Asterisk, Minisip, BFCP, MSRP, Videomixers and both client and server side patches), without having to take care of each one separately. The script is interactive, which means you can choose what to compile and what not (for example if you've already installed a component). You can get the gz-compressed script from the download page: http://prdownloads.sourceforge.net/confiance/confiance-installer-07.tar.gz?download Just launch it and follow the instructions to build CONFIANCE.
Exciting news in CONFIANCE! The new release introduces support for video mixing and transcoding functionality, so that to provide continuous video presence in conferences. To do so, CONFIANCE can rely on two different videomixers: * CONFIANCE VideoMixer, a work we're carrying on ourselves, and which you can get on the CONFIANCE homepage; * Sergio Garcia Murillo's VideoMixer, an open source videomixer available on http://sip.fontventa.com/. Both the videomixers are optional, and do not depend on each other. This means that you can choose to enable support for both, for only one, or for none if you're just interested in the already provided basic videoswitching. Instructions on how to enable support for the videomixer(s) are provided in the CONFIANCE installation guide. Though both the videomixers are early works and in a beta stage, they both already work quite fine, and have support for a range of codecs. Specifically, the CONFIANCE VideoMixer currently provides: * adaptive layouts according to how many active video sources are feeding the mix; * continuous presence for up to 8 users (this can be easily enhanced by adding new layouts in the code); * a static logo when no video sources are active; * support for H.261, H.263 and H.263+ (QCIF only for the moment, and H.261 support is still quite buggy). Currently, only one global layout is available for all users in the same conference: support for customized layouts will be added in the future. Any kind of feedback and/or comment/suggestion upon the current work will be more than welcome, and will help us enhancing its functionality. To know more about the VideoMixer Sergio Garcia Murillo wrote, visit his website at http://sip.fontventa.com/, and follow the discussion on the Asterisk-video mailing list. That said, you can get the updated release of CONFIANCE, which envisages support these VideoMixers, on the project download page: * http://prdownloads.sourceforge.net/confiance/confiance_wip_server-0.7.tar.gz?download, the server side of the platform; * http://prdownloads.sourceforge.net/confiance/confiance_wip_client-0.7.tar.gz?download, the client side of the platform; and the CONFIANCE VideoMixer here: * http://prdownloads.sourceforge.net/confiance/confiance_videomixer-0.1.tar.gz?download. To get Sergio Garcia Murillo's VideoMixer: * svn co http://sip.fontventa.com/svn/mcu You'll need xmlrpc-c 1.1 to compile it.
An article about DCON has been recently published on the March issue of the IEEE Communications Magazine: A. Buono, S. Loreto, L. Miniero, S.P. Romano "A distributed IMS enabled conferencing architecture on top of a standard centralized conferencing framework", IEEE Communications Magazine vol.45, No 3, March 2007 (requires IEEE subscription or membership) A demo of the DCON framework in action has also been successfully presented at the latest IEEE INFOCOM 2007 conference, the 26th Annual IEEE Conference on Computer Communications in Anchorage, Alaska. You can get the presented brochure from the Documentation page. Coming to the future events, a paper on CONFIANCE and DCON has been accepted at the upcoming IPTComm 2007 conference (Principles, Systems and Applications of IP Telecommunications). Besides the discussion of the paper, which describes the scalability enhancements DCON can offer, a demo of the described work will be presented as well, so in case you're in New Work on the 19th and 20th June pay us a visit! To conclude, a paper more focused on CONFIANCE has been accepted at the upcoming NEW2AN 2007 conference (The 7th International Conference on Next Generation Teletraffic and Wired/Wireless Advanced Networking). The paper will be presented ad discussed in September in St.Petersburg.
