2  A platform for enhanced interactive communication  Part of ICT4RD-Tz, started in 2005‏  Each year, several CSD projects at KTH are initiated under ICT4RD-Tz  Aimed at the development of rural areas of Tanzania  In fall 2007, ComCloser project was started to join the rural development in Tanzania Project background

3  Lack of good education leading to poor literacy rates  Lack of health facilities leading to in-born diseases and high death rate Problems addressed

4  An interactive communication platform for accessing quality healthcare and educational services remotely  The ComCloser Platform consists of two prominent features: ◦ Video Conferencing ◦ Shared Workspace Solution

5 Video Conferencing Solution Architecture

6  Server Side ◦ iPath - a healthcare CMS ◦ Moodle - an e-learning CMS ◦ SER - Sip Express Router, used for handling SIP users ◦ MiniSip Launch Application - used to launch conferences ◦ MiniSip Conference Application - handles the conference  Client Side ◦ Browser - a normal internet browser used to visit Moodle and iPath and create conferences ◦ MiniSip - a regular sip soft-phone Architecture components

7  Based on the Remote Framebuffer (RFB) protocol o RFB does not bypass NAT – problem  RFB Server - a host that advertises the service of sharing its desktop  RFB Client - a MiniSip client that connects to an RFB server  RFB Splitter ◦ an application that forwards RFB messages back and forth from the RFB server and Clients ◦ initially thought of forwarding streams ◦ customization of messages for each client encoding compression colour depth Shared workspace solution architecture

9  Integration with MiniSip to solve the NAT problem o currently, a stand-alone solution o add RFB client and server to MiniSip client o add RFB splitter to the conference gui o signalling helps RFB bypass NAT now, fixed ports, not negotiated  Desired end result o user presses button o sharing to all other clients begins Integration with MiniSip

10  Both, video conferencing and shared workspace, somewhat overcome the need of face-to-face communication  Remote access of healthcare and education services  Improvement in the weak healthcare and education sectors of rural areas Benefits

11 Conclusions  We have: ◦ embedded MiniSip conferencing into Moodle and iPath ◦ implemented a stand-alone solution for the shared workspace ◦ investigated future work

12  Improvements to the ComCloser platform: ◦ large scale testing ◦ recording of Media ◦ video on demand for iPath ◦ browser Plug-in for Minisip ◦ extend RFB protocol security to the RFB Splitter ◦ add conferences to Moodle event calendar ◦ merge shared workspace with MiniSip conferencing ◦ enabling recurring scheduling of conferences ◦ make the conferences pick ports on the fly Future work
