IPv6 Videophone with Windows Driver Model By Gopinath Rao Sinniah Asian Institute of Medicine, Science and Technology (AIMST) Current Conferencing Tools WDM Video capture Audio capture QoS and Flow Label IPv6 Address binding Use of Flow Label in IPv6 Types of Communication Videophone using winsock2 Videophone using multicast The flow of packets using WDM and IPv6 Videophone to mobile phone (3G/4G) Current Tools Vic Rat HVIP6 (High-quality Video conferencing platform based on IPv6 multicast) Gnome Meeting Windows for Driver Model (WDM) Advantages of WDM Video Capture 32 bit address Synergy between DirectShow and CSA Single class driver architecture Television tuner, input selection and support for fields One driver for all Windows OS Windows Driver Model (WDM) Video Capture Audio Capture in WDM Audio processing is performed in kernel mode Kernel streaming is built on top of WDM What is QoS A video phone application requires: The cost is not prohibitive There is a network path available to the other party The user knows the IP address of the terminal the other user The end terminals can reassemble the data packets into a sensible order The end terminals understand how to handle errors in packets The packets arrived at the minimum length of time Use of Flow Label in IPv6 header Advantages of using flow label Decreases the average processing load of the network routers Facilitates end-to-end IP level security mechanism Reserving resources using flow label reduce problem caused by frequent route changes Facilitate implementation of QoS based routing The use of 20-bit flow label for QoS Will ensure smooth transition on video and audio packets without degradation Will ensure adequate latency level Requires special handling by routers (a separate project) Still in the implementation level IPv6 Address binding Most of the nodes will have more than 1 IPv6 address Link Local Address Global Unicast Address Choice of source address based on destination address Will inte
