  • Key issue: show the behaviour of Mobile IPv6 and its route optimization in a streaming video application. The laptop streams video to the home IPv6 address of the iPAQ. The iPAQ switches between two IPv6 Wirelans LANS while receiving video. Mobile IPv6 ensures via route optimization (using binding updates) that the the laptop always streams directly to the actual address of the iPAQ instead of streaming via the tunnel setup by the Home Agent.
