SOAP and REST XML Web servicesand generic C/C++ XML data bindings. Ports connus. In this example, UDP is implemented on top of RPL. The client starts sending information (location of the player) via udp and opens a thread for that client (tcp and udp). This feature allows a single sent packet (datagram) to be to received by multiple peers on the same network. The C# Server is multithreaded so we can connect more than one Client program to the Server.
