1.3.3.1.3 Data Transfer Phase

The data transfer phase enables the transmission of data packets between the RDG client and the target server by using the RDG server as a proxy. In contrast to the use of RPC over HTTP as the transport, when using UDP, the tunnel (2) is a logical entity and the channel is the end-to-end connection between the RDG client and the target server. In addition, a tunnel can consist of only one channel.
