2.1 Transport

This protocol is designed to operate over dynamic virtual channels, as specified in [MS-RDPEDYC], using the names PNPDR and FileRedirectorChannel.

One active instance of the PNPDR channel serves as a common control channel for adding and deleting devices. Multiple dynamic connections are established on the FileRedirectorChannel channel—one connection for each create-file request (which establishes a file handle) and all corresponding I/O operations made using the file handle.
