What protocol does RDP on Windows 7 use for copying files via the clipboard?

When I copy a local file and paste it to a remote computer through an RDP session (both clients are Windows 7) is it transferring the file data via SMB, SFTP, or some other protocol/port? I've poked around the RDP GUI and don't see any clear reference to clipboard transfer protocols or ports. Just curious.

RDP is its own protocol, and clipboard sharing is provided by it.

From the Remote Desktop Protocol spec:

Clipboard mapping
Users can delete, copy, and paste text and graphics between applications running on the local computer and those running in a remote desktop session, and between sessions.

You can also get a full paper on the RDP protocol from MSDN here. The PDF describes the protocol in terms of the bare-bones protocol, the archive of PDFs supplies papers for the individual services that sit on top of it.
