A protocol used by Microsoft Windows NT Server, Terminal Server Edition, and by Windows 2000 Server Terminal Services that lets clients communicate with Terminal Services over a network.
Remote Desktop Protocol (RDP) is based on the T.120 protocol of the International Telecommunication Union (ITU), a standard multichannel conferencing protocol that is also used in Microsoft NetMeeting conferencing software.
RDP is a multichannel-capable protocol that can use separate virtual channels for carrying serial device communication and presentation data sent from the server and encrypted client mouse and keyboard data sent from the client.
RDP supports up to 64,000 separate channels for data transmission and supports multipoint transmission.
RDP is sometimes referred to as the Remote Display Protocol. It was formerly known as the T.SHARE protocol.
