Remote Desktop Protocol (RDP)

Remote Desktop Protocol (RDP) is a protocol designed for secure communications in networks using Microsoft Terminal Services. RDP is available for most versions of the Windows operating system as well as Mac OS X, Linux and FreeBSD. In 2006, RDP 6.0 was released for Microsoft Vista. An open source version is under development.

Noteworthy properties of RDP include encryption, smart card authentication, bandwidth reduction, resource sharing, the ability to use multiple displays and the ability to disconnect temporarily without logging off. RDP also allows redirection of functions such as audio and printing. RDP can support up to 64,000 independent channels for data transmission. Data can be encrypted using 128-bit keys. The bandwidth reduction feature optimizes the data transfer rate in low-speed connections. Network administrators can remotely diagnose and resolve problems encountered by individual subscribers.
