Remote Display Protocol (RDP) is a protocol developed by Microsoft that offers an interactive graphical user interface to connect to an external computer using a network connection over a local area network (LAN). The remote user uses RDP client applications for that purpose, while the network connection computer must also run RDP server applications. In simple terms, RDP is an alternative to the classic protocol-based Direct Rendering Display Protocol or DDD. When used with the proper hardware, RDP provides a highly efficient way of transmitting high-quality graphics over a slow or dial-up network.
RDP works based on a powerful client-server model. A typical RDP session has five main phases: preparation, compression, display, data transfer and output (DTR), and last acknowledgment. The client-side of the application will have generic calls like GetPhysicalPort, CreateStream, etc., where it creates and modifies the required ports and then sends them to the remote desktop connection. On the other hand, the server will have generic methods for managing connections like Create Streaming Channel, Creates Remote Control, etc. These methods make it possible to handle multiple RDP connections simultaneously without any loss of quality.
Compression is the key to enabling high-speed data transfers. A compression algorithm takes the analog signal that is sent over the network and makes it smaller. RDP software allows for several types of compression, depending on the physical architecture of the systems that are being used. MP3-type sound files and video clips may be compressed, while audio tracks may only be compressed. In contrast, video clips and standard text or image files may be decompressed according to the requirements of the RDP software and the particular RDP hardware that is being used.
Honest time communication between two or more computers using remote desktop protocol is known as remote linking. To enable this kind of linking, there must be an authenticated remote host that enables synchronization of the linked computers. Remote desktop services that use the RDP can be achieved by using Microsoft Windows Server RDP services that are configured using the Win Socket function in the Microsoft Window Server.
The Win Socket function enables one computer to a remote computer through the Microsoft Windows Server. This happens through the use of the RDP protocol (Real-time Protocol) controlled by the Remote Display Port. The RDP software is usually downloaded into the computers that are to be connected. Then they need to be opened up with the appropriate software loaded on the computer participating in the remote connection.
Remote access and remote management are the two things that are best done using RDP software. Remote desktop sessions can be managed from any location as long as the computers that are being used are connected to the same network. On the other hand, some might want their desktops at home located in different locations. The RDP software can still be connected even if they are not in the same room. The benefit of this feature is that they can work on the same screen and see each other even if they are on different sides of the world.
Remote service provider companies like Sun Microsystems and others use the Real-Time Digital Protocol (RDP) to deliver applications to desktop computers. The delivery capabilities of the RDP can range from mere file and print sharing to video and audio-visual integration. One of the significant benefits of using RDP is the synchronization of the data used by the user on his desktop with that of the remote desktop. With the synchronization of data, the desktops can perform tasks just as they would when they were on the same physical platform.
Aside from transferring data, the RDP can also allow for synchronizing settings and preferences between the two platforms. This is very important in corporate networks that have different localizations. For example, in a South Korean office, each employee is assigned a specific desktop. With the use of the RDP, each desktop can be connected to the Internet, so each individual’s settings and preferences can be synchronized between the two computers.
