If you are +already familiar with Remote Frame Buffer, you can safely skip this +chapter. + + + +The high level implementation of a system using the Remote Frame +Buffer protocol is known as Virtual Network Computer, or more often +just as VNC. + + + +Remote Frame Buffer (or RFB for short) is a simple +protocol for remote access to graphical user interfaces. It works at +the frame-buffer level, which roughly corresponds to the rendered +screen image, which means that it can be applied to all windowing +systems (including X11, &MacOS; and &Microsoft; &Windows;). Remote +Frame Buffer applications exist for many platforms, and can often be +free re-distributed. + + + +In the Remote Frame Buffer protocol, the application that runs on the +machine where the user sits (containing the display, keyboard and +pointer) is called the client. The application that runs on the +machine where the framebuffer is located (which is running the +windowing system and applications that the user is remotely +controlling) is called the server. &krfb; is the &kde; server for the +Remote Frame Buffer protocol. &krdc; is the &kde; client for the +Remote Frame Buffer protocol. + + + +It takes a reasonable amount of network traffic to send an image of +the framebuffer, so Remote Frame Buffer works best over high +bandwidth links, such as a local area network. It is still possible to +use &krfb; over other links, but performance is unlikely to be as good. + + + + Using &krfb;
