Abstract
A method and system of operating a remote terminal by a terminal server caches representation data of glyphs to be displayed to reduce the amount of glyph data transmitted through a network connection. The remote terminal stores a fragment cache for caching fragments and glyph caches for caching individual glyphs. Each entry in the fragment cache contains data indicating where the glyph data for the glyphs of the fragment are stored in the glyph caches. When the terminal server receives a request to display a text fragment on the remote terminal, it checks whether that fragment is cached at the remote terminal. If so, the terminal server sends a fragment index to the client identifying the entry in the fragment cache for that fragment. The terminal client retrieves the information in the fragment cache entry and the glyph cache and displays them on the remote terminal.
