US 6,185,617 B2 · Construction and usage of a pre-warmed cache for client-server emulator

Abstract

A method of communicating between computers, particularly between a host connected to a network server, and a workstation client running a terminal emulator. A pre-warmed cache is generated, containing information used in common by emulation programs on the client and server. The pre-warmed cache can be loaded on the client, e.g., when establishing a session with the server. The pre-warmed cache may be generated by executing an application on the host, transmitting at least one terminal data stream associated with the application to the server (or to a second server configured substantially similar to the first server) and building a cache instance using one or more portions of the terminal data stream. A single pre-warmed cache can be provided for different hosts.

Claims23

Dependent claims

A method of communicating between at least two computers, comprising the steps of:

generating a pre-warmed cache containing information used by a first program on a first computer;
loading the pre-warmed cache on a second computer for use by a second program which is associated with the first program, said loading step occurring prior to any request for actual use of the information by the second program;
and
establishing a session between the first and second computers using the first and second programs.

1 more element

A computer network comprising:

a plurality of computers, including at least a first computer having a first communications program, and a second computer having a second communications program which is associated with said first communications program;
a communications link for transmitting information between said first and second communications programs;
and
means for loading a pre-warmed cache on said second computer, said pre-warmed cache containing information used in common by said first and second communications programs, said loading means loading the pre-warmed cache on said second computer prior to any request for actual use of information contained in said pre-warmed cache by said second communications program.
