Abstract:
In a wide area network including a server processing system and a client processing system connected thereto, the client processing system including a processor and computer-executable instructions for enabling the client processing system to access information from the server processing system, a method of reducing latency experienced by the client processing system when accessing the information, comprising the steps of:caching, in a non-volatile memory device at the client processing system, a first set of data representing a first portion of information to be accessed at the server processing system, said first portion representing frequently accessed information at the server processing system;maintaining at the server processing system a record of all data cached at the client system, and in response to a request by the client processing system to access information from the server processing system, transmitting a second set of data representing a second portion of the information from the server processing system to the client processing system, the second portion of the information representing only that portion of the requested information that is not already cached at the client processing system;retrieving at the client processing system the first set of data cached in the non-volatile memory device; andcombining the downloaded second set of data with the retrieved first set of data so as to reduce actual latency, and outputting the combined first and second sets of data to a user of the client processing system.
