METHOD FOR PROCESSING DATA OF TRANSPARENT CACHING SYSTEM USING EXPORTING OF DATA

摘要

PURPOSE: A method for processing data of a transparent caching system using an exporting of the data is provided to increase the speed of data acquisition for a user by reducing the delay of data acquisition, and by enabling a client to directly connect to an original server in case that a cache miss is generated. CONSTITUTION: In case of a cache miss, a user(16) directly connects to an original server(14) and gets data. A layer 5 switch(18) which analyzes a data request packet of the user(16) and extracts URL(Uniform Resource Locator) information is induced. The layer 5 switch(18) performs functions for processing data and communicating with a caching server(12). The layer 5 switch(18) performs functions for maintaining a URL catalog of the caching server(12) and exporting the data. The caching server(12) performs a collection function and an aggregation function of the data. The layer 5 switch(18) maintains URL catalog information stored in the caching server(12). A cache URL entry is deleted periodically. The cache URL entry is deleted using an expire time.
