VIRTUAL ROUTING DEVICE BASED ON WEB SERVICE AND SYSTEM THEREOF AND INFORMATION RETRIEVING METHOD USING VIRTUAL ROUTING DEVICE, ENABLING CONTENTS PROVIDERS TO EASILY SHARE CONTENTS WITH OTHER SITES

摘要

PURPOSE: A virtual routing device based on a web service is provided to retrieve contents stored in other server if a server does not have requested contents when a client requests the server to transmit the contents, so that the client can use the contents, thereby sharing the contents between service providers. CONSTITUTION: A packet checker(110) filters available packets only, and stores the filtered packets in an input buffer(112). A packet generator(120) receives commands from a CMS, generates different XML packets according to the commands, and stores the generated XML packets in an input buffer(122). A service branching filter(130) receives the XML packets to distinguish the packets. If the packets are to be received, the service branching filter(130) stores the packets in a receiving buffer(140). If the packets are to be transmitted, the service branching filter(130) extracts information on a destination of the packets, and transmits the packets to an output buffer(160) such that the output buffer(160) can transmit the packets to other server.
