Abstract: There are provided a policy-based extensible markup language (XML) document print management method and system, using a policy object defining a print layout and an access authority to output data, on the basis of the information of a user requesting to print the XML document. The policy-based XML document print management method includes (a) requesting a policy object defining a printing layout and an access authority to output data to a policy management server, on the basis of information of a user requesting to print the XML document, in a policy agent; (b) receiving the policy object from the policy management server, interpreting the policy object, and obtaining policy information, in the policy agent; and (c) printing the XML document using the policy information, in the policy agent. Therefore, it is possible to determine a printing layout of an XML document and print the XML document, according to policy information.

Abstract: A router for supporting differentiated qualities of service (QoS), and a fast Internet protocol (IP) packet classification method performed in the router, are provided. The router hierarchically divides a memory having flow tables into a fast internal cache memory and an external typical memory. The internal cache memory stores recently searched table entries. The router preferentially searches the flow tables of the internal cache memory. Only when the internal cache memory searching fails, the flow tables of the external memory are searched. Consequently, the frequency of interactions between a packet classifier and the external memory decreases to improve the speed of packet classification.
