PRIORITY CONTROL METHOD, SWITCH TERMINAL AND PROGRAM THEREOF IN SEMANTIC INFORMATION NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a priority control method in a semantic information network which controls the priority between applications.

SOLUTION: When a client terminal 2-1 sends an event, a packet receiving means 30 in a switch terminal 3 receives the event and transfers it to a packet storing means 31 which then checks the priority of packets according to a priority table and stores the packets in a retrieval queue. A packet fetching means 32 preferentially fetches packets of the higher priority. A receiving party retrieving means 33 matches the event with a filter to determine which client terminal the packets are to be sent to. A transmission packet storing means 34 checks the priority of transmission packets according to the priority table to store them in a transmission queue. A transmission packet fetching means 35 fetches packets preferentially from a transmission queue of the higher priority and outputs them to a transmission packet sending means 36.
