摘要： PROBLEM TO BE SOLVED: To communication-process a real-time data preferentially without delays, in a communications system that uses a protocol. SOLUTION: Information in a protocol header of a data to be sent/received is defined as a preference determining information for determining whether to send/receive preferentially, and the information to be preferentially processed in the combination of the preference determining information is registered, stored, and controlled as the preference data information. When sending/receiving data, the preference determination information is extracted from the sent/received data to determine, when it is the data registered as the preference data information. If it is the registered data, the data is sent/received preferentially than the data that have not been not registered. COPYRIGHT: (C)2007,JPO&INPIT
