Communication system and communication method

A communication system having a plurality of terminals connected through communication networks and using protocols for sending or receiving data, comprising:

• means for segmenting the send data into at least leading data and second and following data;
• means for deciding whether the received data are priority data or not by use of priority decision information of a protocol header of the segmented leading data;
• means for storing a table having data segment identifiers of headers of receive data made to correspond to priority or not;
• means for deciding with said table whether or not the data segment identifier of the received second or the following segmented data is of priority;
• and,
• means for priority-controlling a send or receive process depending on decision results of the table decision means;
• wherein the priority decision information comprises one of the following, a service identifier and
• a network address of the protocol header information and a protocol type of the protocol header information.

A communication system having a plurality of terminals connected through communication networks and using protocols for sending or receiving data, comprising:

• means for making use of priority decision information for deciding the data to be subjected to prior send or receive process as protocol header information in the send or receive data;
• means for registering as priority data information priority decision information of the data to sent or received with priority, the priority decision information having a priority process level added thereto as priority process order;
• means for fetching priority decision information from the send or receive data before deciding whether or not the data are registered as the priority decision information, the data being processed to send to or received from the communication network;
• and,
• means for making priority control of send or receive process of the registered data at the registered priority process level of the priority data information or unregistered data at a priority process level registered in advance;
• wherein the priority decision information comprises one of the following, a service identifier and
• a network address of the protocol header information and a protocol type of the protocol header information.

A communication method in a system having a plurality of terminals connected through communication networks and using protocols for sending or receiving data, comprising the steps of:

• making use of priority decision information for deciding the data to be subjected to prior send or receive process as protocol header information in the send or receive data;
• registering as priority data information priority decision information of the data to sent or received with priority;
• fetching priority decision information from the send or receive data before deciding whether or not the data are registering as the priority decision information;
• and,
• making the send or receive process of the data registered as the priority decision information prior to data being not registered;
• wherein the priority decision information comprises one of the following, a service identifier and
• a network address of the protocol header information and a protocol type of the protocol header information.

• priority-controlling a send or receive process depending on the decision;
• and
• wherein the priority decision information comprises one of the following, a service identifier and
• a network address of the protocol header information and a protocol type of the protocol header information.

A communication method in a system having a plurality of terminals connected through communication networks and using protocols for sending or receiving data, comprising the steps of:

• making use of priority decision information for deciding the data to be subjected to prior send or receive process as protocol header information in the send or receive data;
• registering as priority data information priority decision information of the data to be sent or received with priority among the priority decision information in advance as priority data information, the priority decision information having a priority process level added thereto as priority process order;
• fetching priority decision information from the send or receive data before deciding whether or not the data are registered as the priority decision information, the data being processed to send or to received from the communication network;
• making priority control of send or receive process of the registered data at the registered priority process level of the priority data information or unregistered data at a priority process level registered in advance;
• and
• wherein the priority decision information comprises one of the following, a service identifier and
• a network address of the protocol header information and a protocol type of the protocol header information.
