Communication apparatus, information processor, communication method, and computer-readable storage medium

An information processor comprising:

• a CPU configured to execute a predetermined protocol process;
• and
• a communication apparatus which communicates with a partner apparatus through a network,
• wherein the communication apparatus comprises a hardware circuit configured to:
• analyze a transmission frame or a reception frame, the transmission frame being generated by the CPU and being transmitted to the partner apparatus, the reception frame being received from the partner apparatus;
• manage multiple unused-state storage areas in which connection information is stored, in a predetermined storing apparatus accessible by the CPU, and manage storage area discrimination information by which each of the unused-state storage areas is discriminated;
• determine the unused-state storage area in which connection information is stored, from the multiple unused-state storage areas, when a connection establishment request is detected from the transmission frame or the reception frame as a result of the analyzing, the connection information being used while being shared with the CPU;
• and
• notify the CPU of the storage area discrimination information by which the determined unused-state storage area is discriminated.

A communication method to be executed by a communication apparatus for communicating with a partner apparatus through a network,

• analyzing a transmission frame or a reception frame, the transmission frame being generated by an external CPU and being transmitted to the partner apparatus, the reception frame being received from the partner apparatus;
• managing multiple unused-state storage areas in which connection information is stored, in a predetermined storing apparatus accessible by the CPU, and managing storage area discrimination information by which each of the unused-state storage areas is discriminated;
• determining the used-state storage area in which the connection information is stored, from the multiple unused-state storage areas, when a connection establishment request is detected from the transmission frame or the reception frame, the connection information being used while being shared with the CPU;
• and
• notifying the CPU of the storage area discrimination information by which the determined unused-state storage area is discriminated.

A non-transitory computer-readable storage medium having a communication program recorded therein, the communication program, when executed, causing a hardware processor of a communication apparatus which communicates with a partner apparatus through a network, to execute:

• analyzing a transmission frame or a reception frame, the transmission frame being generated by an external CPU and being transmitted to the partner apparatus, the reception frame being received from the partner apparatus;
• managing multiple unused-state storage areas in which connection information is stored, in a predetermined storing apparatus accessible by the CPU, and managing storage area discrimination information by which each of the unused-state storage areas is discriminated;
• determining the unused-state storage area in which the connection information is stored, from the multiple unused-state storage areas, when a connection establishment request is detected from the transmission frame or the reception frame as a result of the analyzing, the connection information being used while being shared with the CPU;
• and
• notifying the CPU of the storage area discrimination information by which the determined unused-state storage area is discriminated.
