Data processing apparatus, data processing method and computer-readable medium

A method for processing data performed by an apparatus having a plurality of modules connected with each other and processes a packet having identification information, the method comprising:

• storing first identification information as a waiting ID and second identification information as a transmission ID;
• receiving a first packet and processing data included in the first packet, the first packet having the same identification information as the stored waiting ID
• generating a second packet for storing the processed data and the stored transmission ID as identification information;
• and
• transmitting the packet, wherein the transmitting transmits the packet having a latter processing order by comparing identification information included in the first packet received by the receiving with identification information included in the second packet generated by the generating,
• wherein the transmission ID indicates an assigned value for enabling identification of order relationships of the plurality of modules.

A non-transitory computer-readable storage medium that stores a program for controlling an apparatus having a plurality of modules connected with each other and processes data, the program executes steps of:

• storing first identification information as a waiting ID and second identification information as a transmission ID;
• receiving a first packet and processing data included in a packet, the first packet having the same identification information as the stored waiting ID;
• and
• generating a second packet for storing the processed data and the stored transmission ID as identification information;
• and
• transmitting the packet, wherein the transmitting transmits the packet having a latter processing order by comparing identification information included in the first packet received by the receiving with identification information included in the second packet generated by the generating,
• wherein the transmission ID indicates an assigned value for enabling identification of order relationships of the plurality of modules.

An apparatus having a plurality of modules connected with each other and processes a packet having identification information, a module comprising:

• a storage unit configured to store first identification information as a waiting ID and second identification information as a transmission ID;
• a reception unit configured to receive a packet;
• a processing unit configured to process data included in a packet, among packets received by the reception unit, having same identification information with the first identification information stored in the storage unit;
• a generation unit configured to generate a packet including the processed data and having the second identification information stored in the storage unit as identification information;
• a buffer unit configured to buffer a packet, among packets received by the reception unit, having identification information different from the first identification information stored in the storage unit;
• and
• a transmission unit configured to transmit a packet having a latter processing order by comparing the identification information included in the packet generated by the generation unit with the identification information included in the packet buffered by the buffer unit,
• wherein the transmission ID indicates an assigned value for enabling identification of order relationships of the plurality of modules.
