Communication data relay system and method

A relay system relaying communication data transmitted from a client when the client requests provision of an application to one of one or more servers in a network, the network being formed by the one or more servers having the same application and the client, the communication data being exchanged between the client and the one or more servers by being divided into one or more frames, the relay system including

• a preceding apparatus connected to the client and
• a succeeding apparatus connected to the one or more servers,
• the preceding apparatus comprising:
• an obtainment unit obtaining the communication data from the one or more frames transmitted from the client;
• an extraction unit extracting predetermined data from the obtained communication data;
• a determination unit determining predetermined field data corresponding to the predetermined data;
• and
• a transmission unit setting the predetermined field data in the one or more frames and transmitting the set one or more frames,
• the succeeding apparatus comprising:
• a succeeding extraction unit receiving the one or more frames transmitted from the preceding apparatus and extracting the predetermined field data from the received one or more frames;
• a relay destination determination unit determining a relay destination server corresponding to the extracted predetermined field data from among the one or more servers connected to the succeeding apparatus;
• and
• a transmission destination change unit changing a destination of the one or more frames received from the preceding apparatus to an address of the determined relay destination server and transmitting the changed one or more frames.
