Communication system and computer-readable storage medium

A communication system comprising:

• a first communication control apparatus connected between a network connection apparatus and a first client apparatus;
• a second communication control apparatus connected between the network connection apparatus and a second client apparatus;
• and a communication control management apparatus that is connected to the network connection apparatus and manages communication of the first communication control apparatus and second communication control apparatus,
• wherein the first communication control apparatus includes:
• a first processor that generates a first packet including a first virtual tag;
• and
• a first interface that mediates communication between the first client apparatus and the second client apparatus by transmitting and receiving the first packet,
• the second communication control apparatus includes:
• a second processor that generates the first packet including the first virtual tag;
• and
• a second interface that mediates communication between the first client apparatus and the second client apparatus by transmitting and receiving the first packet, and
• the communication control management apparatus includes:
• a third processor that generates a second packet including a second virtual tag and generates a third packet including a third virtual tag;
• and
• a third interface that communicates with the first communication control apparatus by the second packet and communicates with the second communication control apparatus by the third packet,
• wherein the third processor monitors communication based on management information defining regular communication between the first client apparatus and the second client apparatus as communication by the first packet including the first virtual tag, defining regular communication between the communication control management apparatus and the first communication control apparatus as communication by the second packet including the second virtual tag, and defining regular communication between the communication control management apparatus and the second communication control apparatus as communication by the third packet including the third virtual tag.

A non-transitory computer-readable storage medium that stores a program that a first communication control apparatus connected between a network connection apparatus and a first client apparatus, a second communication control apparatus connected between the network connection apparatus and a second client apparatus, and a communication control management apparatus that is connected to the network connection apparatus and manages communication by the first communication control apparatus and second communication control apparatus are caused to execute,

• wherein the program causes the first communication control apparatus to execute
• a procedure of generating a first packet including a first virtual tag;
• and
• a procedure of mediating communication between the first client apparatus and the second client apparatus by transmitting and receiving the first packet,
• the second communication control apparatus to execute
• a procedure of generating the first packet including the first virtual tag;
• and
• a procedure of mediating communication between the first client apparatus and the second client apparatus by transmitting and receiving the first packet, and
• the communication control management apparatus to execute
• a procedure of generating a second packet including a second virtual tag;
• a procedure of communicating with the first communication control apparatus or the second communication control apparatus by the second packet;
• and
• a procedure of monitoring communication based on management information defining regular communication between the first client apparatus and the second client apparatus as communication by the first packet including the first virtual tag, and defining regular communication between the communication control management apparatus and the first communication control apparatus or second communication control apparatus as communication by the second packet including the second virtual tag.
