Communication system, communication method, and non-transitiory computer readable medium storing program

A communication method comprising:

• at a first receiver of a communication apparatus, receiving a packet;
• at the communication apparatus, processing the packet matching with a predetermined condition by a method associated with the predetermined condition, wherein the predetermined condition is defined by a flow table;
• at the communication apparatus, transmitting a first notification when the packet does not match with the predetermined condition;
• by a communication control apparatus:
• receiving the first notification by a second receiver;
• limiting a rate reception of the packet in receiving the packet at the communication apparatus when an index based on the number of times of reception of the first notification satisfies a first condition;
• causing the first receiver of the communication apparatus to stop receiving the packet when the index based on a number of times of reception of the first notification satisfies the first condition;
• and
• causing the first receiver of the communication apparatus to resume receiving the packet after a predetermined time passes when the first receiver of the communication apparatus stops receiving the packet.

A first non-transitory computer readable medium storing a first program, the first program causing a first processor in a communication apparatus to execute:

• receiving a packet by a first receiver,
• processing the packet matching with a predetermined condition by a method associated with the predetermined condition, wherein the predetermined condition is defined by a flow table, and
• transmitting a first notification when the packet does not match with the predetermined condition;
• and
• a second non-transitory computer readable medium storing a second program, the second program causing a second processor in a communication control apparatus to execute:
• receiving the first notification by a second receiver of the communication control apparatus when the packet does not match with the predetermined condition,
• limiting rate reception of the packet in receiving the packet at the communication apparatus when an index based on the number of times of reception of the first notification satisfies a first condition,
• causing the first receiver of the communication apparatus to stop receiving the packet when the index based on the number of times of reception of the first notification satisfies the first condition, and
• causing the first receiver of the communication apparatus to resume receiving the packet after a predetermined time passes when the receiver of the communication apparatus stops receiving the packet.
