In a communication system, a management node includes: a high-order count value holding unit holding a high-order count value; and a high-order count value distribution unit updating the high-order count value under a high-order update condition and distributing the updated high-order count value to normal nodes. In the communication system, a normal node includes: a count value holding unit holding a count value; a low-order update unit updating a low-order count value held in the count value holding unit under a low-order update condition; and a high-order update unit updating a high-order count value held in the count value holding unit to the high-order count value distributed from the management node together with a reset of the low-order count value.
