PROBLEM TO BE SOLVED: To analyze which communication causes congestion in a short time because the congestion can be effectively suppressed by identifying the communication being a cause of the congestion and restricting this communication if the congestion occurs on a communication network. SOLUTION: A counted result for each type of processing which is performed within a unit time immediately before the occurrence of the congestion at the time of occurrence of the congestion is received from individual communication devices N1-N4. The counted result is converted into a processing load for each type of processing by using a processing converting value, and the converted processing load is compared with a prescribed threshold, thereby analyzing the cause of the congestion. By doing this, the cause of the congestion can be automatically analyzed and displayed immediately after the occurrence of the congestion without an operation of an operator. COPYRIGHT: (C)2003,JPO
