力の低下を招き、さらにはかかるサービス低下が
通信網全体に波及する事態となり得る。 If such congestion is left unaddressed and normal connection operations are continued, the waiting time for processing requests within the local exchange system will increase, and invalid operations will increase due to blockage of resources necessary for exchange operations such as lines and registers. As a result, normal connection operations are adversely affected, leading to a decline in service capability, and furthermore, such service decline may spread to the entire communication network.

う欠点がある。 Conventionally, when an electronic exchange system is configured using a centralized control method using a single data processing device, the degree of congestion of external loads is determined using a complex statistical processing program that monitors the congestion status of processing request loads within the processing device. However, in order to apply this method to a multiprocessor system using multiple processing devices, it is necessary to quantitatively know the degree of congestion of a large number of distributed processing devices, and the program processing Further, there is a drawback that the information transmission path for collecting the degree of congestion of the processing device becomes complicated.
