Design And Implementation Of Traffic Statistic Subsystem Of The Network Management System Of Large-scale Exchange

In the operating of telecom network, the Traffic Statistic Subsystem of the Network Management System of Large-scale Exchange has deficiencies in handling heavy traffic, which reduces the instantaneity and accuracy of Traffic Statistic. At the same time, the database is overloaded due to frequent call of the traffic statistic system, which also affects the stability of the database.This paper mainly discusses the above problems. Firstly, the Network Management System of Exchange is analyzed and the framework of Traffic Statistic Subsystem is designed according to Traffic Statistic Theory. Then, the function of memory pretreatment is provided and search arithmetic of CCB is presented. Besides, improvement has been made to the origin data processing mechanism and report forms generation mechanism of Traffic Statistic System. Finally, a Traffic Statistic Subsystem is designed and implemented based on SP30iEx Exchange, which makes the statistic of the report forms more timely and accurate, and solves the overload of the database due to the frequent call to the database.
