Data Network Integrated Centralized Monitoring System Design And Implementation

After the establishment of new China Telecom, the bad consequence of long time mopolization gradually occured as the result of the huge difference that exists between the two absolutely different operation systems: the new pure business operation system and the former political-business operation system. New reforms were carried out to quench the ever growing needs of the tele-comsumers and also for the self-development of China Telecom, in which the reform in Local Network Maintenance System is among the most important ones. This is not only a crucial component of the "Five Centralized Management" of China Telecom Co., but also a necessary choice for China Telecom to realize its ambitious plan to become a competitive force among world-class modern tele-companies.The high speed of development in Telecommunication Networks has bring great convinience to people's life, yet challenges are also advanced in the area of network management and control. A new concept of electrolized operation maintenance management and integrated surveillance. This system use normal computer network platform and the most common operation system Windows. Advanced technologies as MS SQL Server et.al were also used in this system. centralized surveillance and real-time surveillance in Permutation, Transmission, Power Supply, Data, PHS et. al were achieved via data communication technologies.The warning gathering module of this system will use SNMP, ICMP protocals to realize the node warning surveillance and the data extration of performance monitoring datas. Network Time Synchronization will also be achieved by NTP protocal. This design use tri-layer structure. Protocals such as ICMP and SNMP will be used in collaboration of network element interaction in gathering module to achieve the collection of network element information. This module will use multi-thread timer technologies and accomplish tasks as network elementon-off test, network elemnet ports status query, network element ports current rate gathering。The interaction between...
