(Through years of IP network construction, China Unicom has built an IP metropolitan area network and access network covering 13 locations. The network equipment includes a large number of high-end routers and Ethernet switches. With the continuous construction and expansion of IP networks, the importance of network management is becoming more and more prominent. It requires a comprehensive network management system to comprehensively manage IP network equipment and realize centralized management functions such as fault management, performance management, and resource management of network equipment. , in order to guide the expansion and construction of IP networks with the latest network technologies and management methods, and provide strong support for the rapid development of IP services. With the proliferation of all-network data devices, under the premise of lack of monitoring and maintenance means, only relying on simple tools such as remote login and mrtg to monitor and manage the network can no longer meet the requirements of the modern network management model of "centralized monitoring, centralized maintenance, and centralized management". need. In order to improve the management and maintenance capabilities of the network, provide effective management and maintenance means for business realization and implementation, and comprehensively improve the service quality of data services, China Unicom timely proposed to build an IP metropolitan area network management system as soon as possible. Purpose: Two-level management: The enterprise can monitor and manage all IP network equipment; each branch enterprise can monitor and manage IP network equipment within its jurisdiction; . Cluster grouping: The network management must be able to implement various cluster grouping functions based on different business attributes and different regions. Through the construction of the IP metropolitan area network management system, China Unicom will have the ability to connect with the backbone IP network management system unified by the group enterprises in the future to realize end-to-end network management.)
