NetNumen U31 network management system is connected to outband management
interface on ZXR10 5250 so that network management information is transmitted
independently from service information.
The advantage is the interruption of service channel doesn’t influence management of
equipment by the network management station. Network management information
transmission is more reliable. The disadvantage is that network management network
built independently is influenced greatly by territory restriction so that extra investment is
necessary.
6.1.2 NetNumen U31 NM System
NetNumen U31 network management system is an integrated router, switch, and CE
management system developed by ZTE. Covering network management, network
management and service management, network management system provides the
following functions:
Failure management guarantees stable network operation
In network management maintenance, the management staff has an urgent need to know
the network operation to make sure the network works stably. Failure management in
NetNumen U31 mainly takes charge of realtime receiving of various equipment alarm
and network event reported by all network elements. It can notify the maintenance staff in
an audible and visual way. The maintenance staff confirms and deals with the event.
They save the collected alarm reports in the base for various statistic and query. Failure
management is the most important and most usual management measure in network
operation and maintenance. With failure management, users can implement query,
realtime monitoring, failure filtering, failure location, failure confirmation, failure clearance,
and failure analysis etc. NetNumen U31 system also provides audio prompt, graphic
display of alarm, accessible alarm box, Email system, and SMS system. It notifies users
with sound and light, Email, and message for users to have easy daily maintenance.
Performance management obtains a complete understanding of network services
Network traffic flow, network load are the most focused concern in network management.
NetNumen U31 performance management module mainly takes charge of performance
monitoring and analysis of network and equipment. It provides maintenance and
management department with information to supervise network engineering, planning
and adjusting to improve network operation quality by collecting various performance
data from network elements and generating performance report after processing. With
performance management, users can perform statistics of equipment load, traffic flow,
and interface load to learn about network service quality, assess and adjust network
resource configuration as soon as possible.
Resource management makes good use of network resource
