7 Operation and Maintenance
7.1 NetNumen U31 Unified Network Management
Platform
IP network is going to bear more and more services. At the same time, due to large-scale
network, complicated configuration and high market expectation, network management
and working load become more complicated and bigger. Manual operation and negative
maintenance obviously can not guarantee reliable operation of the entire system.
Maintenance staffs nowadays have to think of the way to arrange fast service deployment
in the network, guarantee reliable network operation, forcast network operation quality
and find out the network failure in the shortest time when problems occur. So active
network monitoring, automatic network failure inspection and settlement must be
implemented to make sure sound network operation and maximum network benefit.
ZTE based upon the time’s call develops NetNumen U31 unified network management
system. Concentrating on multiple products like router, switch, ZXR10 8900E, NetNumen
U31 is an integrated network management system melting network element
management, network management and service management together. It supports
multiple database, graphic interface in multiple languages and convenient operation.
Provding flexible northbound interface, it is capable of powerful interconnection.
7.1.1 Network Management Networking Mode
Inband management and outband management can be used between NetNumen U31
NM system and ZXR10 8900E.
7.1.1.1 Inband Management
For inband management, network management information and service data are
transferred in the same channel without asking for an extra DCN network. NetNumen
U31 NM system only needs to connect with network devices nearby and configure SNMP
parameters.
The advantage of inband management: flexible netwoking and no extra investment.
However, network management information takes up too much bandwidth, which may
seriously influence service quality.
