NetNumen U31 Integrated NM Platform

IP network is bearing more and more services. At the same time it covers large area with
complicated configuration. Users have high expectation for the network. Network
management difficulty and workload become rather great. Only artificial management
with passive checking maintenance can no long meet the needs of reliable operation of
the network.
How to quickly deploy services in the network, how to guarantee reliable and stable
network operation, how to foresee the network operation quality, and how to detect the
failure point as soon as possible when failure occurs in the network are all present before
OAM staff. Thus active monitoring is urgently needed for the network to automatically
detect and solve network failure, to maintain smooth operation of the network, so as to
realize network value maximization.
To achieve this ZTE developed NetNumen U31 integrated network management system.
NetNumen U31 is an centralized network management system integrating multiple
products of router and switch. It integrates network element management, network
management, and service management in one, supporting multiple databases. It has
graphic interface of many languages, providing direct and easy operation. Offering
flexible northbound interface, it supports powerful interconnection integration capability.

NM Networking

Inband management and outband management can be adopted for networking between
NetNumen U31 network management system and ZXR10 5250.
Inband management
Inband management. Network management and service data are transported through
one channel with no need to build extra DCN network. NetNumen U31 network
management system can perform management when it is connected with the network
equipment nearby with related SNMP parameters configured.
The advantage of inband management is flexible networking without extra investment.
The disadvantage is network management information occupies service bandwidth,
which may influence service quality.
Outband management
Outband management. Network management information is transported inside network
management network, separated from service data. Extra DCN network is needed.
