3.11 NetNumen U31 R22 Unified Network ManagementSystem

The IP-based network will carry more and more services. At the same time, the networkmanagement is becoming more difficult with increasing workload, service deployment,complicated configurations, and user demands. Manual management and passivemaintenance cannot meet the requirements of the entire system for reliable operation anylonger.

How to rapidly deploy services in the network, ensure reliable network operation, foreseethe network operation quality, and find a fault in the shortest period when the network isimproper. All these questions require active network monitoring so that network faults canbe automatically detected and resolved, the network can operate properly, and the networkvalue can be maximized.

ZTE develops the unified NetNumen Network System to meet these requirements.NetNumen is integrated with NE management, network management, and servicenetwork management, supports various databases, and has easy-to-use GUI in multiplelanguages. Further, NetNumen provides flexible northbound interfaces and stronginterconnection and integration capabilities.

l Network Architecture

NetNumen is a network management system based on the data communicationnetwork. It can maintain and manage various network devices in a large andcomplicated application environment. Both in-band and out-of-band managementcan be used between the NetNumen and ZXR10 M6000-S.

à In-band management

In this mode, network management information and service data are transferredin the same channel, and no extra DCN network is needed. NetNumen can beconnected to only the nearest network device and can performmanagement afterSNMP parameters are configured.

In-band management features an flexible network architecture, without, extrainvestment. However, network management information occupies a band widthso that service quality may be affected.

à Out-of-band management

In this mode, network management information is transferred in the NMS networkindependent of service data, requiring extra DCN network resources. NetNumenis connected to the out-of-band management ports of the ZXR10 M6000-S sothat network management information and service information can be transferredindependent of each other.

3-21



In out-of-band management, service channel interruption does not affect theNMS management on devices and the network management information is morereliable. However, the individually structured network is restricted by areas andrequires extra investment.

l NetNumen NMS

The NetNumen NMS is a system developed by ZTE to manage ZTE devices in acentralized mode, including NE management, network management, and servicemanagement.

The NMS provides the following functions:

à Fault management, which ensures stable network operation.

In network management maintenance, maintenance personnel need to know thenetwork operation status. The fault management function of NetNumen receivesvarious device alarms and network event reports from all NEs. These alarms andreports can be presented to maintenance personnel in visible and audible forms.Maintenance personnel confirm and handle the faults and save the collectedalarms or reports in the database so that users can collect and query variousalarms.

The fault management function is the most important management methodfrequently used in network operation maintenance. With this function, users canquery the operation status of the, monitor faults in real time, and filter, locate,confirm, clear, and analyze faults.

NetNumen further provides voice prompt messages and presents graphicalalarms. It can also access the alarm box system, E-mail system, and SMSsystem to inform alarms to users in voice, light, E-mail, and short messages.Users can know the network status in multiple ways and perform dailymaintenance.

à Performance management enables users to know the network service status.

Network traffic, network flow, and network load are most concerned problems innetwork management. The performance management module of the NetNumenmonitors and analyzes the data network and device performance. Performancedata is collected fromNEs and processed to generate performance reports, whichprovide information for maintenance and management personnel, guide networkprograms and planning, regulate the network, and improve the network operationquality.

With performancemanagement, users can collect statistics about the device load,traffic flow, and interface load, know the network service quality, evaluate andregulate network resources configuration.

à Resources management enables reasonable use of network resources.

The resources management system manages physical resources and logicalresources. It is the basic system in operators' service flow and decides theautomation of service flows such as service provisioning and service insurance.

3-22


Chapter 3 Features

With resources management, users can know the management statuses ofdevices, boards, interfaces, and links, and know the usages of logical resourcessuch as VLAN resources, L2/L3 VPN resources, and MAC addresses.

à View management enables users to be clear about the network operation statusat a glance.

View management provides a unified network topology and multi-viewmanagement so that users can observe the network topology of the entirenetwork and network device operation status from the views. Further,view management provides an entry for network and device operation andmaintenance.

With view management, users can know the network device operation status andalarms, and can be navigated to other management systems rapidly.

à Configuration management enables users to deploy services rapidly.

Configuration management configures including device management, interfacemanagement, layer-2 feature management, MPLS management, routingprotocol management, software upgrade management, and configurationfile management. NetNumen supports end-to-end configuration, batchconfiguration, and wizard configuration, and provides default configurationtemplates for corresponding management functions.

à Security management ensures network security.

Security management is used to ensure that users use the system lawfully andmanages users, user groups, and roles.

By properly configuring the relationship between users, user groups, and roles,security control is provided for operators' security management operations.Avoids invalid users accessing the system through login authentication. Providessecurity control for operators' operations through operation authentication.

à Northbound interface enables integration.

With the development of telecommunication services, a network operatormanages different NE-level NMSs or professional network-level NMSs.Professional NMSs cannot exchange information with each other, and variousmanagement contents and operation windows obviously limit the development ofthe network management. To improve global management of telecommunicationenterprises, an NMS workstation is used to perform unified management andcontrol on different interconnected networks to implement global comprehensivemanagement.

The comprehensive NMS and professional NMS are connected throughinterfaces. The professional NMS needs to provide a standard open northboundinterface for the comprehensive NMS so that the two NMSs can be integratedeasily.

The NetNumen supports various northbound interfaces, such as CORBA, SNMP,TL1, XML and FTP.
