Product Overview


Network Management Trend

With the development of IT and IP technologies and the convergence of various industries (such as telecommunications, IT, media, and consumer electronic industries), the telecommunications industry has witnessed tremendous changes. Broadband services, mobile services, and network convergence have become the mainstream. Carriers' market orientation and business modes have also changed.

  • The development of the all-IP architecture is a leading factor in the transition from the existing vertical network that is divided by technology and service to the flattened horizontal network.
  • Improving user experience, lowering operation expenditure (OPEX), and improving efficiency are the driving forces for fixed-mobile convergence (FMC).
  • Network convergence leads to operation and maintenance (O&M) convergence.

The U2000 is future-oriented and provides unified management of all-IP and FMC bearer and access equipment.

  • The U2000 supports not only unified management of multi-domain equipment but also unified management at the element and network layers. The U2000has revolutionized the layer-based management mode to meet the management requirements for transforming from the existing vertical network to the flattened horizontal network.
  • The U2000 is a unified network management system (NMS) for multiple domains that aims to minimize O&M costs and to bring more network benefits to carriers.

Product Positioning

The U2000 is an equipment management system developed by Huawei. It is also a major future-oriented network management solution that provides powerful element management and network management functions.

In the TMN hierarchy, the U2000 is located at and supports all the functions of the element management and network management layers. Figure 1 shows the position of the U2000 in the TMN hierarchy.

Highlight Features


The U2000 improves its management capability, scalability, and usability to construct a unified and customer-oriented next-generation NMS.

Unified and Abundant NBIs

The U2000 provides various operating support system (OSS) integration solutions with unified and abundant NBIs based on mainstream standards.
  • Unified NBIs enable the U2000 to manage transport equipment, access equipment, IP equipment.
  • Based on international standards, the NBIs of the U2000 are inexpensive to develop, economical to maintain, and easy to expand.
  • Abundant NBIs (XML, CORBA, SNMP, TLI, TEXT, Customer OSS Test and Line Test) address the needs for OSS integration.

Unified Network Management

The U2000 manages transport equipment, access equipment, IP equipment in a unified manner. Specifically, it manages Huawei MSTP, WDM, OTN, RTN, router, switch, ATN, PTN, MSAN, DSLAM, FTTx, firewall equipment and services.

In addition, the U2000 manages end-to-end (E2E) services, as shown in Figure 1. The services include MSTP, WDM, RTN, PTN, ATN, Router, and Switch services.

Figure 1 Unified network management 
NOTE:Services marked blue can be managed by the U2000 and services marked yellow cannot be managed by the U2000.

The U2000 is also capable of managing third-party equipment by obtaining equipment information directly through ICMP and SNMP protocols.

For details about the third-party equipment management function, see Third-Party Router Management.

Leading Scalable NMS Architecture

By adopting the mature and widely-used client/server (C/S) architecture, the U2000 supports distributed and hierarchical database systems, service processing systems, and client application systems. Modularized architecture is scalable so that the U2000 meets the management requirements of complex and large-scale networks, as shown in Figure 2.

  • The U2000 uses an object-oriented, multiprocessing, modularized, and component architecture design. The degree of coupling NE management components is reduced with this design, which means that the U2000 can increase its management capability from a single domain to multiple domains when the U2000 is installed multi-domain components.
  • The U2000 can flexibly integrate different NBIs.
  • The loose coupling framework supports independent upgrades and maintenance of subsystems.
  • The U2000 enables users to log in to a server at the same time from multiple clients. Users on different clients can view the same network data or custom network data, and operate the clients at the same time.

 Overview of functions and features of the U2000

Function or Feature


Unified network management

The U2000 provides unified GUI-based management for Huawei NEs in the transport, IP, access domains (GUI is short for graphical user interface). It is a unified network management system (NMS) that offers comprehensive functions in managing NE and network alarms, security, performance, topology, logs, inventories, reports, and databases. In addition, it can obtain third-party equipment information using the SNMP protocol to manage third-party equipment. This function meets the requirements of network convergence and rapid development of customer services.

Local craft terminal (LCT)

The U2000 provides an LCT to manage and maintain the plug-and-play function of IP NEs and some transport NEs.
  • The U2000 LCT is an NE layer management system for the optical transport network. The U2000 LCT uniformly manages OptiX series optical transmission equipment from Huawei, such as MSTP, Metro WDM, LH WDM, LH WDM (NA), PTN and submarine equipment.
  • U2000 Web LCT is an NE layer management system for the transport network. The Web LCT uniformly manages OptiX series optical transmission equipment from Huawei, such as the OSN 9560, NG WDM, NG WDM (NA), RTN and submarine equipment.
  • U2000 IP LCT can generate scripts by using configuration templates and planning tables, and deploy the scripts to NEs in batches. This improves efficiency of making scripts.

For more information, see the latest iManager U2000 LCT V200R015C50 Product Documentation released at

Centralized task management

Centralized task management is an NMS task management mechanism that manages and coordinates all scheduled tasks in a unified management GUI. Two types of tasks are managed in the centralized task management mode: system scheduled tasks (periodic) and custom scheduled tasks (one-off). The two types of tasks can run automatically at a scheduled time. Users can set parameters and browse the task status, progress, and results.

NE template management

NE template management allows users to bulk configure NEs by using configuration templates. This makes NE configuration faster and easier. A large amount of repetitive and labor-intensive data entry for NE configurations can be avoided by using templates that automatically fill in the parameter values of the NEs.

NE data configuration and management

During NE data configuration, the U2000 supports bulk configuration of NE services by using configuration templates, importing data sheets, and loading configuration files. During data management, the U2000 supports the backup, restoration, and synchronization of NMS data and NE data. With this function, services can be provisioned quickly in the GUI.

License management

The U2000 provides an intuitive and easy-to-use NE license management window.

License management allows users to query, apply for, and adjust licenses (in the event of a change in capacity or servers). By setting licenses, users can perform the operations required by the service scenario.

Client auto install and update (CAU)

The CAU function enables the U2000 client to install and upgrade automatically through the Internet provided that the U2000 server functions properly and communicates successfully with the U2000 client.

Smooth upgrade

The U2000 can be upgraded smoothly without service interruption, including version patch installation, rollbacks, and cross-version upgrades. After the upgrade, the NE status, basic services, and routing relationships are checked and a check report is generated. This helps to ensure the proper operation of major services immediately after the upgrade and achieve timely detection of issues such as data loss.

Online Help

The Online Help is displayed if users press F1 when using the U2000. It provides comprehensive help information and supports quick information searches. The help information is also available in offline mode.

The management capability of the U2000 depends on the U2000 system itself and its hardware performance.

The key technical specifications include the number of equivalent NEs, number of clients, and number of physical NEs. The management capability of the U2000 in a network that consists of different types of NEs is affected by the following factors:
  • The management capability refers to the maximum number of equivalent NEs that can be managed by the U2000. The management capability depends on the hardware and varies with the hardware configuration.
  • If a client also runs on the computer where the server is running, the management capability is reduced by 50%. Running the client and server on different computers is recommended.
  • The system limits the number of physical nodes, which in turn limits the management capability.
Table 1 U2000 management capability




Related to Hardware

Management capability

Number of managed equivalent NEs

Maximum: 20,000 equivalent NEs


Number of managed clients

Maximum: 100 clients

The number of clients can reach 300 by deploying multiple desktop service (DS) instances on the U2000 that manages only access equipment.


Number of managed physical nodes

Maximum: 15,000 physical NEs

  • The maximum of managed MDUs in access networks is 60,000.
  • There is no limit to the number of subnets. The maximum of physical nodes in each subnet is recommended to be 500; 200 is optimal. The maximum of subnet nests is recommended to be 6.


Number of managed ONTs

Maximum: 3,000,000 ONTs

If the U2000 manages only access NEs, the number of managed ONTs is not restricted to the maximum number of manageable equivalent NEs, 20,000.


Service capability

Number of managed SDH trails

Maximum: 300,000 SDH trails


Number of managed WDM trails

Maximum: 150,000 WDM trails


Number of managed IP service access interfaces (SAIs)

Maximum: 1,000,000 IP service access interfaces (SAIs)


Number of managed tunnels

Maximum: 100,000


Number of managed sites (single-point services, such as VRF and VSI)

Maximum: 300,000


Table 2 shows the simple calculation methods of the maximum management capability on different network scales in FTTH, FTTB/C, and MSAN/DSLAM scenarios. (The maximum management capability is calculated based on lines, that is, ports.) If multiple scenarios exist on the actual network, the management scale in each scenario needs to be converted to the number of equivalent NEs and then summed up.
