1.2 Product CharacteristicsThe U2000 improves the capability of managing converged networks, scalability, and ease of use to construct a customer-centered and future-oriented NMS of a new generation.

Centralized Network Management

The U2000 manages transport equipment, access equipment, and IP equipment in a centralizedmanner. Specifically, it manages Huawei products and services of the products. The productsinclude MSTP, WDM, OTN, microwave, and PTN equipment, routers, switches, MSANs,DSLAMs; the services include FTTx, firewall services.

In addition, the U2000 manages end-to-end (E2E) services across domains in access and bearer networks, as shown in Figure 1-2 . The services include SDH, WDM, microwave, packet, PTN,CX, and switch services.



1-3


18/333

Figure 1-2 Centralized network management

Multiple Operating Systems

The U2000 is developed based on the integrated management application platform (iMAP) of Huawei. It supports Sun workstations, PC servers, Sybase databases, SQL Server databases, and

Solaris, Windowsoperating systems (OSs).The U2000 is a stand-alone application that can be installed on different OSs and databases.Hence, it is compatible with multiple OSs. The U2000 provides high-end solutions for large-scale networks and low-cost solutions for small- and medium-scale networks.

Leading Scalable NMS ArchitectureBy adopting the mature and widely-used client/server (C/S) architecture, the U2000 supportsdistributed and hierarchical database system, service processing system, and client applicationsystem and it also supports concurrent operations of multiple clients. Modularized architectureis scalable so that the U2000 meets the management requirements of complex and large-scale

networks.l The U2000 uses an object-oriented, multiprocessing, modularized, and componentized

architecture design, thereby decreasing the degree of the coupling of NE managementcomponents. In this way, the U2000 supports smooth online increase in managementcapability from a single domain to multiple domains.

l The U2000 has the capability of flexibly integrating NBIs.l The loose coupling framework supports the independent upgrade and maintenance of

subsystems.

Visualized Managementl Service supervision:

– Supports service-centered visualized supervision and the function of querying affectedservices by alarm.

– Provides abundant detection and diagnosis methods based on services to quickly check service connectivity and locate faults.

– Supports service-based performance query, threshold pre-warning, and trend analysisin the GUI.

l Service deployment:– Provides templates to set service-related parameters once instead of setting parameters

repeatedly.– Supports bulk deployment of services, increasing the configuration efficiency.– Calculates static routes and allocates labels automatically, without manual intervention.

l Object relationship:– Associates services with tunnels and tunnels with routes. Hierarchical object

relationships represent the bearer relationships explicitly.– Provides bearer relationships to quickly locate and rectify faults.

l Network-wide clock:– Supports the automatic discovery of clocks (1588 clock, synchronous Ethernet clock,

and SDH clock) and addition of the clocks to the clock topology view.– Provides the unified topology view of network-wide clocks and refreshes the tracking

relationships and synchronization status of the clocks when faults occur in networks.– Monitors clock status and displays clock alarms, tracking relationships, and protection

status in real time.

Cross-Domain E2E Service Provisioning l Supports E2E TDM service provisioning and management across traditional microwave

and MSTP networks, which speeds up network deployment and service provisioning of alarge number of microwave services.

l

Supports E2E packet service provisioning and management across IP microwave and PTN/Hybrid MSTP networks, which accelerates service provisioning in an IP network.

l The Veritas volume replicator (VVR) is used to duplicate the U2000 data on the primary

site to the secondary site so that data is synchronized between the primary and secondarysites in real time.

l The Veritas cluster server (VCS) is used to monitor the system and application service inreal time. When a fault occurs in hardware or software, the VCS restarts or stops theapplication service.

l The Veritas volume manager (VxVM) is used to manage the disks and data volumes of servers.

2.2 External InterfacesThe U2000 offers abundant northbound interfaces (NBIs) that help to achieve unifiedmanagement of transport, IP, and access equipment, fast integration between OSS and theU2000, and better quality of customer service. Currently, NBIs jointly developed by Huaweiand mainstream OSS vendors are widely used by 72% of the top 50 carriers worldwide.

In addition to conventional NBIs such as SNMP, CORBA, and TL1 NBIs, the U2000 offers theXML NBI that is based on the MTOSI 2.0 standards. The XML NBI provides multiple extensiblefunctions, including alarm management, inventory management, performance management,service provisioning, and diagnosis test. By using these interfaces, the U2000 can integrate withthe OSS in a fast and holistic manner. Figure 2-4 shows the functions of external interfaces.

2.2.2 SBIUsing the southbound interface (SBI), the U2000 can connect to NEs and manage them. TheU2000 supports the following SBIs: SNMP, CLI, Qx, SSH, and Telnet SBIs.

Qx Interface

Qx interfaces are simplified interfaces based on the Q3 interfaces defined in ITU-Trecommendations. They are used for private communications. Qx interfaces use a protocol basedon standard TCP/IP packets. Qx interfaces support data transmission over media such as in-bandDCCs or ECCs and out-of-band channels, featuring low overheads, standard structures, and highefficiency. Qx interfaces are classified into Qx4 interfaces and Qx5 interfaces (Qx4 is the earlier version). Qx4 interfaces are used for managing the OptiX 2500+ and earlier transport equipment;Qx5 interfaces are used for managing transport equipment later than the OptiX 2500+. TheU2000 can adapt to various protocols.

The U2000 uses Qx interfaces to connect and manage transport equipment, such as MSTP,WDM, RTN, PTN, and OTN equipment.

SNMP SBI

The SNMP SBI is used to connect and manage SNMP equipment.

The U2000 supports the SNMP SBI that complies with the SNMP v1/v2c/v3 standard. Throughthe SNMP SBI, the U2000 can be connected to Huawei routers, switches, and security accessequipment.

SNMP is a TCP/IP-based network management protocol at the application layer. SNMP usesthe UDP protocol at the transmission layer. Through the SNMP SBI, the U2000 can manage thenetwork equipment that supports proxy processes.

Telnet/SSH Telnet (STelnet) SBI

The Telnet and STelnet SBIs are a basic type of interface used for remote login to andmanagement of NEs. The Telnet and STelnet SBIs compensate the disadvantages of the SNMPSBI and allow the U2000 to perform more management functions. Through the Telnet and

STelnet SBIs, the U2000 can be connected to Huawei routers, switches, and security equipment.l Telnet is a TCP/IP-based network management protocol at the application layer. Through

the Telnet SBI, you can log in to an NE in the CLI and run commands directly in the CLIto maintain and configure the NE. Using the TCP protocol at the transmission layer, theTelnet protocol provides services for network communication. The Telnet protocoltransmits communication data in plain text, which is not secure.

l Similar to Telnet, Secure Shell (SSH) is also a TCP/IP-based network management protocolat the application layer. The SSH protocol, however, transmits encrypted data. Using theTCP protocol at the transmission layer, the SSH protocol encrypts data at the applicationlayer. The SSH protocol ensures the security of network communications by means of authentication, encryption, and authorization. The SSH protocol supports authentication

by password and RSA. In addition, the SSH protocol transmits compressed data, whichspeeds up the transmission.



2-13


34/333

TFTP/FTP/SFTP SBI

The TFTP, FTP, and SFTP SBIs are used for backing up NE data, upgrading NE software, andloading patches. TFTP, FTP, and SFTP are TCP/IP-based network management protocols at theapplication layer and are dependent on the UDP protocol.

l Trivial File Transfer Protocol (TFTP) is a basic and standard protocol that requires leastextra overheads, as compared with FTP and SFTP, to upload and download files. The TFTP

protocol does not support password configuration and transfers file contents in plain text.l File Transfer Protocol (FTP) is a set of standard protocols used for transferring files on

networks. The FTP protocol transfers passwords and file contents in plain text.l SSH FTP (SFTP) uses the SSH protocol to provide secure file transfer and processing. For

data backup using the SFTP protocol, passwords and data are encrypted duringtransmission.

Syslog SBIThe Syslog SBI serves as an interface for the U2000 to receive system logs from NEs. With theSyslog SBI, the U2000 can manage NE logs.

4.2 Networking Mode Between the U2000 and NEsThe U2000 adopts the widely used C/S architecture. In such architecture, the client and the server communicate through the LAN or wide area network (WAN). The U2000 server communicateswith its managed NEs in inband or outband networking mode.

4.2.1 Inband Networking ModeIn inband networking mode, the U2000 uses the service channels that are provided by themanaged equipment to transmit messages for network management and manage the network.The messages are transmitted between the U2000 and the equipment through the servicechannels of the managed equipment.

4.2.2 Outband Networking ModeIn outband networking mode, the U2000 uses the communication channels that are provided bythe equipment other than the managed equipment to transmit messages for network managementand manage the network. Generally, the management interface on the control card of themanaged equipment functions as the access interface.

4.2.1 Inband Networking ModeIn inband networking mode, the U2000 uses the service channels that are provided by themanaged equipment to transmit messages for network management and manage the network.The messages are transmitted between the U2000 and the equipment through the servicechannels of the managed equipment.

Figure 4-3 shows an example network in inband networking mode.


Product Description


Issue 05 (2010-11-19)


45/333

Figure 4-3 Example network in inband networking mode

Networking DescriptionThe equipment managed by the U2000 is all connected to the managed network. The U2000needs to be connected to only the nearby equipment on the managed network. After configuringthe related routes, you can manage all the equipment on the network.

The way of connecting the U2000 with the managed network depends on the distance betweenthe U2000 and its nearby equipment. If the U2000 and its nearby equipment are in the sametelecommunications room, you can connect them in LAN mode. If the U2000 and its nearbyequipment are far from each other, you can connect them in private line mode. In this case, the

private line mode is similar to the outband networking mode.

l Networking advantages: The inband networking mode is flexible and cost-effective. It doesnot need extra equipment.

l Networking disadvantages: When a fault occurs in the network, the communication channel between the U2000 and its managed network is broken. As a result, you cannot maintainthe managed network on the U2000.

4.2.2 Outband Networking ModeIn outband networking mode, the U2000 uses the communication channels that are provided bythe equipment other than the managed equipment to transmit messages for network managementand manage the network. Generally, the management interface on the control card of themanaged equipment functions as the access interface.

In outband networking mode, the U2000 can be connected to the managed equipment in multipleways. For example, the U2000 can be connected to the managed equipment through the datacommunication network (DCN), E1 lines, or routers. This topic considers the DCN as an exampleto describe how the U2000 manages equipment. Figure 4-4 shows an example network inoutband networking mode.



4-5


46/333

Figure 4-4 Example network in outband networking mode

Networking descriptionThe equipment managed by the U2000 is all connected to the managed network. The U2000

connects with the equipment on the managed network through the DCN that is made up of other equipment. In this manner, the U2000 manages the network and equipment.

l Networking advantages: In outband networking mode, the U2000 is not connected to itsmanaged equipment directly but is connected to its managed equipment through other equipment. Compared with the inband networking mode, this mode provides more reliableequipment management channels. When managed equipment is faulty, the U2000 locatesinformation about the faulty equipment in a timely manner and monitors the equipment inreal time.

l Networking disadvantages: In outband networking mode, the U2000 manages equipmentthrough a maintenance channel that is independent of the service channel. To provide sucha maintenance channel, you need to construct a network that is made up of extra equipment.

Thus, the cost of constructing the network is high.
