- As the telecom network is developing continuously in scale and complexity, network management is now playing a crucial role in improving network service quality, streamlining the network resource and lowering the maintenance cost. Therefore, a transmission management system with comprehensive functions and in compliance with unified standards is of profound significance to the service quality and maintenance cost of transmission network. To meet the development of Telecommunications industry, ITU-T (International Telecommunication Union-Telecommunication Standardization Section) proposed the concept of TMN (Telecommunication Management Network). TMN serves to provide an organized architecture and standardized interfaces from the perspective of global telecommunication network, and thus, the management information can be exchanged in a unified manner between different management systems, between management system and telecommunication equipment, and further more, the whole telecommunications network can be maintained and managed in an integrated and standard manner.
- The TMN service management system is made up of BML (Business Management Layer), SML(Service Management Layer), NML (Network Management Layer), and EML (Element Management Layer). Such division is called the TMN management architecture. ITU-T M.3000 Overview of TMN recommendations ITU-T M.3010 Principles for a telecommunications management network ITU-T M.3013 Considerations for a telecommunications management network ITU-T M.3020 TMN interface specification methodology ITU-T M.3180 Catalogue of TMN management information ITU-T M.3200 TMN management services and telecommunications managed areas: overview ITU-T M.3300 TMN F interface requirements ITU-T M.3400 TMN management functions
- The TMN management functions include configuration management, fault management, performance management, security management, and account management.
- SNMP: Simple Network Management Protocol Used to ensure the transmission of management information between any two points It’s easy for the network administrator to retrieve and modify information at any node in the network, detect faults, diagnose faults, plan the capacity and generate reports. There are three versions, SNMP V1, V2 and V3. Currently, SNMPV1 are widely applied to the network.
- Broadband O&M should enable carriers to keep their competitive strength, including: Reduce OPEX OPEX is short for operation expenditure. Reducing OPEX means to improve O&M employees’ working efficiency and reduce the requirements for their professional skills. Fast Provisioning Fast provisioning means to raise the speed in global network and to fast support new services. Satisfy Customers To satisfy customers, carries have to respond to customers quickly and change from passive maintenance to positive maintenance.
- In a word, the access network management faces network deployment, service provision, service assurance and network analysis challenges.
- In the TMN model, the N2000 BMS is at the element management layer, and provides network management interfaces for the upper layer NMS and 3rd party OSS.
- The N2000 BMS employs the standard client/server architecture. The clients and the server are connected through LAN or WAN. The N2000 BMS server communicates with the managed devices in the inband or the outband mode. In the inband networking mode, the N2000 BMS manages network devices through the service channels provided by the managed devices. In this mode, the N2000 BMS and devices exchange messages through service channels provided by the managed devices. In the outband networking mode, the network management information goes through the communication channels rather than the service channels provided by the managed devices to realize the network management networking.
- BMS is based on Huawei iMap unified platform, supports information interaction of every service process through MDP. Whole NM system’s reliance and stability is updated. BMS adopts C/S architecture, supports multi client opertion, and can meet the requirement of big network’s management and deployment. Low coupling modularizing system design is easy to expand. Independent database has high reliance and is easy to be upgraded smoothly. BMS is designed on multi system operations, it support Solairs and Windows. Rich northbound interface.
- Customizing a Working Scene of the N2000 BMS : 1. Components must exist in the new scene. 2. There is no restriction on the number of customized scenes on the N2000 BMS. 3. The default working interface of the customized scene depends on the selected component. Each component has its own default working interface. The working interface of the scene is determined by the priority level of the component. 4. From high to low, the priority levels of components are as follows: NE component, alarm monitoring component, entire network resource value-added component, performance monitoring component, network analysis component, DC component, NE tool component, system maintenance component, security monitoring component, and license management component.
- Based on the working scenarios of users, the N2000 BMS are classified into several subsystems. A specific user can complete all the tasks in one scenario. Network monitoring: Provides the functions such as alarm management, environment monitoring, security monitoring, and performance measurement. Network maintenance: Provides the functions of NE maintenance. Whole-network resources: Provides the functions of whole-network query and configuration. Network analysis: Provides the network analysis functions, including trunk management, line test, and diagnosis. System management: Provides the functions of system configuration, system maintenance, and license management. NE software management: Provides the functions of NE software backup, patch management, and upgrade. In addition, the N2000 BMS provides “My System”, in which a user can define a subsystem according to the requirement. The classification of the N2000 BMS on the one hand helps different O&M employees to devote to the related work while on the other hand satisfy the users’ personal requirement.
- Unified Topology Management 1. Different color identify different status of the Link and node. 2. We can view the whole network. 3. Smooth zoom in and out 4. Visible object filter, filter by background, name, sub-map, link, node type 5. Aerial view for whole network 6. Link and node color represent the real-time status of node and link
- Devices and their links are displayed in the topological view. Subnets and views are provided to organize the objects and show the actual networking architecture. Topology management also provides operation entrance for managing and maintaining the objects in a centralized manner. 1. The topology view displays the devices and their links. 2. The navigation tree in the left pane and the view in the right pane eases the monitoring. 3. The filter tree displays the device concerning the user. 4. The aerial view enables you to browse the whole view and locate the displayed area. The color of an NE reflects its polling status and alarm status. 5. The submap eases the management of the large number of NEs.
- Configuration management involves the service configuration and maintenance for all the devices in the network. The major functions are as follows: The N2000 BMS provides tools and menus, and you can telnet to a device for configuration and maintenance through commands. The N2000 BMS provides graphical menus for configuration and maintenance. You can configure a majority of services through the GUI.
- Device maintenance including the following operations: Resetting a device Opening or closing a shelf panel Querying the details of a device Synchronizing the time of a single device Synchronizing the NE data and the N2000 BMS data automatically Identifying an NE automatically Board maintenanceIt includes the following operations: Adding a board Deleting a board Enabling a board Disabling a board Querying the details of a board Modifying a board Saving data Port maintenanceIt includes the following operations: Displaying the port list Setting the trap switch of an xDSL port Activating or deactivating an ADSL port Looping back an ADSL port or canceling loopback of an ADSL port Activating or deactivating a G.SHDSL port
- The N2000 BMS provides the unified view of the entire network resources through the resource management of the entire network. The N2000 BMS realizes the centralized management and measurement of the resources of the same type and also realizes the batch configuration of devices. In addition, the N2000 BMS provides global profiles which are applicable to all devices of the same type in the entire network. This eases the service configuration.
- A profile is a group of attributes of objects. To ease management, we usually define the common attributes of the objects into a profile. Through profiles, the effort put in handling repeated tasks is reduced and the efficiency is improved. The N2000 BMS manages a large number of user ports. The application of profiles eases the configuration. The N2000 BMS provides many profiles to ease the service configuration.
- The features of the global profile are as follows: Off-line configuration: After global profiles are created, they are saved on the N2000 BMS first. They are not created directly on the devices. Therefore, global profiles can be created when the devices are off line or when the devices do not exist. They are not dependent on the device statues. Globally effective: After global profiles are created, they are valid for the devices in the entire network. Global profiles for one type of devices can be referenced by the devices of the same type, or none devices. Low data repetition: With global profiles, if the profile data of multiple devices is the same, the N2000 BMS keeps only one record. After a device references a profile, the N2000 BMS does not add a new profile record. Instead, the N2000 BMS records the reference information between the device and the global profiles. If the N2000 BMS allows profiles with the same parameters but different profile names. Some profiles with the same parameters may exist on the N2000 BMS, but such profiles are created by N2000 BMS users on purpose. This will not result in much repetitive data. Without global profiles, the N2000 BMS directly records the profile data of all the devices, and there will be a lot of repetitive data. When there are a lot of devices of the same type in some offices, the profile reference table may become very large. However, there is not much data in the table, thus its effect on the performance is very light, and the maintenance is still easy.
- The N2000 BMS works with terminals and supports the function of managing the terminals in a centralized manner.you to reset, synchronize, upgrade, and configure terminals, as well as saving. The terminal manager supports the management of ADSL Modem, G.SHDSL Modem, and ONT.
- In addition to the fault monitoring and handling, the performance of the network is also important to ensure the quality of service. With the popularization of the IP network, the degradation of the performance is not always shown as the decrease of the service completion rate or faulty alarms. Instead, it is shown as the degradation of the quality of service, such as the decrease of the service rate and traffic. In this case, evaluating the quality of service and locating the performance bottleneck through performance data analysis are more accurate and become a necessity. The performance management is an important feature of the N2000 BMS. With this feature, the N2000 BMS provides multiple ways to analyze the running performance through the performance indexes of access devices and BRASs.
- The N2000 BMS supports real-time performance data query and integrated performance management. 1. Create a performance measurement task on the N2000 BMS. 2. Send performance collection command to the device on schedule. 3. The device reports performance data. 4. The performance data is stored in database.
- 1. Task management module enables creation and management of collection tasks. 2. The max task number is 500 and for each task contains average 15 performance index. 3. For each task it would contains up to 1000 performance index. 4. The user is allowed to create, suspend, recover, and modify tasks and set parameters like measured objects and policy period flexibly
- Performance measurement management supports measurement and analysis of the performance data, including time distribution measurement, time distribution comparison. The measurement result can be displayed in the form of diagram or table.
- Fault management is used to monitor the faults in the whole network in real time. Fault management helps the administrator to take measures in time to recover the network operations by the means of alarm measurement, alarm location, alarm re-defining, correlation analysis, remote notification, and so on.
- The N2000 BMS provides various notification methods to help you to obtain the alarm information. These methods are described as follows: 1. Alarm panel The alarm panel is a panel on the client. It displays the alarm status through flashing indicators and statistics. You can monitor the alarms in the network through this panel to learn the alarm severity and the related statistics. 2. Alarm box The alarm box is a device that notifies you of alarms in audio-visual mode. To use the alarm box, connect it to the N2000 BMS server and set the parameters. You can know new alarms and their severities through the alarm box. 3. Alarm speaker The alarm speaker plays sounds to inform you of the current alarm status. To use the alarm speaker, connect it to the N2000 BMS client machine and set the parameters. You can know new alarms and their severities through the alarm speaker. 4. Topology view The topology view is a view that shows the distribution of devices on the client. The device icons in the view indicate the alarm status through their colors and status. You can observe the icons to know whether an alarm occurs on a device, and the severity and status of the alarm. 5. Fault browser The fault browser is a component on the client. You can browse faults in real time through the browser. The N2000 BMS also enables you to query specific alarms, such as event alarms, history alarms, or current alarms.
- The environment and power monitoring of the N2000 BMS realizes the centralized management and monitoring of the environment parameters and power parameters of the whole network. You can monitor the environment parameters such as door control, smoke, water, temperature and humidity. You can also monitor the power parameters such as the status of the current, voltage and the rectifier module.
- In the topology view, you can check the status of a device icon to know if an alarm is raised from this device. You can also browse the alarm details in the topology view.
- You can use the alarm location function to find the physical locations of faulty devices in the topological view. You can use the right-click menu to locate faults in the alarm query window.
- You can record the maintenance experience for future reference. 1. The knowledge database saves fault handling experience, making it easy to share the experience. 2. Alarms trigger relative experience in knowledge database automatically.
- The N2000 BMS manages several devices of various types. In applications, the maintainers have different responsibilities. Different personnel have different responsibilities, such as monitoring, querying, maintenance, and service configurations. Different operations have different effects on the network. Therefore, a strict and secure mechanism is required for allocating different users with different authorities. Authority and domain-based user management consists of: Device management Resource management Fault management Performance management
- The EMS is responsible for the management of networks, devices, and services. A lot of important data are stored in the EMS. The EMS is important for the whole network, hence it should be reliable continuously in 7*24 hours, preventing and resolving different disasters. After a disaster occurs, the EMS should restore the system and services immediately. The N2000 BMS HA system monitors the system software and hardware constantly. In case of hardware or software failure, the application automatically switches over from the active server to the standby server, so as to ensure the reliability of the N2000 BMS HA system. Veritas backup + Watchman/Veritas switchover solution Real-time replication based on volumes Automatic switchover Floating IP address supported
- OSS: Operation Support System BSS: Business Support System SLA: Service Level Agreement
- The SBI is an interface connecting the EMS to other managed NEs.
- Located between the element management system (EMS) and the network management system (NMS), the northbound interface (NBI) of the N2000 BMS supports distributed communications between the EMS and NMS. The NBI is used to activate the automatic feature of the management system, so that you can control the NE resources at the NMS GUI side.
