As shown in Figure 1, the VRP8 management plane adopts a hierarchical architecture, consisting of the following elements:
A configuration interface layer provides various configuration tools. A configuration tool parses a configuration request and then sends the request to a Configuration (CFG) component. The CFG component uses a pre-defined configuration information model to perform verification, association, and generation of configuration data. After a user commits a configuration and the configuration is successfully executed, configuration data is saved in a central database. A process-specific APP database obtains the configuration information from the central database.
The VRP8 supports two-phase configuration validation and configuration rollback.
As shown in Figure 2, the VRP8 implements fault management based on service objects. The VRP8 creates a service object relationship model to analyze the correlation between alarms, filter out invalid alarms, and report root alarms, speeding up fault identification.
As shown in Figure 3, the VRP8 provides a flexible performance management mechanism. Information about an object to be monitored, including a description of the object and a monitoring threshold, can be manually defined on a configuration interface. The configuration data can then be delivered by the central database. The APP component collects statistics about the configured object and sends them to a performance management (PM) module through a PM agent. After receiving the statistics, the PM module generates information about a fault based on the pre-defined object and monitoring threshold and then sends the fault information to the network management system (NMS) through the fault management center. Performance information can be viewed by running a command or through the NMS.
As shown in Figure 4, VRP8 plug-and-play allows a great number of devices to be deployed on a site at a time and to be managed and maintained in remote mode, reducing OPEX.
Devices supporting VRP8 plug-and-play are deployed as follows:
