Embodiment Construction
[0025] The present invention provides a network availability analysis method based on a network management system, which will be specifically described in the form of embodiments in conjunction with the accompanying drawings.
[0026] In this embodiment, the usability is calculated by using the usability analysis method provided by the present invention. The structural diagram of the network link of this embodiment is as follows figure 1 As shown, the devices involved include externally adjusted optical transmitters, EDFAs (erbium-doped fiber amplifiers) and optical receivers. Because through the SNMP network management system, we can monitor the parameters, abnormal status and time information of all devices in the network, but the entire network management cannot be realized, that is, the network where the devices are located, so we cannot completely and accurately judge the service interruption Case. However, on the network management system, the service interruption can ...

The invention discloses a network availability analysis method based on a network management system, which is applied to the network management system and includes the following steps: determining the equipment involved in the availability analysis, entering the equipment into the network management system, and generating the serial number of the equipment . Draw a topology map of network links. Identify the endmost device on each network link. Obtain the number of users and alarm thresholds of all terminal devices. Receive the alarm information and alarm clearing information sent by the device. Determine network scope and time range, and calculate network availability. The network management system is used to realize the whole network management of equipment and links, and the parameter change of the end equipment is used as a sign of network interruption, and accurate interruption time data can be obtained. Using the method provided by the present invention, operators can monitor the network status in real time, record the reasons for network interruptions and troubleshooting methods in an orderly manner, and obtain complete operation data, so as to continuously improve operation service capabilities.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a network availability analysis method based on a network management system. Background technique [0002] Network availability refers to the entire network composed of several network links from the beginning to the end. The quality of network availability is related to whether the communication between devices in these network links is good. The devices include communication devices such as externally adjusted optical transmitters, field receivers, building receivers, or fiber-to-the-home receivers. Network availability refers to the ratio of the time that the entire network can provide uninterrupted services to the total running time. The calculation formula is: network availability A = (total time T in the statistical period - average time Ti of network service interruption) / statistical period The total time in T. The average time of network service interruption Ti...
