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 network availability analysis methods based on a network management system. The methods are applied to the network management system, and one thereof includes the following steps: determining equipment involved in availability analysis, inputting the equipment into the network management system, and generating numbers of the equipment; drawing a topology graph of network links; determining last end equipment on each network link; obtaining user quantities and alarm threshold values of all the end equipment; receiving alarm information and alarm releasing information sent by an equipment end; and determining a network range and a time range, and calculating network availability. The network management system is utilized to realize full network management of the equipment and the links, parameter changes of the last end equipment are used as markers of network interruption, and accurate interruption time data are obtained. By utilizing the methods provided by theinvention, an operator can monitor network status in real time, and can record network interruption reasons and troubleshooting manners in an orderly manner to obtain complete operation data to facilitate continuous improvement of operation service capability.
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...
