|Abstract:||The necessity of monitoring passive optical networks (PONs) is considered. It is shown that the monitoring task is important for preventing network downtime and faults, maintaining fault tolerance and security of information transmission in order to provide the customer service with operational and reliable data on the current and forecasted state of a fiber-optic communication line. The PON architecture is considered, and it is shown that for high-quality network monitoring it is necessary to implement periodic polling of all available OLTs and tracking important indicators: detecting ONUs on OLTs that are not included in the ONU database, or have been registered simultaneously on two OLTs. Algorithms have been developed that allow processing and outputting OLT data structured according to PON specifics: an algorithm for adding a new OLT and obtaining information about ONUs, an algorithm for displaying information about ONUs in real time, and an algorithm for displaying information about client devices in real time. It is shown that in the process of monitoring a PON, an important role is played by data obtained in real time, i.e. on demand. The choice of SNMP protocol for management has been substantiated. The features of the SNMP protocol are analyzed.|
