On the workstation side, a new GUI management client application is developed in Java to offer the similar functionalities as the original one, and a totally new graphic real-time system traffic statistics function is integrated to make it easier for user to monitor system traffic information in real time.   The main object of this project is to study the GPON specifications, and understand GPON system working procedure and traffic transmission principle. On the other hand, ‘original system management application’ study is necessary including third party documentation reading and C code understanding.

This diploma thesis describes a design and implementation of a system for monitoring events in passive optical networks, specifically in GPON networks. The main technologies used in the implementation of this system are Apache Kafka, Docker and the Python programming language. Within the created application, several filters are implemented. This filters obtain essential information from the captured frames in terms of traffic analysis on the given network. The result of the thesis is a functional system that from the captured GPON frames obtains information about the network traffic and stores them in the Apache Kafka, where the stored data is accessible for further processing. The work also provides examples of how to process the stored data, along with information about their meaning and structure.
