Abstract

Modern telecommunication networks are complex systems composed of devices from various manufacturers (Cisco, Huawei, HP, MikroTik, and others). In such environments, the Link Layer Discovery Protocol (LLDP), defined by the IEEE 802.1AB standard, is considered the primary tool for automatically discovering and monitoring network topology. This thesis analyzes the implementation of the LLDP protocol across different vendors, the impact of proprietary extensions on interoperability, and the challenges of standardizing data into a unified format.
