Implementation of HDLC protocol in network simulators
Polášek, Jaromír ; Mašek, Pavel (referee) ; Pokorný, Jiří (advisor)
This diploma thesis deals with the possibility of using HDLC (High-Level Data Link Control) protocol for communication and addressing of smart metering devices with a data concentrator. The HDLC protocol is used in two DLMS/COSEM (Device Language Message Specification/Companion Specification for Energy Metering) communication profiles. To simulate these communication profiles, the most appropriate simulation program is selected. Using this simulator, the first communication profile is implemented and the second one is designed. Communication profile based on TCP/IP (Transmission Control Protocol/Internet Protocol) has been fully implemented. To implement the three-layer HDLC communication profile, all options have been thoroughly explored. Using these findings, a process was designed to guide the full implementation. For the first communication profile the qualitative parameters are measured, which are then plotted and evaluated.

Realizace komunikačního profilu a uživatelského rozhraní pro generátor síťového provozu
Bilka, Rudolf
This diploma thesis deals with the design and implementation of a communication profile and user interface for already created software core of the network traffic generator. Author introduces the reader to possibilities of creating user interfaces in programming language Java, including a brief evaluation of them. Further, the available low-level tools for network traffic generation are analyzed. Based on the requirements specification is then designed and implemented user interface of the generator, which allows you to manage communication profiles and run individual tests over them. Finally, the project is economically evaluated and future development trends of the application are proposed.
