Laboratory exercises in OPNET environmentfor Communication technolgies course

This master’s thesis deals with the design of laboratory exercises for the Communication Technologies course that is included in the second year of bachelor’s degree in Teleinformatics. This course represents first introduction of students with network protocols and technologies, therefore, the thesis deals with just the basic physical technologies, routing protocols and transport layer protocols. The introductory part of the thesis is devoted to theoretical knowledge to particular tasks. For the design of laboratory exercises is used OPNET environment, concretely its unpaid version IT Guru Academic Edition 9.1. The first task is focused on the differences in two basic transport protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The second task is orientated on the differences in the transmission network parameters using wireless networks and Ethernet technologies. In the third task the routing protocols Routing Information Protocol (RIP) a Open Shortest Path First (OSPF) are compared. These are protocols of a group Interior Gateway Protocol (IGP) that are characterized by the usage within a single autonomous system. The last exercise is aimed at Asynchronous Transfer Mode (ATM) and Frame Relay technologies, which are technologies used mainly in networks Wide Area Network (WAN). All devised exercises are accompanied by detailed instructions for students including supplementary questions and tasks leading to individual work and reflection. The thesis includes model solutions to these four exercises and CD where are inserted all programs source codes
