Telecommunication industry is growing fast due to broad development of telecommunication and computer network technologies.
In this study course students acquire knowledge about architecture and working principles of telecommunication and computer networks. An explanation of ISO OSI 7-layer reference model and TCP/IP protocol stack comparison is provided. Students learn computation principles of Ethernet transmission medium, local computer network design, development and virtualization. Students also gain an understanding of different network types - local, metropolitan, territorial, their differences and available transmission technologies. Students learn how to protect a computer network against loops by using Spanning Tree Algorithm (STA) and STP protocols. The course also introduces students to computer network logical addressing, routing process in packet switched networks and routing table creation. Students evaluate and compare best route calculation algorithms of different routing protocols. This course also contains an overview of transport layer protocols (TCP and UDP) operation and comparison. An introduction to VoIP. Students are able to evaluate QoS parameters and required resources. Network management and administration, troubleshooting principles and tools.
It is intended for this course to be implemented as lessons, that includes lectures, online demonstrations, discussion and practice works.
