Annotation
The aim of the course is to familiarize students with current trends in the switched local networks and the key functions of routing protocols in IP networks. The second part of the course introduces students to concepts of ensuring the information security in the communication networks. An integral part of the course is also an explanation of the principles
for ensuring the adequate quality of services in data networks and
features of some file sharing application protocols. The course is aimed rather primarily practically then theoretically
Study targets
The students will master a design of the small scale data networks including a basic security measures.
Course outlines
1.Basic function of Ethernet switches, the technical implementations
of the switching MAC tables (CAM table and Hash function ), understanding the concept of the switched virtual LAN (VLAN)

2.Design of the switched Ethernet LAN, a special supporting protocols (like Spanning-tree) and providing the quality of services in Ethernet LANs

3.Architecture of routing and switching components in data networks. Optical switching and optical networks.

4.Routing algorithms and techniques (Dijkstra, Ford-Fulkerson, deflection routing, Fuzzy routing). Routing algorithms in data networks (vector, link state). Function of RIP routing protocol

5.Function of OSPF and BGP routing protocols

6.Integrated and differentiated model for ensuring quality of service in IP networks

7.The protocols for multicast registration and multicast routing (IGMP and PIM)

8.Security of data networks (IPsec, TLS / SSL), the normal types of attacks and actions against them

9.Methods and security protocols for data exchange in wireless WiFi
networks
