Synopsis:

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

Requirements:

Students have to successfully elaborate practical exercises and individual netowking project. The subject will be evaluated as 30 % laboratory exercises, 30 % individual project and 40 % theory examination.

Syllabus of lectures:

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

10.Authentication and authorization infrastructures (IEEE802.1x, RADIUS,

Kerberos, LDAP)

11.Security certificates and their usage (PKI, VPN)

12. Wide area networks based on technologies of Frame Relay and Multiprotocol Label Switching

13. Function of some useful file transfer and sharing protocols - FTP, TFTP, CIFS

14.Framework of the network management (SNMP, MIB)

6.Design of IP routed network - II. network connection,

assignment of IP addresses to individual interfaces, setting of RIP routing, verification of network function

7.Configuration of VPN network with IPsec protocol, verification of communication

8.Assesment

9.Design and verification of function of WiFi network - basic IEEE802.1x

analysis

10th Design of IP routed network - III. network connection,

assignment of IP addresses to individual interfaces, setting of OSPF routing, verification of network function

11st Design of IP routed network - IV. network connection,
