Description:

The course builds upon the Computer Networks course (BI-PSI), obligatory for the program. Students will learn in detail principles, protocols, and technologies used in modern computer networks from local area networks up to Internet, with focus on switching, routing, security, and virtualization. The emphasis will be on gaining practical experience with real network devices in the lab and learning important methods of local area and wide area networks from the viewpoint of functionality, performance, and security.

Contents:

1. Principles of construction for virtual local area networks (VLANs).
2. Bridging and Spanning Tree Protocols.
3. Advanced routing: from static to using more than one routing table instances.
4. Interior dynamic routing protocols, OSPF.
5. Network Address Translation (NAT) and Port Address Translation (PAT).
6. Exterior dynamic routing, BGP.
7. Technologies for increasing the throughput of computer networks, MPLS.
8. Multicast traffic: principles, routing, protocols IGMP and PIM-SM.
9. Security policies, traffic monitoring in computer networks.
10. Quality of Services, firewalls, traffic shaping.
11. Multilayer network architectures.
12. Introduction to Software Defined Networks (SDNs).

Seminar contents:

1. Introduction to Cisco devices and lab.
2. Switching, CAM, VLANs, trunking, PV-STP.
3. Static IP addressing on routers, IVR, FHRP.
4. Management VLAN, SSH.
5. Dynamic routing (EIGRP / OSPF) in one area.
6. ACL firewall.
7. NAT and PAT.
8. Multiarea routing, route redistribution.
9. Introduction to GNS3.
10. BGP.
