Anotace:

Students understand the basic common techniques, protocols, technologies, and algorithms necessary to communicate in computer networks focusing primarily the 2nd to 4th layer of the ISO OSI model. They also get a basic understanding of communication media, security, and network administration. Students will be able to write a simple network application and configure a simple network.

Požadavky:

Programming in C, C++, or Java.

Osnova přednášek:

1. Module requirements and organization. History of computer networks. OSI model.

2. Physical layer. Metallic and optic media - properties, usage, connecting.

3. Link layer: Acknowledging, link layer protocols. Shared media access methods.

4. Network layer. Routing.

5. Interconnecting the networks: hubs, bridges, routers.

6. Transport layer protocols. TCP/IP v4.

7. IPv6: properties, addressing, security, mobility.

8. Flow control, QoS.

9. Directory services: DNS, X.500.

10. Security: principles, symmetric and asymmetric ciphers, digital signature.

11. Network security: rules, firewalls, NAT, ssh, ssl, ipsec, vpn.

12. Special networks: FibreChannel, NAS, SAN.
