7. Objectives, learning outcomes and obtained knowledge

The main goal of the subject is to present the relevant methods and tools required to build and operate different types of IT networks and corresponding network services. The internal structure and operation of network devices are highlighted and the main features and constraints affecting the operation are revealed. Different network platforms, essential network functions and software tools are presented in a practice-oriented way, which are crucial to understand in order to be able to build and operate IT networks.

8. Synopsis
  1. Introduction. Main goals of the semester. Interesting live demonstrations on hot-topic research activities.

  2. Operating Systems of network devices, Linux based platforms (e.g., OpenWRT). Linux systems in details. Packet processing, the exact path of a packet in the system.

  3. Essential software tools (tcpdump, wireshark, iproute2, ifconfig, route, iptables, ...). Python script language and its practical use in networking.

  4. Network functions in practice: DHCP, DNS, ARP, NAT. DHCP configuration, Zero-configuration and its protocols. Different implementations.

  5. Case study: building a virtual test network consisting of Linux based virtual machines step-by-step (NAT, firewall, DHCP, DNS).

  6. Static routing, routing protocols: RIP, OSPF. Connecting the network to the ISP, DNS.

  7. Internal structure and operation of network devices. Routers, managable and non-managable switches, hubs, WiFi access points, optical devices. Interfaces and physical constraints.

  8. Designing and building networks, connecting different devices. Demands, planning the segments, separation, VLANs. Connecting premises to each other. L2VPN, IPSec. Connecting external employees to local networks (remote access VPN), SSL VPN. DMZ design, server placement.

  9. Enterprise WiFi and SOHO WiFi. Authentication in enterprise WiFi networks, protocol 802.1X. Authentication methods. Thin and thick architectures.

  10. Network as a platform. Software-Defined Networking (SDN) concept and implementations. SDN architecture. Different SDN applications.

  11. SDN in practice. Overview of the OpenFlow standard. Software and hardware switches. SDN controllers, case studies.

  12. SDN controllers in details, controller software platforms (POX, NOX, Floodlight, OpenDaylight). Developing controller applications. Rapid prototyping in Mininet network emulation environment.

  13. Multi-path transport, resiliency, load balancing, traffic engineering. Outlook: backbone network technologies, MPLS.

  14. Real networks. Case studies on operational production networks: BMENET, HBONE, GÉANT. Visiting real operating centers.

9. Method of instruction 2 lectures and 1 practice per week
