[PS3] Computer Networks 3

Main objectives of the course:

By studying the course, the student will gain deeper knowledge about the multimedia IETF architecture and its protocols, which can be used to develop and provide multimedia (not only voice) services as an extension of IP networks.

Student will know:

  • describe the operation of protocols and devices needed to build a VoIP / RTC communication solution
  • design and and practically implement a simple communication VoIP network with connected terminals
  • apply basic measurement and diagnostic procedures in this network aimed at verifying and the operation of the solution (wireshark, dig, tcpdump)

Lectures:

  • Multimedia architecture of IP networks
  • Protocol SIP (Session Initiation Protocol)​
  • DNS (Domain Name System) and ENUM
  • Transport of time-sensitive data and speech transmission in IP networks
  • Problems of communication via NAT devices. Mechanisms of STUN, TURN, ICE. RTP / media proxy. B2BUA
  • Support protocols for providing multimedia services – PSTN cooperation, Instant Messaging and Presence. Programming SIP API
  • Security of multimedia communication
  • Alternative protocols for IMP and voice (XMPP, WebRTC / WebSocket)
  • Basics of protocols according to H.323 recommendation (RAS, H.225.0, H.450, protocols for support of additional services)
  • Quality of service in IP networks

Course requirements:
Continuous assessment / evaluation:
Get the admission to the examination students have to actively participate during the exercises throughout the whole semester and they have to elaborate a semester work.
Final assessment /evaluation:
The condition for the successful completion of the course is to obtain at least 61 out of 100 points for the semester work and passing the examination. The examination consists of the written and oral parts. Tasks will focus on the solving of practical problems as well as on the demonstration of theoretical knowledge. The final evaluation is the result of the sum of interim (continuous) and final evaluations.

Final evaluation:
100-92 A
91-84 B
83-76 C
75-68 D
67-61 E
To enroll for an exam student must have 10 points.
Course outcomes:
Students after the course completion will have a knowledge of IETF multimedia architecture and protocols whose is supporting voice and multimedia services provided over IP networks. Students will:
- understand and is able to describe the functionalities of necessary protocols and entities required for the deployment of a simple multimedia communication solution.
- be able to design and implement a simple multimedia communication solution.
- receive skills and abilities to perform basic measurements and diagnostics steps requried to verify functionalities and the quality of proposed communication solution.
