Practical Voice Over IP (VoIP): SIP, and related protocols

Practical Voice Over IP (VoIP): SIP, and related protocols

This course will give both practical and general knowledge concerning Voice over IP. The emphasis will be on the underlying protocols.

Following this course a student should be able to:

  • Understand the relevant protocols (particularily SIP, SDP, RTP, and SRTP): what they are, how they can be used, and how they can be extended.
  • Enable you to utilize SIP in Presence and event-based communications
  • Understand how SIP can provide application-level mobility along with other forms of mobility
  • Understand how SIP can be used to facilitate communications access for users with disabilities (for example using real-time text, text-to-speech, and speech-to-text) and to know what the basic requirements are to provide such services
  • Understand SIP can be used as part of Internet-based emergency services and to know what the basic requirements are to provide such services
  • Contrast "peer-to-peer" voice over IP systems (i.e., how they differ, how they might scale, what are the peers, ...)
  • Know the relevant standards and specifications - both of the protocols and of the requirements (for example, concerning legal intecept)
  • Understand the key issues regarding quality-of-service and security
  • Evaluate existing voice over IP and other related services (including presence, mobile presence, location-aware, context-aware, and other service)
  • Design and evaluate new SIP based services
  • Read the current literature at the level of conference papers in this area.
    • While you may not be able to understand all of the papers in journals, magazines, and conferences in this area - you should be able to read 90% or more of them and have good comprehension. In this area it is especially important that develop a habit of reading the journals, trade papers, etc. In addition, you should also be aware of both standardization activities, new products/services, and public policy in the area.
  • Demonstrate knowledge of this area both orally and in writing.
    • By writing a paper suitable for submission to conferences and journals in the area.

Examination *

  • PRO1 - Project, 7.5 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade *

Practical Voice Over IP (VoIP): SIP, and related protocolsA written report:
o The length of the final report should be ~7-8 pages (roughly 3,000 words) for each student
o The report should clearly describe: 1) what you have done; 2) if you have done some implementation and measurements you should describe the methods and tools used, along with the test or implementation results, and your analysis.
o The topic for the paper should be selected in consultation with the instructor.
Language: the report can be written in Swedish or English - (better feedback may be available if the report is written in English)

Aim

This course will give both practical and general knowledge concerning Voice over IP. The emphasis will be on the underlying protocols. After this course you should have some knowledge of these protocols: what they are, how they can be used, and how they can be extended. You should be able to read the current literature at the level of conference papers in this area
As with the Internetworking course you may not be able to understand all of the papers in journals, magazines, and conferences in this area - you should be able to read 90% or more of them and have good comprehension. In this area it is especially important that develop a habit of reading the journals, trade papers, etc. In addition, you should also be aware of both standardization activities, new products/services, and public policy in the area.
You should be able to write papers suitable for submission to Globecomm or other conferences and journals in the area. This course should prepare you for starting an exjobb in this area (for undergraduate students) or beginning a thesis or dissertation (for graduate students).

Syllabus

This course will focus on the protocols associated with Voice over IP. The course should give both practical and more general knowledge concerning these protocols. One of the major aims of the course is that student should be able to build upon these protocols to enable new services.
The course consists of 10 hours of lectures, and an assigned paper requiring roughly 50h of work by each student.

Grading

To get an "A" you need to write an outstanding or excellent paper.
To get a "B" you need to write a very good paper, i.e., it should be either a very good review or present a new idea.
To get a "C" you need to write a paper which shows that you understand the basic ideas underlying mobile and wireless networks and that you understand one (or more) particular aspects at the level of an average master's student in the subject area.
To get a "D" you need to demonstrate that you understand the basic ideas underlying mobile and wireless networks, however, your depth of knowledge is shallow in the topic of your paper.
If your paper has some errors (including incomplete references) the grade will be an "E".
If your paper has serious errors the grade will be an "F".
If your paper is close to passing, but not at the passing level, then you will be offered the opportunity for "komplettering", i.e., students whose written paper does not pass can submit a revised version of their paper (or a completely new paper) - which will be evaluated; similarly students whose oral presentation is unacceptable may be offered a second opportunity to give their oral presentation. If a student fails the second oral presentation, they must submit a new paper on a new topic in order to give an oral presentation on this new topic.
