Aim

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

Learning Outcomes 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 interception)
* 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.


This course should prepare you for starting an exjobb thesis project in this area (for undergraduate students) or beginning a thesis or dissertation (for graduate students).
