PROVISION OF END-TO-END QUALITY OF SERVICE GUARANTEES IN MULTIMEDIA TELECOMMUNICATION

Klara Nahrstedt

   Currently, the telecommunications industry undergoes fundamental changes due to new challenges to support multimedia communication. These challenges come from new media such as audio and video which have very different requirements from traditional data and text information. Particularly, their requirements for quality of services (QoS) and guarantees in end-to-end fashion will need to be satisfied. The reason is that the quality of multimedia delivery over data networks competes with the quality of radio and television services which the users already know and are used to their quality.
In this paper we present services and protocols, concepts and algorithms for provision of end-to-end QoS guarantees in multimedia telecommunication. We present frameworks and possible solutions to the above described challenges and show them on case studies of existing and experimental systems.

Keywords: multimedia communications, multimedia protocols, audio, video, data networks
