The growth of the Internet has brought with it a tremendous volume of multimedia traffic, which is bursty in nature. Providing a required QoS as well as modeling multimedia traffic has been a challenging task. In this work, we transcode multimedia data to cater for low bandwidth availability and different end-user requirements. We propose a protocol architecture which has been developed by the amalgamation of well-known components and that would provide guaranteed multimedia communication over the Internet. We model multimedia traffic using the M/Pareto distribution in an attempt to represent realistic traffic pattern. We use semantics of multimedia data-streams for transcoding to avoid network congestion and to ensure optimal use of network resources. The impact of transcoding the multimedia data to suit it to the network load and the end user requirements is also studied. The simulation results are presented and compared.
