Performance analysis of a Token Bucket Shaper for MPEG4 video and Real Audio signal

The modern communication system has made the world a “Global Village” in true sense. However, as the number of users of this communication system is increasing, the challenges are mounting as well. The users send different types of traffic to the network, however it is necessary that the traffic must conform to the specified network parameters otherwise it will be troublesome. In case the sent traffic violates the agreement between the network and the user, then there is a need to regulate it. Traffic shaping plays an important part in the provision of Quality of Service (QoS) guarantee. Token Bucket Shaper, based on Token Bucket Algorithm is used to shape the bursty and random data in order to provide the QoS guarantee. This paper presents the performance analysis of a Token Bucket Shaper for real world data such as MPEG4 video and Real Audio signal. The effect of varying various Token Bucket Shaper parameters on its performance is also discussed.
