Website Traffic Generation

website Traffic is a flow of data in a communication channel. For example, web traffic is the data that is sent or received by a user's web-browser. During the development of telecommunication systems it is very important to precisely simulate various kinds of traffic generated, for example, by a wireless device. There are two kinds of data networks: circuit-switched and packet-switched. The traffic in the former model is generated constantly (for example, in IS-95 networks a data packet is sent every 20 ms, not depending on whether there is any data to send or not). In the packet-switched networks the traffic has bursty nature, i.e. sometimes there the data is transmitted only if there is something to transmit. There are at least two approaches for traffic generation in packet-switched networks: the 3GPP2 model and the 802.16 model. The 3GPP2 model is much more complex to implement but it is supposed to give more precise results. The 802.16 model is much simpler in realization.
