History of network traffic models

The design of robust and reliable networks and network services is becoming increasingly difficult in today's world. The only path to achieve this goal is to develop a detailed understanding of the traffic characteristics of the network. Demands on computer networks are not entirely predictable. The success of a network depends on the development of effective services. An accurate estimation of network performance is critical for the success of any networks. Performance modeling is necessary for deciding the quality of service (QoS) level. Performance models in turn, require very accurate traffic models that have the ability to capture the statistical characteristics of the actual traffic on the network. Many traffic models have been developed based on traffic measurement data. If the underlying traffic models do not efficiently capture the characteristics of the actual traffic, the result may be the under-estimation or over-estimation of the performance of the network. This would totally impair the design of the network. Traffic Models are hence, a core component of any the performance evaluation of networks and they need to be very accurate.
