Traffic Model Characterization of an HFC Network
This paper describes the traffic model developed to represent the traffic observed on the telecommunication network of a cable operator providing data services. The operator network is based on a hybrid fiber coax (HFC) network using ATM technology. The traffic model is based on the measurements taken on the upstream channels of the network and represents the behavior of the subscribers by simulation.
The proposed traffic model has two characteristics which distinguish it from other traffic models. Firstly, it considers aggregated traffic, so no distinction between types of traffic is needed. Secondly, the parameters of the traffic model are directly related to the network configuration.
