Network Access Control Strategy Based on Network Calculus in the Main Distribution Network Integration Environment

In the main distribution network integration environment, in order to ensure the service quality of the power service and improve the concurrent processing capability of the network, this paper first proposes the network access model. The model uses the traffic shaping module and the network domain module to enable the network to have admission control capabilities for aggregated flows. Secondly, based on network calculus the paper analyses the traffic characterization model of the service flow and network performance boundary elements, which are key factors for QoS control mechanism, and then an access control algorithm based on network calculus is proposed. Experiment shows the network service access control algorithm proposed in this paper can improve the utilization of network resources.
