| The 5G bearer network is the network between core network and base station. Bearer network, as the information transmission channel between wireless access network and core network, shoulders the important task of transmitting various voice and data services. Therefore, the Qos of bearer network link must be guaranteed. In this paper, the available bandwidth (AB) of end-to-end network of 5G bearer network is dynamically detected to check whether the link has enough network resources. Kalman filter is used to track the effective bandwidth. In addition, this paper also introduces two background traffic modeling methods that are closer to the real network environment. The algorithm is implemented on NS3 simulation platform, and the simulation results show that the algorithm has good performance. |
