This letter studies the NBA (National Basketball Association)‐traffic offload mechanism based on in‐network caching and D2D (Device‐to‐Device) communication mode, where the router is enabled with the caching ability and the information exchange is based on the direct communication between two D2D groups. Meanwhile, the DPDK (Data Plane Development Kit) is used to do segmentation for the NBA‐video, which can guarantee that all segments have the same size in order to improve the caching efficiency; the clustering analysis based on maximal tree is adopted to divided into some users into several different D2D groups. Furthermore, for each D2D group, the forwarding ability is quantified based on degree centrality and available bandwidth, and it is used to select the group head. The experimental results show that the proposed novel NBA‐traffic offloading mechanism is feasible and efficient.
