Two-layer or multilayer networks can more accurately reveal the transmission dynamics of the actual network and increase the traffic capacity. Therefore, we considered optimising the physical layer topology of the two-layer network, and proposed a link deletion strategy at the physical layer. The nodes with maximum weight (\(k_i\)*\(k_j\)) were deleted, where \(k_i\) and \(k_j\) are the degrees of nodes i and j, respectively, and the traffic load was redistributed from the central node to the non-central nodes. The simulation results showed that the strategy significantly increased the network traffic capacity. In two-layer network model, the logical layer network structure is unchanged and the shortest path routing strategy is used.

两层或多层网络可以更准确地揭示实际网络的传输动态，并增加通信量。因此，我们考虑优化两层网络的物理层拓扑，并提出了物理层的链路删除策略。具有最大权重（\（k_i \） * \（k_j \））的节点被删除，其中\（k_i \）和\（k_j \）是节点i和j的度数，流量负载从中央节点重新分配到非中央节点。仿真结果表明，该策略显着提高了网络流量。在两层网络模型中，逻辑层网络结构不变，并且使用了最短路径路由策略。
