摘要
为了提高ControlNet的快速性和稳定性,提出了基于带宽优化的网络拥塞避免策略。由于ControlNet是由一些相互关联的节点组成的,可以采用生产者/消费者多节点网络的带宽优化方法来控制单个节点的信息传输,提高了网络利用率。根据生产者/消费者多节点网络的通信机制,总结出一套高效的带宽优化算法,并给出详细的算法步骤。以CPU利用率、平均带宽利用率和峰值带宽利用率作为衡量ControlNet网络性能的重要指标,对所设计的带宽优化算法进行验证,实验结果表明,所提出的带宽优化算法能有效解决ControlNet的网络拥塞问题。
In order to improve the rapidity and stability of ControlNet, congestion avoidance strategy with bandwidth optimization is proposed in this work. Because industrial ControlNet is composed of several interconnected nodes, bandwidth optimization method of producer/consumer multi-node network can be adopted to control information transmission of each node on ControlNet and network utilization can be improved consequently. According to the working principle of producer/consumer multi-node network, a set of efficient bandwidth optimization algorithm is summed up. CPU utilization, the average bandwidth utilization and peak bandwidth utilization are important indicators for evaluating ControlNet performance, the bandwidth optimization algorithm designed in this paper can be verified by these indicators. The experimental result shows that the problem of ControlNet congestion can be well solved by bandwidth optimization.
