天地一体化网络中防护负载均衡技术的研究

he space-ground integrated information network is one of major projects in the field of national information technology. Because the space-ground integration information network is more complex than the traditional network, it faces more security threat.And there are great differences in the performance of heterogeneous networks. Therefore, the unbalanced distribution of protection load of each device should be considered when network security protection is carried out. In this paper, we study the problem of protection load balance in the process of network security protection, and propose a method to protect the protection load balance. Experiments show that, this method can effectively evaluate gateway protection load and achieve more efficient network defense. The real-time protection capability of each gateway are considered when generate protection strategies. Therefore, it can avoid the problem that a single security gateway bears too much protection load and guarantee the network resources to the greatest extent.
