Text semantic key words conceptual decision tree model is constructed for massive English teaching resources allocation, semantic information conversion method is used to compute key semantic features of English Teaching resources, the concept convergence point of English Teaching resource allocation is formed in semantic model. According to the set between the upper and lower relationship, a decision tree model of English Teaching semantic subject words is constructed, semantic conversion and information extraction are realized. English teaching resources optimization allocation simulation is taken in the cloud platform, simulation results show that the scheduling performance of English teaching resources is better, and the adaptive allocation ability of English teaching resources is stronger, and the resource utilization rate is higher.展开更多

This paper focuses on the overall architecture of cloud platform as well as the design of virtualization security architecture. Meantime, it introduces the key technologies of VXLAN in detail. The scheme realizes flexible scheduling of security resources through virtual pooling of independent security gateway and virtual machine isolation through VXLAN technology. Moreover, it guides all horizontal traffic to independent security gateway for processing, unified management of security gateway through cloud platform by using Huawei NSH business chain technology. This scheme effectively solves the horizontal transmission of security threat among virtual machines, and realizes the fine security control and protection for the campus data center.展开更多
