The Composition and Security Strategy of Semi-Centralized SDN Routing in Data Center Network

In the operation of data center network system, the calculation and distribution of route is mainly operated by the central controller, so it has become the vulnerable point of network system operation. In the development of modern science and technology, in order to effectively solve this problem, scholars put forward the application of semi-centralized routing technology, which requires all switch nodes to be free from router control and be able to form relatively basic Liu tables independently, thus completing data forwarding. In this paper, we learn.
