Research of denial of service attack defense based on virtual circuit
基于虚电路的拒绝服务攻击防御研究*

This paper designed a denial of service protection base architecture based on virtual circuit. And presented resource allocation algorithm based on virtual circuit. Realized the resource allocation algorithm in the prototype system of the virtual circuit architecture based on service unit network architecture. Compared with other algorithms, the algorithm can effectively fight the denial of service attacks from malicious authorized entities in the networks.
