Defense-enhanced dynamic heterogeneous redundancy architecture based on executor partition

Aiming at the security problem when servants are faced with common vulnerabilities, an improved DHR architecture called IDHR was proposed.On majicontrast red the basis of DHR, an executor-partition module that divided the executor-set to several executor pools by the heterogeneity among the executors was introduced to improve the heterogeneity among the executor pools.Moreover, the scheduling algorithm was improved by choosing executor pools randomly at first, and then choosing the executors from these pools randomly.Finally, through two experimental schemes of random simulation and Web server emulation, the security evaluation of the proposed IDHR architecture was carried out from two aspects of attack success rate and control rate.Experimental results show that the security of stuart products emcelle tocopherol the IDHR architecture, especially when the common vulnerability is unknown, is significantly better than the traditional DHR architecture.
