A SURVIVABILITY ENHANCEMENT FOR COMPUTER CLUSTER SYSTEM UNDER DOS ATTACKS

摘要

The present invention relates to a method in a cluster system increase survivability under Denial of Service (DoS) attacks. ; The present invention to achieve this, a denial of service (DoS) healthy stage 20 to the Markov model semi that led to the state transition from the symptoms based determination engine to ensure a level that can maintain availability under attack, recovery stage 30, failure the separation of the stage 40; The condition-based determination engine and health condition to combat them internally in accordance with the user's policy (H), infection (I), rehabilitation state (Rj), the state change to the reconstructed state (Rc) and the failed state (F) is that one should be performed in their characteristics. ; Denial of service attacks, DoS (Denial of Service), cluster system, survivability, healthy stage, recovery stage, stage fails, the cluster system recovery
