Packet Adaptive Failure Detection Algorithm Under Network Access Control
This paper proposes a packet-based Adaptive Failure detection algorithm,namely,packet adaptive failure dectector(PAFD).The algorithm first groups nodes according to network access rights.In the group,a single point detection mechanism with election algorithm is used to ensure the continuity and accuracy of detection,and an adaptive heartbeat al-gorithm is designed to improve the fine granularity of timeout prediction.In order to ensure the continuity and accuracy of detection,a two-stage detection mechanism is designed to detect the access restricted group.The experimental results show that the error rate and detection time of PAFD are reduced by more than 22.62%and 15.51%respectively compared with BasicFD and HS-FD.
