动态自适应链路故障检测方法
Novel dynamic adaptive link failure detection method
摘要
Abstract
T he existing failure detection methods can′t satisfy failure detection time limit requirement to high real‐time business .A dynamic adaptive adjustment algorithm of detection interval was pro‐posed .Aiming at the problem of detection time setting of the proposed algorithm ,analytic expression of the expected failure time of the link was ratiocinated .The proposed method takes adjustment of de‐tection interval as an entry point ,and adjusts detection interval continually according to link quality . Moreover ,closed loop feedback detection mechanism was formed .Results show that fast failure de‐tection can be achieved with low false alarms w hen failure detection time is set to fourth time the value of detection interval ,the proposed method can decrease 15% packets spending ,and reduce 60% fail‐ure detection time ,and has visible failure detection advantages in congestion complex networks .关键词
