Abstract:

An adaptive detection mechanism is presented to detect the label switched path (LSP) failure. Based on the adaptive LSP detection model, the network delay and thedetection timeout are measured with loopback detection. According to the delay and timeout, this mechanism adaptively adjusts the detection period and schedules thetransmission of detection packets. The failure is quickly detected with a few detection packets. Experiments show the mechanism can find failure in required time, and the detection costs are lower than the fixed period detectioncosts. 
