Patent ID: 8219889

Claim:
A communication error detection apparatus, comprising: a packet receiving part which sequentially receives packet signals from a communication network; a sampling part which sequentially sorts said packet signals received by said packet receiving part and samples accompanying information contained in said sorted packet signals based on a sampling method supplied to said sampling part; an information storage part which accumulates said accompanying information sampled by said sampling part; and an error detection processing part which analyzes said accompanying information accumulated by said information storage part based on a data analysis method corresponding to said sampling method and which performs a detection process for detecting errors that occurred in said communication network; and a trigger part which respectively supplies said sampling method and said data analysis method to said sampling part and said error detection processing part, said trigger part including initial sampling means for supplying an initial sampling method to said sampling part as said sampling method and for supplying an initial data analysis method corresponding to said initial sampling method to said error detection processing part as said data analysis method when said communication error detection apparatus is installed on said communication network, and normal sampling means for supplying a normal sampling method to said sampling part as said sampling method and for supplying a normal data analysis method corresponding to said normal sampling method to said error detection processing part as said data analysis method when an amount of said accompanying information accumulated in said information storage part has reached a predetermined value.
