摘要

PROBLEM TO BE SOLVED: To provide a system capable of swiftly and precisely checking the normality of a service function chaining.SOLUTION: A monitoring system 200 gives an instruction to a dummy point 300 to perform a path investigation, and the monitoring system requests a network function which is included in a chain 900 to transmit an evidence information. The monitoring system checks the normality of the chain based on the path information acquired from the dummy point 300 and the evidence information and the chain information acquired from the chain 900.SELECTED DRAWING: Figure 1
