Abstract
A system analyzing apparatus obtains a message group including a message ID, a protocol, a type, and a transmission time of messages transmitted/received in a system where a hierarchical structure of protocols is defined. The apparatus detects pairs of a request message and a response message of the same message ID from the obtained message group. The apparatus identifies a request time and a response time of each of the detected pairs. The apparatus searches for a child-layer pair that has a request time and a response time between the request time and the response time of a parent-layer pair arbitrarily selected from among the pairs and that has a protocol in a layer lower than the protocol of the parent-layer pair on the basis of the identified result. The apparatus outputs the found child-layer pair as a candidate pair having a call relationship with the parent-layer pair.
