摘要：
A processor and program for analyzing network trace with the use of data packets transmitted via a network includes: a memory section 32 for storing trace data generated from the data packets; a packet analyzing section 34 for retrieving a pair of packets belonging to the same session from the trace data to generate an order relation between nodes; an array data generating section 36 for using packet pair data and order relation data to generate and store array data used for estimating time difference of the specific time axis of each node; and a solution engine section 38 for calculating an estimated value of the time difference with the use of the array data to store the estimated value in a memory.
