Claim 4:
5. A system determination method performed by a system determination apparatus, the system determination method comprising:
calculating (i) a variation coefficient representing a degree of variation of traffic and (ii) an average traffic amount corresponding to a plurality of days using traffic data of a network apparatus corresponding to the plurality of days; and
determining a system of the network apparatus using a density of a data group representing a relationship between the variation coefficient and the average traffic amount corresponding to the plurality of days,
wherein determining the system of the network apparatus includes:
determining the system of the network apparatus to be (i) a non-operation system based on the density of the data group being equal to or greater than a first threshold and (ii) an operation system based on the density of the data group being less than the first threshold, and
determining that the system of the network apparatus is opposite of a previously determined system based on (i) the density of the data group being equal to or greater than the first threshold, (ii) the average traffic amount being equal to or greater than a second threshold, and (iii) the variation coefficient being equal to or greater than a third threshold, and

wherein determining that the system of the network apparatus is the opposite of a previously determined system comprises switching the system of the network apparatus from (i) a previously determined non-operation system to an operation system or (ii) a previously determined operation system to a non-operation system.
