Claim 0:
1. A system determination apparatus comprising:
a calculation unit, implemented using one or more computing devices, configured to calculate (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
a determination unit, implemented using one or more computing devices, configured to determine 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 the determination unit is configured to determine 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,
wherein the determination unit is configured to determine 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.
