PROBLEM TO BE SOLVED: To change a distribution destination when processing packets by parallel processing by a plurality of processing cores, and to reduce influence of processing delay generated when changing the distribution destination.SOLUTION: In a distribution part 107 for distributing flow to a plurality of processing cores, utilization of two old and new distribution algorithms is made possible. The state of applying the old distribution algorithm and distributing the flow is switched to the state of applying the new distribution algorithm to the flow by temporally changing a threshold for a hash value calculated from the flow so as to increase the probability of applying the new distribution algorithm to the flow with the lapse of time for each flow. |
