DISTRIBUTION CONTROL METHOD, DISTRIBUTION CONTROL DEVICE, AND STORAGE MEDIUM

摘要

A distribution control method executed by a computer configured to manage a plurality of nodes that controls communication between a plurality of communication devices and a plurality of information processing devices, each of the plurality of nodes having a filter rule indicating whether each of the information processing devices is permitted as a communication destination and collectively receiving, from the computer, all filter rules updated by the computer during a stopped state when the each of the plurality of nodes transits from the stopped state to an operating state, the method includes stopping at least one node among the plurality of nodes; operating at least one node among the plurality of nodes and is in the stopped state for a time period exceeding a predetermined threshold; and distributing the updated filter rules to the at least one operating node among the plurality of nodes, when the filter rules are updated.

1. A distribution control method executed by a computer configured to manage a plurality of nodes that controls communication between a plurality of communication devices and a plurality of information processing devices, each of the plurality of nodes having a filter rule indicating whether each of the information processing devices is permitted as a communication destination and collectively receiving, from the computer, all filter rules updated by the computer during a stopped state when the each of the plurality of nodes transits from the stopped state to an operating state, the distribution control method comprising:
stopping at least one node among the plurality of nodes; operating at least one node among the plurality of nodes and is in the stopped state for a time period exceeding a predetermined threshold; and distributing the updated filter rules to the at least one operating node among the plurality of nodes, when the filter rules are updated.
