摘要： A security server monitoring device is provided that performs quick redistribution of loads when a server load increases due to virus infections. A security server performs a virus check on data flowing through a network, thus statistical data relating to detected viruses can be obtained. For example, future communication traffic and increases and decreases in server loads are predicted using statistical information such as the number of virus infections (number of virus infections per unit of time), and on the basis of this prediction, a security server allocated to a path is quickly changed from a security server in which a high load is predicted to a security server with a comparably low load.

摘要： A communication network comprised of communication paths of server layers formed hierarchically by communication paths of client layers, wherein the state of control of the communication paths of a layer being controlled is independently managed in terms of both (i) an administrative state and (ii) a subordinate state indicating influence from communication paths of a server layer, the administrative state of the communication paths of the layer being controlled is changed according to the control for setting and releasing the communication paths, and the subordinate state of the communication paths of a client layer influenced by the change of the administrative state of the communication paths is changed accordingly. At this time, when a subordinate state has already been influenced by a state of control of the communication paths of a server layer, the processing for management is terminated.
