摘要： Disclosed is a communication network management system for converting action parameters contained in abstract requirements (abstract policy information) regarding a network to parameters conforming to the network technology (ATM, SDH, WDM, etc.) and type of network element to be set, and setting these parameters in the element. Specifically, a policy administration portion converts action parameters contained in abstract policy information to parameters dependent upon network technology and a policy enforcement portion converts the parameters obtained by this conversion to parameters dependent upon type of network element to be set and sets these parameters in the element.

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.

摘要： A packet directional path identifier transfer system contains on the transmission side thereof, a means 2 of converting packet directional path identifier data into bit map information in which an address of each bit corresponds to a packet directional path identifier. The system contains on the reception side thereof, a means 5 for inversely converting the bit map information of the packet directional path identifier data to the packet directional path identifier data. Otherwise, the system further contains on the transmission side thereof, means 8 and 10 for determining the top and bottom values of the packet directional path identifier data to be transmitted, and a means 9 for converting the packet directional path identifier data between the top and bottom values into bit map information, and at the reception side thereof, a means 13 for inversely converting into the initial packet directional path identifier data the bit map information of the packet directional path identifier between the top and bottom values. Further, the top value of the identifier(s) of the newly-set packet directional path(s) determined from the non-used packet directional path identifier(s) in the outgoing packet directional path of the transmission-side node and the number of the newly-set packet directional path identifier(s) are transmitted, and a reference is made to the incoming packet directional path identifier table at the reception-side node to recognize the newly-set packet directional path(s) based on the information received.
