Abstract: A management device includes a storage unit and a processor. The processor is configured to store, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in the storage unit. The processor is configured to generate, when restoration to a first generation is requested by a first client, new configuration information with reference to information stored in the storage unit. The new configuration information does not include first contents of first updates made by the first client in second generations later than the first generation and includes second contents of second updates made in the second generations by second clients. The processor is configured to perform a configuration of a network device using the new configuration information.

Abstract: Disclosed is a traffic distribution device, which is used in a way that connects to a 0-th network, a first network including one or more servers and to a second network connected to the first network and including M-pieces of high-order layer processing devices associated with 0 through M-1, capable of improving a throughput of a network without changing a server sided default gateway address.

Abstract: When converting client character code on a CORBA client in a client-server system that is based on common object request broker architecture, server character code information which a CORBA server as a transmission destination can use is obtained from an object reference. The client character code information is then converted into the server character code information. The server character code information is set to communication data that is transmitted from the CORBA client to the CORBA server. The conversion of client character code information into the server character code information is performed based on a table containing relationship between the server character code information and client character code information that the CORBA client can use and that is not registered in the object reference.
