A plurality of virtual client processes for accessing a server are simultaneously operated on test execution terminal, when accessing the server by each virtual client process, respectively unique virtual network addresses are set, a source network address in a transmission packet is rewritten into the set virtual network address from an actual network address, a destination network address in a reception packet from the server is rewritten into the actual network address from the virtual network address, and this packet is transferred to the client with this virtual network address set therein. Load tests of accesses to the server from a multiplicity of client terminals can be executed by a small number of test terminals without depending on network protocols.

Load text execution apparatus, load test execution system, method thereof and program thereof

A terminal apparatus is capable of efficiently managing the status of shared device(s) on the network in a unified manner, constantly, with the latest status information, thereby permitting a user easily to understand the status of the desired shared device. For each of the terminal apparatuses on the network, there are provided server and client. These function in the same manner regardless of whether the information exchange is with another apparatus or within one apparatus. The server means acquires and provides the information of the shared device, required from the client of another apparatus or the same apparatus.

Information management method in network system

By comprising a unit for designating a distribution destination on a network, unit for specifying data to be distributed to the designated distribution destination, unit for determining a distribution method for distributing the specified data, and unit for distributing the data to the designated distribution destination based on the determination, data is appropriately distributed by selecting a distribution method which is suitable to the amount of data to be distributed and the setting state of the network of the distribution destination.

Data processing apparatus and data processing method

System for sharing image input device on network

Environments of various devices such as an image input device are effectively used as a commonly used resource (shared resource) on a network can be simply set without any loss. In an information processing apparatus provided on a network, a CPU checks as to whether or not a device is locally connected to this information processing apparatus, and then notifies this check result to a management device provided on the network. This management device judges as to whether or not a server program of a common system is installed in a terminal apparatus based on a content of a notification issued from this terminal apparatus. In accordance with this judgement result, the management device installs this server program to this terminal apparatus. Furthermore, in an information processing apparatus having a client function with respect to the server program, when this server program is present on the same node on the network, the information processing apparatus is automatically controlled so as to directly communicate, whereas so as to communicate via a network when this server program is present on another node.
