A test device includes a virtual machine. The device has a virtual bridge which, when receiving a packet transmitted from the virtual machine to a computer connected via a network, transmits the packet to the computer via a physical interface of the test device. The device has a load generating unit for generating a first packet that provides a communication load and transmitting the generated first packet to the virtual bridge. The device has a return unit for receiving the generated first packet from the virtual bridge, not transmitting the generated first packet to the computer, returning the first packet to the second virtual machine by changing a destination address, and terminating the transmission.

A communication apparatus includes an input interface to receive a flow of segmented data, and an output interface to transmit the received data from a plurality of physical links. The output interface includes storage units corresponding to the respective physical links to store transmission data. A link monitor unit observes how much data is accumulated in each storage unit. A distribution unit selects which physical link is to be used to output the received data. Based on the observations by the link monitor unit, the distribution unit changes the selection to an alternative physical link that has a larger amount of stored data than the currently selected physical link.

A data relaying apparatus disposed on the preceding stage of a registry server centrally managing meta-information extracts meta-information from a content retrieval result transmitted from the registry server to a client terminal and retains and correlates the meta-information with URI information included in the meta-information. On the other hand, a data relaying apparatus disposed on the preceding stage of a repository server retaining contents receives a content acquisition request transmitted from the client terminal to the repository server to extract URI information from the content acquisition request and transmits the URI information to the data relaying apparatus to acquire meta-information. The meta-information is added to contents transmitted to the client terminal before the contents are relayed.

A connection assistance apparatus avoids unauthorized access and DoS attacks, prevents a performance degradation from occurring, and does not need to recognize different connections to gateway apparatus. An authenticating unit authenticates the validity of a terminal by checking if the terminal is a valid terminal capable of communicating with a gateway apparatus according to IPSec in response to a request from a user who owns the terminal. If it is judged that the terminal is a valid terminal, then a preshared key generating unit generates a preshared key for the terminal and the gateway apparatus, and a firewall opening instruction information generating unit generates firewall opening instruction information to open a firewall of the gateway apparatus. A transmitting unit sends the preshared key to the terminal and the gateway apparatus and sends the firewall opening instruction information to the gateway apparatus.

An input line interface device that is used to accommodate packets from a high-speed line efficiently and to reduce a processing load on a back stage caused by routing control. A packet allotting section divides a variable-length packet, allots divided packets to parallel lines, and outputs the packets. A flow group classifying section classifies the packets into flow groups on each of the parallel lines. A sequence number giving section gives the packets sequence numbers corresponding to or independent of the flow groups. A buffering section stores the packets to which the sequence numbers have been given in a buffer or reads out them from the buffer to exercise sequence control over the packets in the flow groups. A flow separating switch separates the packets according to the flow groups and outputs the packets.
