Abstract: A SOAP-SIP adapter 2 establishes a session with the terminals 5b and 5c in accordance with a SIP. At this time, the SOAP-SIP adapter 2 sends an INVITE message including its own IP address and port number to the terminals 5b and 5c. Each terminal 5b, 5c sends a 200 OK including its own IP address and port number to the SOAP-SIP adapter 2. The SOAP-SIP adapter 2 stores correspondingly the IP address and port number of each terminal 5b, 5c in a memory. The SOAP-SIP adapter 2 transfers a media stream received from each terminal 5b, 5c to the destination of the corresponding IP address and port number by referring to the memory. Also, a pseudo RBT is sent to the terminal A5b from establishing the session with the terminal A5b till establishing the session with the terminal B5c to prevent a silent state.

Abstract: Disclosed here is a method for producing an antifouling paint composition using metal-containing polymer particles, an organic solvent and acrylic polymer (P) that is soluble in the organic solvent. According to the method, an antifouling paint composition is obtained, which is useful for producing a high-solid antifouling paint having excellent storage stability along with a shorter drying time because of capillary action among the polymer particles.

Abstract: A network system, management server, and OAM test management method for grouping the virtual networks, selecting a test target for each group, and lowering the network load and the operating load in the OAM testing. Grouping the multiple virtual networks based on their physical topology and selecting a representative virtual network for each group, allows selecting a test target virtual network from among the representative virtual networks for the virtual network selected by the operator and executing tests.

Abstract: A reservation processing is executed according to the configuration request to VPN and network device to inform a user's terminal of scheduled period. In a network system including plural network devices for transmitting a packet and a management server, plural logical networks (VPNs) are formed on the plural network devices. The management server receives a configuration request including configuration data for VPN and configuration desired time from a user's terminal to generate the configuration data for the network device from the configuration data for the VPN. The management server refers to a configuration reservation table to confirm whether free time is available in the same period about all target network devices. If free time is available, the management server makes configuration reservation and configures the target network device in the reserved time. The management server notifies the user's terminal of the reserved time.

Abstract: One of objects is to reduce a load in a session management and relay process on an SOAP-SIP adaptor for providing a 3PCC service. The SOAP-SIP adaptor (hereinafter the adaptor) receives a connection request message between a first terminal and a second terminal from a Web server, and establishes the sessions with each of the first terminal and the second terminal. After establishing the sessions with each of the first terminal and the second terminal, the adaptor sends a transfer request (REFER) of session to a call control device. Thereafter, the call control device manages session between the first terminal and the second terminal each having established the session with the adaptor.
