Abstract: When an IP terminal on the Internet side transmits a name resolution request, which requests to resolve the FQDN of a public server connected to a router, to a SIP/DNS server in which SIP and DNS cooperate to manage the status of the data line of the router and when the data communication line status of the router is a disconnect status, a data communication line connection request instruction is transmitted to the router. The router connects the data communication line and notifies the SIP/DNS server about the result. The SIP/DNS server transmits the IP address of the router to the IP terminal as a response.

Abstract: In a packet forwarding apparatus including first line interfaces accommodating user terminals, a second line interface connected to a communication node on a session management apparatus side, and a protocol processing unit for updating a connection management table and a header information table when a specific session control packet is received from one of the first line interfaces. Upon receiving a real-time packet from one of the first line interfaces, if a table entry corresponding to the header information of the received packet has been registered in the connection management table, the control unit routes the received packet to one of the first line interfaces after rewriting its header information based on the header information table, and if the table entry has not been registered, the control unit routes the received packet as it is to the second line interface.

Abstract: In a network having an L2SW in which uplink VLAN is set, a transfer delay of a voice call packet is prevented. In a process of establishing a session between terminals (5), a packet transfer device (1) stores information capable of specifying a sending terminal (5-1) and a receiving terminal (5-2) and a correspondence relation (user connection information) to a connection port into a table. A SIP message of a session control packet communicated between the terminals (5) is snooped, and a destination IP address, a transmission source IP address, a destination port number, a transmission source port number, a connection port etc. are stored into the table. In a case where an RTP packet as voice data is received after the session is established, the packet transfer device (1) performs a loopback transfer or transfers it to an uplink port in accordance with the table.

Abstract: UV-resistant materials are disclosed that include at least one self-supporting film of UV-resistant clay particles and that are substantially non-reactive to incident UV radiation. An exemplary material is substantially non-transmissive to at least one UV wavelength of less than 300 nm, can include a polymeric material for enhanced flexibility, and can include an additive that is non-transmissive to at least one UV wavelength of greater than 300 nm. The material can be multiple layers of respective clay films. The materials can be used to form UV-resistant devices such as seals, mounting cushions, and light-shields for use in any of various UV-illumination sources and process systems. An example UV-illumination source is an excimer laser. An example system is a light-CVD system.

Abstract: The migration of telephone services by a telecommunications carrier from a PSTN to an IP network entails that problem that when it is not possible for some telephone subscribers to migrate to the IP network due to the types of their telephone lines or services they subscribe to, other subscribers also cannot migrate to the IP network until the former subscribers migrate to the IP network. The present invention provides a media gateway that enables a gradual transition from a PSTN to an IP network on a subscriber-by-subscriber basis or on a service-by-service basis so that a telecommunications carrier can efficiently migrate its subscribers while continuing to provide the services the subscribers currently use and reducing burdens on the subscribers.
