摘要： The present invention relates to a method, a system and a device for implementing interconnection between IP domains. The method mainly includes: first, the Media Gateway Controller (MGC) sends the IP domain information of the IP domain to which the media stream to be created pertains to the Media Gateway (MG) between IP domains; when the MG receives the IP domain information for creating the media stream from the MGC, the MG creates the corresponding media stream between the IP domains according to the IP domain information, thus implementing the interconnection between the IP domains. Therefore, the implementation of the present invention enables the MG between the IP domains in NGN, between which interconnecting is needed, to obtain the IP domain information of the IP domain to which the media stream to be created by the MG pertains, thus ensuring the interconnection between the IP domains which need to interconnect with each other, and providing great convenience for network operation.

摘要： A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.

摘要： A method, apparatus, and system are described for accessing networked devices without accessible network addresses via Virtual IP (VIP) addresses. The system consists of a first Device Services Controller (DSC), featuring a Host Controller component that can make available a virtual network interface and corresponding virtual IP address (VIP) and having a first conduit manager to create a first outgoing TCP/IP conduit connection to a device service manager (DSM). When networking traffic arrives at the virtual networking interface with the associated VIP, the Host Controller component automatically processes and forwards that traffic to the DSM. The DSM processes and relays traffic from the first outgoing TCP/IP conduitconnection to a second DSC, which has a Device Controller component and a second conduit manager to create a second direct outgoing TCP/IP conduit connection to the DSM. An IP redirector in the DSM receives communication traffic from the first established TCP/IP conduit connection from the first DSC and then routes the communication traffic down the second established TCP/IP conduit connection to the second DSC based on a Virtual IP address to real IP address mapping stored in the registry of the DSM. The Host Controller component processes and delivers the network traffic from the DSM to the appropriate local networked device and if appropriate send back any return traffic back to the DSM, which will return it to the first DSC for delivery to the originating network device, Using this mechanism, it is possible for two networked devices on separate networks to communicate even if there does not exist a route to the network address of the target device.

摘要： A base station forms a communication area enabling communication with a mobile communication network through a local network that includes the base station. The base station includes a monitoring unit that monitors an address for data communication with the mobile communication network and assigned to a mobile terminal in the communication area; a storage unit that stores combination information indicating a combination of the address monitored and identification information of the mobile terminal; a receiving unit that receives, from a communication terminal in the local network, data having the identification information; a comparing unit that compares the combination information with a combination of a destination address of the data and the identification information in the data; and a transmitting unit that transmits the data to the mobile terminal if the combination and the combination information coincide, and performs error processing if the combination and the combination information do not coincide.

摘要： The invention relates to the technical field of data transmission in a network of distributed stations (11 to 14) . One problem particularly with a UPnP-based home network is that although the network-internal communication is based on the IP protocol, the allocated IP addresses are valid only locally and they therefore cannot be accessed via the Internet . This is the starting point of the invention, which proposes that remote access to the network have the network's switching node (10) provide address conversion which is effected using an internally managed table about the devices which are present in the network and their IP addresses. For the remote access, the globally valid IP address of the switching node (10) is used, with an additional information item being additionally provided in the HTTP Get remote access and allowing the address conversion. A suitable additional information item is the converted local IP address of the network station which is to be addressed, in particular. The response to the remote access involves the inverse address conversion, so that the references back to the local area network again contain the globally valid address of the switching node (10) plus the additional information item.

摘要： A wireless network assigns a single IP address to the wireless device, which assigns this IP address over to a TE2 device coupled to the wireless device. The wireless device derives a private IP address for communication with the TE2 device. The wireless device forwards packets exchanged between the TE2 device and the wireless network using the single IP address. The wireless device exchanges packets with the TE2 device by (1) using the private IP address for outbound packets sent to the TE2 device and (2) performing either address-based routing or packet filtering on inbound packets received from the TE2 device. The wireless device exchanges packets with the wireless network by (1) using the single IP address for outbound packets sent to the wireless network and (2) performing packet filtering on inbound packets received from the wireless network.

摘要： A method of operating a Session Controller is provided. The Session Controller communicates with a client (40) and comprises a signalling proxy (10) and a media proxy (20) , the Session Controller being latched to a media plane address and port. The method comprises: detecting, at the signalling proxy, that the client is changing or has changed its IP address and/or port to a different address and/or port; instructing the media proxy to monitor for incoming media from the client of an address and/or port different from the address and/or port that the media proxy has been using previously as the address and/or port of the client; and if any media is received by the media proxy of such a different address and/or port, using said different address and/ or port as destination address and/or port for media from the media proxy to the client. A corresponding Session Controller, and a signalling proxy and a media proxy for use in such a Session Controller are also disclosed.
