An Internet Protocol (IP) multimedia subsystem for use in a telecommunication network. The IP multimedia subsystem comprises: 1) an IP switch for receiving Common Open Policy Service (COPS) protocol messages from an external IP network; and 2) a plurality of call application nodes capable of executing a plurality of Policy Decision Function (PDF) application groups. The IP switch distributes the COPS messages to the plurality of call application nodes according to a load-sharing algorithm.

When a trouble is developed in an IP exchange (TM) 2 or a circuit (network) 5, a backup exchange 6 (backup TM) is switched over from a waiting system to an operating system, and all IP terminals Eqi inside lodgments A, B, . . . N also log out from the IP exchange (TM) 2, and transmit the IP addresses to the backup exchanges 6 (backup TM) inside own lodgment, respectively, and log in there with a result that the extension telephone calls inside own lodgment is made possible by a control of the backup exchange 6 (backup TM), and therefore, even when a fault occurs in the IP exchange or the circuit, the IP terminals inside the lodgment are backed up and the actuations of the IP terminals are continuously operated, and for example, the extension phone calls inside the lodgment can be realized.

The invention discloses a method and a device for transmitting time division multiplexing service through an IP exchange network. The method comprises bearing TDM signals by using an IP pack, packaging the TDM signals into an IP net charge in a TDMoIP frame format, and transmitting to a packet switching network; and receiving the TDMoIP frame from the packet switching network, and carrying out corresponding service after extracting the TDM signals from the TDMoIP frame. The device comprises a TDMoIP frame organizing module, a transmitting module, a forwarding table searching module, a MAC / GMAC device, a receiving module, and a TDMoIP frame decomposing module, and may also comprises a TDM small switching module, a multiplexing module and a demultiplexing module. The invention achieves TDM signal package by using the IP pack so as to achieve more convenient and fast network capacity expansion, and the time gap interleaving multiplexing technique can improve the length of net charges of the TDMoIP frame so as to reduce the cost of pack-front catchword, MAC head and IP head of the Ethernet accordingly and improve the utilization rate of the network bandwidth.

The invention discloses a broadband satellite communication system and a communication method based on satellite-borne IP exchange, including a broadband communication satellite with a satellite-borne IP exchange function, a system network management and control center, a gateway station and a satellite terminal; The broadband communication satellite with IP switching function performs IP switching on the star; the system network management control center cooperates with the gateway station and the satellite terminal to realize the maintenance and distribution of routing switching information based on the satellite-borne IP switching broadband satellite communication system; the satellite terminal According to the switching label information assigned by the system network management and control center, the gateway station will package and unpack the received service data packets to realize the sending and receiving of services. The system performs IP exchange on the satellite without implementing complex routing algorithms. The system construction and expansion are simple and flexible. While improving the utilization efficiency of satellite system link resources, it has good realizability. Simultaneously, the invention also discloses a communication method of the star-borne IP switching broadband satellite communication system.

Enhanced interoperability (e.g., connectivity, communication, processing, routing, billing, etc.) capabilities are provided through an IP eXchange (IPX) facility that among other things may offer a simple, consolidated, etc. interface mechanism and which may leverage various pools of data to expeditiously process and route a quanta of data (including conventional SMS, MMS, etc. messaging; VoIP and other audio / video data streams; SIP-addressed artifacts; signaling data; voice call data; application data; etc.).

A method for measuring a quality of an IP network of a member of a trading exchange includes finding a penultimate hop corresponding to each IP network IP network prefix in a set of IP network IP network prefixes of a member, determining a quality score for the each IP network IP network prefix based on tests performed at the penultimate hop, and creating a matrix for the member including the determined quality for the each IP network IP network prefix. The quality is used to facilitate matching the offers of the buyers and sellers.

The invention discloses a core storage exchange platform system for mass storage system which comprises exchange frame, bridge and a plurality of FC wire-card and iSCSI wire-card, The FC wire-card and iSCSI wire-card are connected through bridge and exchange frame; wherein, the exchange frame is for storage partition and storage exchange, the bridge is for realizing exchanging frame and stream managing of protocol bridge between the FC wire-card and the iSCSI wire-card. The invention can realize storage exchanges between FC and FC, FC and iSCSI, iSCSI and merge FC-SAN and IP-SAN with high efficiency, improve the exchange performance of SAN and realize the function of VSAN. The inventive core storage exchange platform can connect with present disk array, iSCSI, magnetic tape and other storage device, and IP exchange, FC exchange storage devices to construct a large-scale network storage system of great performance and easy extension.

This invention relates to a method for utilizing IP protocol to set up LAN, in which, Ethernet protocol is eliminated in the network adapter to reduce the process time to network data of the host and realize a third layer switch to let the IP exchange have the route function, which applies the following technology: a LAN includes an IP network adapter, an IP exchange and a network access device, in which, the transmitted data in the network are pue IP data packets and the working way of the network is of packet exchange not the traditional packet broadcast of the LAN.
