Abstract: A radar, or other repetitive interference, detection and data flow control system and method for RF data transmissions uses an RF detector and an omni directional antenna to detect radar or similar signals. The information from the RF detector is communicated to a hub data transmission unit which processes the data about the signal provided by the detector. This information is used by the hub to schedule communications between the hub and subscriber units so that none of the communications between the hub and subscriber fall within the time period of the interfering pulses. Although there are no communications during the time periods of the pulses, the efficiency of communications is improved because collisions and retransmission of data are avoided.

Abstract: A system and method for maximization of the global throughput of packet transport networks via traffic-load-adaptive TDM or WDM channelization. Architecturally the packet transport network is formed of logical packet transport buses that are configured in the network for transport of packets to one of the nodes of the network from the other nodes of the network. Each logical packet transport bus is dynamically channelized to create an adaptive full mesh connectivity among the nodes in the network, such that the capacity of each connection in the mesh is continuously optimized according to real-time inbound traffic patterns at the packet transport network, thereby globally optimizing the throughput of the network. The dynamic channelization of each bus is done under the control of its destination node based on the demand for transport capacity towards it presented by the individual nodes in the meshed packet transport network.

Abstract: The creation, modification, and deletion of a traffic stream 224 with parameterized QoS expectations between two communicating stations 205 and 207, when there is no built-in mechanism for support of parameterized QoS expectations, requires signaling of traffic characteristics and QoS parameters between the management entities such as SME 212 and MLME 214 and between the MAC entities of the communicating stations 205 and 207. Either the station 205 and 207 or a hybrid coordinator may initiate the signaling. The end result of the signaling is the creation of a new traffic stream that is used to associate user traffic to a particular set of traffic characteristics and QoS parameters, which are then used in the scheduling of the transmission of the user traffic. Another end result of the signaling is the modification of an existing traffic stream in terms of its traffic characteristics and QoS parameters.

Abstract: A system and method for transmitting a file stream using quality of service capable links. The system has a network capable of supporting quality of service negotiations and an embedded component capable of negotiating different quality of service levels for a plurality of file streams according to importance of bits to be transmitted. To transmit the compressed data, the embedded component identifies important bits and less important bits in the file stream, negotiates quality of service parameters for a plurality of file streams, divides the important bits and less important bits into different file streams having different quality of service levels, and transmits the streams. On the receiving end, the received streams are synchronized and combined into a single stream for the application to display. The error correction and detection coding is performed by physical layers of the network, not the application or embedded component, thereby improving efficiency.

Abstract: Techniques for determination of endpoint Internet Protocol (IP) address assignment in an Internet telephony system are disclosed. In conjunction with the establishment of a voice path between an endpoint and a gatekeeper in the Internet telephony system, a virtual address assigned to the endpoint in a network address translation operation is determined. The virtual address is then communicated to the endpoint as part of or otherwise in conjunction with a registration process prior to establishment of the voice path such that the registration process can complete successfully despite the network address translation operation. Advantageously, the invention overcomes problems associated with voice path registration failures resulting from network address translation in a router, virtual private network (VPN) gateway or other similar network address translation device.

Upon resignation of the first network element as representative in respect of one of the protocol sets, the routing apparatus is arranged to cause the respective routing data packet for that protocol set only to be purged from the network.

Abstract: A desired FIFO buffer fill level is continuously derived during mapping or demapping of plesiosynchronous data signals into synchronized data signals, or vice-versa. One of j predefined integer values Ii is repetitively consecutively produced during each consecutive one of j FIFO buffer write clock cycles, where i=1, . . . , j and where j and the integer values Ii are selected such that ? i = 1 j ? ? I i j closely approximates the number of bits read from the FIFO buffer per FIFO buffer write clock cycle. During each kth consecutive FIFO buffer write clock cycle, a Bits_Read value Ik+Ik-1 is produced where k=1, . . . , p; a Bits_Written value is produced; a Gap_Pattern value is derived by subtracting the Bits_Read value from the Bits_Written value; and, the Gap_Pattern is added to a predefined value representative a FIFO buffer center fill level to produce the desired FIFO buffer fill level.

Abstract: Disclosed are methods and apparatus for providing redundant data forwarding or routing capabilities. In one embodiment, a network device includes a designated router and a non-designated router. The designated router generally provides layer 3 switching or routing for data received into the network device. Although the non-designated router is active, it generally does not provide forwarding capabilities until the designated router fails. The non-designated router's logical interfaces are disabled, while the designated router's logical interfaces are enabled. The non-designated router becomes the new designated router when the first designated router fails. In general terms, the routers of the network device provide redundancy with the network being aware of only a single router within network device. That is, the network is only aware of a single router. This is accomplished by having the routers share the same IP and MAC address on each logical interface.
