  • Patent number: 8824333
    Abstract: An industrial network with bidirectional communication for real time control includes nodes selectively operable in either a switch mode or a serial shifting mode. Nodes operating in the switch mode are capable of initiating data frames for transmission on the network and receiving data frames from the network. Nodes operating in either the switch mode or the serial shifting mode are capable of extracting and/or inserting data into a data frame as it is transmitted through that node. An initialization procedure determines end nodes and intermediate nodes within the network. The end nodes are configured to initially operate in the switch mode and the intermediate nodes are configured to initially operate in the serial shifting mode. The intermediate nodes are additionally operable to selectively toggle between operation in switch mode and serial shift mode and may operate in both modes during a single I/O scan cycle.

  • Patent number: 8774162
    Abstract: Provided is an on-vehicle network which can improve the network use efficiency and reduce the controller processor overhead even when the same communication cycle as the frame cannot be set in the filtering condition of a communication control device. A reference signal transmission controller is arranged in a network so as to generate and transmit a reference signal in accordance with the communication cycle. A reference signal reception controller receives the reference signal and compares the reference signals to a predetermined filtering condition table. If the signal is matched with the table, the controller executes a data reception process and a data transmission process.

  • Patent number: 8774076
    Abstract: In one embodiment, a first Edge Device may join a multicast group via a multicast router, wherein the first Edge device is in a first site of a network and the multicast router is in a second site of the network. The first Edge Device may ascertain an existence of both a first multicast source in the first site of the network and a second multicast source in the second site of the network. The first Edge Device may select the first multicast source as a multicast source from which to receive multicast data for the multicast group. The first Edge Device may notify the second multicast source in the second site of the network that the first Edge Device is not interested in receiving multicast data for the multicast group from the second multicast source.

  • Patent number: 8767618
    Abstract: Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

  • Patent number: 8755383
    Abstract: Techniques herein include systems and methods that extend functionality of transport networks including Transparent Interconnect of Lots of Links (TRILL) networks. Techniques include using a portion of information within transport device address encapsulation headers for purposes other than identifying source and destination device addresses. The system masks a portion of bits in an address header for an address lookup in forwarding tables of a transport network node. The remaining bits in the address field(s) become free bits that can be used for a variety of application purposes, such as flow identifier selection. By using information fields that already exist in encapsulation headers, such techniques provide additional information without increasing packet size or requiring new protocols. Embodiments can combine Equal-cost multi-path routing (ECMP) functionality, Reverse Path Forwarding (RPF) checks, and Time to live (TTL) protection at the same time.

  • Patent number: 8730956
    Abstract: A method and apparatus that operates two bridging protocols in a hybrid bridging node is described. The operation of the two bridging protocols in the hybrid node allows for an incremental transition of a provider bridging network from operating a legacy bridging protocol that shares MAC addresses to a bridging network that operates VPLS and/or PBB bridging protocols. The hybrid bridging node selectively broadcasts unicast packets with unknown MAC addresses from the nodes operating VPLS and/or PBB to nodes operating a legacy bridging protocol.

  • Patent number: 8711854
    Abstract: An upstream error controller monitors a media stream at a location upstream from an associated set of receivers receiving the media stream. The upstream error controller sends out suppression notices for any media packets lost upstream causing the receivers to suppress sending lost packet notices. In another embodiment, a repair point joins a primary multicast group with multiple receivers for receiving a native media stream. The repair point also joins a second multicast group receiving multicast backup data for retransmitting or repairing the native media stream that does not include an associated set of receivers. In yet another embodiment, the upstream error controller is used in combination with a hybrid packet repair scheme for adaptively switching among unicast retransmission, multicast retransmission, and Forward Error Correction (FEC).

  • Patent number: 8705552
    Abstract: An apparatus including a packet ingress interface, a packet egress interface, an eligible egress time module, and an egress module. The packet ingress interface ingresses packets of data into the apparatus. The packet egress interface egresses the packets from the apparatus. The eligible egress time module determines a respective eligible egress time for each of the packets based on a respective ingress time of the packet at the packet ingress interface and a hold interval. The egress module prevents each packet from egressing the packet egress interface until occurrence of the respective eligible egress time.

  • Patent number: 8705504
    Abstract: A method and apparatus, such as a pico service gateway, for reducing backhaul traffic in a broadband wireless access system are provided. The pico service gateway operatively receives an uplink packet including a contents request from a Mobile Station (MS). Upon receipt of the contents request, the pico service gateway determines whether the requested contents have been cached. If the pico service gateway determines that the contents have not been cached therein, the pico service gateway communicates with a corresponding server to receive the requested contents. Thereafter, the pico service gateway transmits the contents to the MS. Further, if the pico service gateway determines that the contents have not been cached, the pico service gateway caches the contents. In contrast, if the pico service gateway determines that the contents are cached therein, the pico service gateway transmits the contents corresponding to the requested contents.

  • Patent number: 8654759
    Abstract: The present invention provides a solution to maximize the chance of completion for an ISUP to SIP direction call by enabling a bigger factor for converting ISUP hop counter to SIP Max-Forwards value than the reverse direction thus enabling more hops in the SIP network. Enabling a bigger factor for ISUP to SIP direction can cause loops without special considerations. This invention provides an algorithm that prevents a “loop condition” that can arise at the interface boundary of two telephone networks, known by their standard names ISUP and SIP networks. The present invention solves the “loop condition” problem by adjusting the Hop Counter and Max-Forward parameter values in a predetermined manner such that the adjusted parameter values break the cycle of providing the same parameter values between networks at the network boundary for an uncompleted connection, or break an endless “loop condition”.
