Patent number: 9590948Abstract: One embodiment provides a system that facilitates forwarding of packets with variable length names. During operation, the system receives a packet with a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The system performs a longest prefix match lookup by selecting an entry from a first data structure of entries. The entries indicate a name component, forwarding information for the name component, and a plurality of entry identifiers that chain an entry to another entry. If a size of the name component is less than or equal to a predetermined threshold, the system selects an entry based on the name component. If the size is greater, the system selects an entry based on a compressed key which can be a hash of the name component. The system also resolves collisions associated with the selected entry.Type: GrantFiled: December 15, 2014Date of Patent: March 7, 2017Assignee: CISCO SYSTEMS, INC.Inventors: Marc E.

Patent number: 9572084Abstract: A method and system for route optimization during switching and an access network element. In a process that a terminal is switched from a source access network element to a target access network element, the target access network element obtains identity information of a correspondent node of the terminal from the terminal, and triggers an access network element of the correspondent node to update a correspondent node mapping relationship. In the present solution, information of a correspondent node is obtained by adding a signaling interaction procedure between the network and the terminal host, so that the information of the correspondent node which is performing data communication is obtained in real time, and a subsequent data stream route optimization process is performed in time, thereby solving the problem of low processing performance and poor real-time performance resulted from an access gateway monitoring, detecting and maintaining correspondent node information.Type: GrantFiled: November 1, 2012Date of Patent: February 14, 2017Assignee: ZTE CorporationInventors: Qiang Wu, Hua Jiang, Tao Fu

Patent number: 9554347Abstract: A method and system for measuring end-to-end processing delay of the RE between an input interface and a transmit port in the downlink direction and a receive port and an output interface on the uplink direction is disclosed. The method and system if for use in a radio equipment node (RE) connected to a radio equipment control node (REC). Once the downlink and uplink radio channels are activated at a predetermined carrier frequency, a chirp sine wave is added at the input interface and the receive port such that the chirp sine wave becomes mixed with the carrier frequency. Sampling of a received downlink mixed signal is done at the transmit port and of the received uplink mixed signal at the output interface. The sampled mixed signals are then cross-correlated with a reference chirped sine wave to obtain a signal phase shift which is then converted to obtain a time delay associated with the end-to-end processing delay of the RE.Type: GrantFiled: May 14, 2014Date of Patent: January 24, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Robert Griffioen

Patent number: 9538550Abstract: A first cell determines that UE(s) should have HARQ cycle(s) skipped, where each of the UE(s) is to take part in a CoMP transmission. Skipping is to be performed to enable the first cell to receive information from second cell(s) over backhaul link(s) for the HARQ transmission(s). A first HARQ cycle is scheduled and participated in for the UE(s) in order to receive a transmission at the first cell from the UE(s). The HARQ cycle(s) is/are skipped for the UE(s) by sending, prior to decoding information from the uplink CoMP transmissions, an acknowledgement to the UE(s) and not scheduling the UE(s) for a PDCCH grant for the HARQ cycle(s). The skipping depends on one or more of: a backhaul latency, a load in the first cell, a type of UE, or a request to the second cell(s). Apparatus and program products are also disclosed.Type: GrantFiled: October 3, 2014Date of Patent: January 3, 2017Assignee: Nokia Solutions and Networks OyInventors: Deepak Pengoria, Shirish Nagaraj, Rajeev Agrawal

Patent number: 9398485Abstract: A wireless sensor network system includes: sensor terminals and a management terminal. A sensor terminal sends a join request at a first transmission power; and the management terminal calculates the traffic load of nodes on the reception path of the join request. If the number of hops and the traffic load are both within respective permissible ranges, the management terminal sets the reception path as the communication route of the sensor terminal. If the number of hops and/or the load is not within the permissible rage, the management terminal reconstructs the communication path by outputting an instruction to the sensor terminal to make direct connection to the management terminal or a specified node with a low traffic load, at a second transmission power greater than the first transmission power. When receiving the instruction, the sensor terminal transmits to the management terminal or the specified node at the second transmission power.Type: GrantFiled: May 28, 2012Date of Patent: July 19, 2016Assignee: HITACHI KOKUSAI ELECTRIC INC.Inventor: Masayuki Ishizaki

Patent number: 9385971Abstract: In a multi-chassis link-aggregation device, each of first and second switch devices is provided with a relay condition, which defines prohibition of a predetermined relay path. If there is no link failure in each multi-chassis link-aggregation device, each of the first and second switch devices prohibits forwarding of a frame, which has been received by a bridge port, from each multi-chassis link-aggregation device. On the other hand, if a link failure is present in a second port (second multi-chassis link-aggregation device) of the first and second switch devices permits forwarding of the frame, which has been received by the bridge port, from the second port. In this case, if a destination port of the frame received by a first port includes the second multi-chassis link-aggregation device, the first switch device adds a port identifier representing the received port to the frame and forwards that toward the second switch device.Type: GrantFiled: December 23, 2013Date of Patent: July 5, 2016Assignee: Hitachi Metals, Ltd.Inventors: Nozomi Hashimoto, Wataru Kumagai
