  • Patent number: 9191890
    Abstract: IEEE 802.11 power saving mode (PSM) defines two different power modes under which stations operate: active mode and power save (PS) mode. This disclosure introduces devices, methods, and systems to implement an additional power save with ultra low power (PS-ULP) mode that further reduces power consumption. In one aspect, a method of communicating a power management mode of a station on a wireless network is disclosed. The method includes transmitting by a station a first message on the wireless network, the first message indicating one of at least three power management modes, wherein the indication is communicated in a power management portion of a frame control field of a media access control header. The power management portion comprises more than one bit; and operating the station in a power management state in accordance with the indicated power management mode.

  • Patent number: 9178681
    Abstract: A method is provided for sending at least a first data signal and a second data signal, the data being divided into data blocks of fixed size including a header field of predetermined size, the data signals being sent to at least one data processing device adapted to apply a cyclic autocorrelation function with parameter k enabling the first and second data signals to be identified. The value of the parameter k is a function of a ratio between the size of the data blocks and the predetermined size of the header field. The method includes modifying the size of the header field of the data blocks before sending the first data signal, the value of the parameter k and the size of the data blocks remaining unchanged. A method is also provided for processing signals sent in accordance with the sending method.

  • Patent number: 9166758
    Abstract: A user equipment (UE) transmits uplink control information (UCI) of 3 bits or more to a base station (BS) after modulating the UCI into 1-bit or 2-bit sub-UCI units. Here, the UE maps each 1-bit or 2-bit sub-UCI unit to one of a plurality of corner constellation points regardless of modulation order of data which is multiplexed with the UCI. The corner constellation points are points having a maximum Euclidean distance from among a plurality of constellation points corresponding to the modulation order.

  • Patent number: 9130774
    Abstract: Data mirroring in a service such as a virtual private LAN service is disclosed. Data packets, segments, frames, or other forms of encapsulation may be mirrored off of a core network (e.g., IP, TCP) to one or more mirroring destinations without using a parallel network. Encapsulation techniques are provided that enable packets to be mirrored and transmitted across services such as VPLS, MPLS, and others to a mirror destination. Once received at the mirror destination, mirrored packets may be used for troubleshooting in a more efficient and less resource and time-consuming manner.

  • Patent number: 9130870
    Abstract: A network may include switches that have controller clients that are controlled from one or more controller servers. Clusters of the switches that have the controller clients may be isolated from other clusters by switches without the controller clients. The controller server may use graph searches to identify the clusters. The controller server may use information on the cluster topology of switches containing controller clients along with information in per-switch forwarding databases to generate per-cluster forwarding databases. The controller server may use the per-cluster forwarding databases in generating flow tables for the network switches that direct the switches to forward packets along desired paths through the network.

  • Patent number: 9118585
    Abstract: In an optical transport network a traffic flow comprises data grouped into a number of resizable data units, encapsulated by optical transport frames, each having a frame overhead. A rate of the traffic flow is changed by changing the data unit overhead and changing at the source node the frame overhead to indicate a change in rate of an optical signal carrying the traffic flow. An optical transmission part is tuned to transmit at the new rate, and at any intermediate nodes along the route the indication of the change in rate is detected in the frame overhead so that the traffic flow on a next optical link is transmitted at the new rate. Thus optical bandwidth allowed for enlarging the data units, can be saved, and electrical processing of data units at the nodes can be simplified, reducing power consumption.

  • Patent number: 9055551
    Abstract: The present disclosure relates to the mobile communication field and discloses a prefix allocation method, a network system, and a Local Mobility Anchor (LMA). With the prefix allocation method, the network system and the LMA provided in the present disclosure, the problem that a shared prefix cannot be allocated to a multi-interface (IF) Mobile Node (MN) is solved. The prefix allocation method includes: receiving a registration request for a second IF of the MN from a Mobile Access Gateway (MAG); obtaining a first Home Network Prefix (HNP) that is already allocated to a first interface (IF) of the MN; and allocating the first HNP shared with the first IF to the second IF. The LMA obtains the first HNP that is already allocated to the first IF and allocates the first HNP to the second IF. In this way, a shared prefix is allocated to the multi-IF enabled MN.

  • Patent number: 9007888
    Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

  • Patent number: 8934332
    Abstract: A system is disclosed for concurrently processing order sensitive data packets. A first data packet from a plurality of sequentially ordered data packets is directed to a first offload engine. A second data packet from the plurality of sequentially ordered data packets is directed to a second offload engine, wherein the second data packet is sequentially subsequent to the first data packet. The second offload engine receives information from the first offload engine, wherein the information reflects that the first offload engine is processing the first data packet. Based on the information received at the second offload engine, the second offload engine processes the second data packet so that critical events in the processing of the first data packet by the first offload engine occur prior to critical events in the processing of the second data packet by the second offload engine.

  • Patent number: 8902743
    Abstract: A method of enabling an electronic privately addressable source to be publicly addressable starts at a receiver where an electronic message is received. It is communicated from a sender with a private address outside a subnet of the receiver through a translator. The translator retrieves a lease to at least one of a public address or a port from a lease manager, translates the private address and the private port into a public address and a public port and communicates identifying data such as the public address and the public port to the receiver. If a response is communicated to the private sender, the response may be communicated to the private sender through the network. The public address and the public port on the message may be translated to the private address and the port of the private sender and the private address and the private port may be used to properly route the response to the private sender.

  • Patent number: 8817683
    Abstract: In a network relay router 10, a multicast routing protocol processing module 11A sequentially sends a join request message (CP1) to a router 30a functioning as a rendezvous point via an interface 101, based on the settings of a multicast group address or destination address and a sender VRF name. The network relay router 10 receives a multicast packet (DP1) from the router 30a via the interface 101 and acquires a sender address or source address of a transmission device SE from the received multicast packet. The network relay router 10 sends a join request message (CP2) via an interface 102 on the side of the transmission device SE and receives a multicast packet via the interface 102. This establishes an optimum multicast route (MR) between the transmission device SE and the network relay router 10.
