  • Patent number: 9929965
    Abstract: Techniques are described for providing traffic-aware sampling rate adjustment within network devices. As inbound packets are received at an interface, a sampling unit of a forwarding circuit of the network device samples the inbound packets at a current sampling rate and directs a subset of the inbound packets to a service card of the network device. A flow controller within the service card of the network device processes the subset of the inbound packets to generate flow records. When changes in the rate at which the inbound packets are received exceed a defined threshold, the flow controller adjusts the current sampling rate at which the forwarding circuit samples the inbound packets received at the interface. Moreover, the flow controller adaptively adjusts the sampling rate such that the flow sampling resources the device are being utilized in accordance with the utilization thresholds.

  • Patent number: 9917785
    Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.

  • Patent number: 9900815
    Abstract: Provided in one aspect is a method for handling a frequency priority performed by a terminal in a wireless communication system. The method comprises: receiving minimum priority application request information from a network; and handling a frequency priority for cell reselection on the basis of the minimum priority application request information and the supporting characteristics of the terminal. The minimum priority application request information indicates an application of the minimum priority to a current frequency of the terminal or all frequencies of current radio access technology (RAT) of a cell which the terminal camps on. The supporting characteristic of the terminal is whether the terminal supports the RAT other than the current RAT. The handling of the frequency priority is a variable application of the frequency priority for the cell reselection according to the contents of the minimum priority application request information and the supporting characteristics of the terminal.

  • Patent number: 9819770
    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for using different MAC addresses in frames for the same station to indicate how to process the frames. In this manner, frames for IEEE 802.11ac can carry information not present in legacy frames (e.g., frames according to IEEE 802.11a/n), but these frames may be interpreted by legacy devices in a legacy way. One example method generally includes receiving a first frame comprising an indication of a first MAC address and processing the received first frame based on the first MAC address. For certain aspects, the method further includes receiving a second frame comprising an indication of a second MAC address, wherein the second MAC address is different than the first address; and processing the received second frame based on the second MAC address, such that the processing of the second frame is different than the processing of the first frame.

  • Patent number: 9800997
    Abstract: A perturbation is made to contents and/or locations in time and frequency of Reference Signals (RS) transmitted by a cell, such that the perturbation implies information regarding a capability or configuration of the cell as regards availability or configuration of a network functionality, for example facility to offer a narrowband virtual carrier operation. The contents and/or locations in time and frequency of the reference signals used are typically based on the physical cell identity (PCI). In certain embodiments the PCI carried by some identifiable RS resources is changed: in others, the RS is transmitted in unexpected resources. The network functionality configuration information is inferred from the various relationships between these transmissions and the cell's actual PCI and/or expected RS transmission resources.

  • Patent number: 9787492
    Abstract: In general, techniques are described for provisioning network devices in an Ethernet-based access network. For example, an access node located in an Ethernet-based access network positioned intermediate to a back office network and a customer network may implement the techniques. The access node comprises a control unit that discovers a demarcation point device that terminates the access network of the service provider network at the customer network. The control unit of the access node implements an Ethernet protocol to provide layer two network connectivity between the service provider network and the customer network, authenticates the demarcation point device based on a unique identifier assigned to the demarcation point device and, after successfully authenticating the demarcation point device, provisions the demarcation point device.
