Abstract: A network device may include a controller and a hardware forwarding component. The hardware forwarding component may receive a network packets and assign the network packets to multiple network queues. The network device may also obtain, using a microcode engine of the hardware forwarding component, and for each of the network queues, a measurement of queue depth, each measurement of queue depth being obtained from memory of the hardware forwarding component. Based on the measurements of queue depth, the network device may generate and transmit a telemetry packet.

Abstract: In general, techniques are described for dynamically controlling host-bound traffic by dynamically adding and updating, within the forwarding plane of a network device, network packet policers that each constrains, for one or more packet flows, an amount of host-bound traffic of the packet flows permitted to reach the control plane in accordance with available resources. In one example, a control plane of the network device detects internal congestion in the communication path from the forwarding plane to control plane (the “host-bound path”), identifies packet flows utilizing an excessive amount of host-bound path resources, computes limits for the identified packet flows, and adds “penalty-box policers” configured with the computed limits for the identified packet flows to the forwarding plane. The forwarding plane subsequently applies the policers to the identified packet flows to constrain the amount of traffic of the packet flows allowed to reach the control plane to the computed limits.

Abstract: The present disclosure provides a UV film sensor, a preparation method therefor, and a corresponding touch screen. The UV film sensor comprises a film substrate (A) containing a printing surface (a) and an attaching surface (b), and a UV adhesive layer (1), an electroplated color developing particle layer (2), an ink layer (3), a hardened layer (4), an index matching layer (5) and a transparent conducting layer (6) for constructing a touch function structure are sequentially formed on the printing surface of the film substrate from one side close to the film substrate to the other side away from the film substrate. The touch screen is obtained after adhering a cover glass to the attaching surface of the film substrate in the UV film sensor via an optical grade transparent double-sided adhesive. The obtained touch screen only contains one layer of substrate. The touch screen can be thinner as a whole.

Abstract: A device may determine a first aggregation level for aggregating incoming packets. The device may aggregate the incoming packets using the first aggregation level. The device may determine that a controlled packet pass rate for the incoming packets satisfies an arrival rate threshold based on aggregating the incoming packets using the first aggregation level. The device may determine a bandwidth violation trend associated with the incoming packets and the first aggregation level based on determining that the controlled packet pass rate satisfies the threshold. The device may determine that flow suppression is not effective at the first aggregation level based on the bandwidth violation trend, and may determine a second aggregation level based on determining that the flow suppression is not effective. The device may set the first aggregation level to the second aggregation level. The device may use the first aggregation level for aggregating additional incoming packets.

Abstract: A housing structure includes a main cabinet and a fixing mechanism. The main cabinet has an opening formed thereon and includes a side panel and a front panel. A groove is formed on the edge portion of the front panel adjacent to the side panel. A receiving slot is formed on the front panel and adjacent to the groove. The fixing mechanism includes a latch and an elastic member. The latch may be movably disposed on the side panel. A first hook is formed on the latch. When covering the opening with the side panel, the latch is abutted by the front panel. The restoration of the elastic member interlocks the side panel to the front panel securely to close the housing structure.

Abstract: The present invention relates to polyurethane, and specifically relates to a polyurethane microcellular elastomer, a method for preparing the same, and the use thereof. The polyurethane microcellular elastomer is the reaction product of (1) an isocyanate-terminated prepolymer obtained by reacting an isocyanate with a first polyol, (2) a second polyol, (3) a chain extender and (4) a catalyst, wherein the first polyol and/or second polyol comprise at least one polycarbonate polyol obtained by reacting carbon dioxide with an alkene oxide. This method of preparing polyurethane microcellular elastomer can not only reduce the demand for raw materials derived from petrochemicals, but also realize the utilization of the “greenhouse gas” carbon dioxide.
