  • Patent number: 11032314
    Abstract: In one embodiment, a security service classifies traffic telemetry data for traffic between an endpoint device and a server as potentially associated with a particular type of remote access Trojan (RAT). The security service constructs a scan message to elicit a type of server response associated with the particular type of RAT. The security service obtains a server response from the server, by sending the constructed scan message to the server. The security service determines whether the endpoint device is infected with the particular type of RAT, by validating whether the server response from the server matches the type of server response associated with the particular type of RAT.

  • Patent number: 11032820
    Abstract: Receiving Wireless Local Area Network (WLAN) packets from co-located access point radios and client device radios may be provided. First, a plurality of switchable gain devices corresponding to an auxiliary radio may be placed into a toggling state in response to the auxiliary radio being placed in a sniffer mode. Next, it may be determined that a primary radio is transmitting within a frequency range of a frequency band. Then, in response to determining that the primary radio is transmitting within the frequency range of the frequency band, a one of the plurality of switchable gain devices corresponding to the frequency band may be placed into a low gain state when the auxiliary radio is sniffing the frequency range of the frequency band.

  • Patent number: 11032193
    Abstract: Presented herein is an “In-situ OAM” (IOAM) mechanism that uses a Segment Routing-Multiprotocol Label Switching (SR-MPLS) IOAM segment identifier that can selectively collect IOAM data from “target” network nodes along a data packet path. In one embodiment, a method includes receiving, at a first network node in the SR-MPLS network, a data packet that includes an MPLS label stack comprising a plurality of segment identifiers (SIDs) associated with a plurality of network nodes. The MPLS label stack includes a first SID associated with the first network node. The method includes determining whether the first SID is an IOAM SID or a regular SID. Upon determining that the first SID is the IOAM SID, the method includes implementing an IOAM function at the first network node. Upon determining that the first SID is the regular SID, the method includes processing the data packet without implementing an IOAM function.

  • Patent number: 11029891
    Abstract: Techniques are provided for storing data in a distributed storage system. A server stores an object according to a first storage policy in the distributed storage system that includes a plurality of storage nodes. Storing the object according to the first storage policy results in a first storage overhead for the object. The server receives a triggering event associated with the object, and the triggering event changes an attribute of the object. In response to the triggering event, the server identifies a second storage policy for the object. Storing the object according to the second storage policy results in a second storage overhead for the object different from the first storage overhead.

  • Patent number: 11031938
    Abstract: In one embodiment, a device in a low-power and lossy network (LLN) makes, based on a temperature measurement, a first adjustment to a frequency for a wireless channel used by the device to communicate with one or more neighboring devices in the LLN. The device receives, via the wireless channel, a packet from one of the neighboring devices that indicates a transmit frequency for the packet. The device calculates a frequency offset based on a difference between the transmit frequency for the packet and the adjusted frequency for the wireless channel. The device makes, based on the calculated frequency offset, a second adjustment to the frequency for the wireless channel used by the device to communicate with the one or more neighboring devices in the LLN.

  • Patent number: 11025489
    Abstract: Techniques for automated analysis and classification of network configurations are provided. Resource provisioning code used to provision resources in a network is received, and a set of constraints is generated based on the resource provisioning code, where the set of constraints define valid network configurations. A configuration tree for the network is received, and a set of candidates is generated for the network based at least in part on the configuration tree. Upon determining that a first candidate of the set of candidates does not fail any constraint in the set of constraints, the first candidate is recorded as a manual intent. The manual intent is integrated into an automated configuration system for the network.

  • Patent number: 11022757
    Abstract: Embodiments herein describe a photonic platform where an AR coating is disposed between an optical grating and a semiconductor substrate. In one embodiment, the optical grating is disposed within an insulative layer. A first side of the insulative layer provides an optical interface where an external optical source can transmit an optical signal into, or a receive an optical signal from, the grating. A second, opposite side of the insulative layer contacts the AR coating. When the external optical source transmits light through the first side of the insulative layer, some of the light passes through the grating and reaches the AR coating. The AR coating prevents this light from being reflected back to the grating by the semiconductor layer which can cause interference that varies the coupling efficiency of the grating.
