  • Patent number: 11611505
    Abstract: Techniques and mechanisms for compressing the size of SIDs to be smaller than a complete IPv6 address (or “micro SIDs”), and scaling micro SIDs across a multi-domain environment using micro SID-domain-blocks. Segment routing over IPv6 (SRv6) uses 128-bit IPv6 addresses as SIDs for segment routing. According to this disclosure, multiple SRv6 SIDs may be expressed in a compact format such that a 128-bit IPv6 address, such as the destination address field of the IPv6 header, may store multiple micro SIDs. Further, SID-domain-blocks may be assigned to each domain in a multi-domain network such that micro SIDs may be expressed in the context of a given domain, rather than being shared in the global multi-domain network. In this way, lists of domain-specific SIDs may be fully expressed in the IPv6 destination address of the packet to scale micro SID into large, multi-domain networks.

  • Patent number: 11611579
    Abstract: In one embodiment, a device in a network captures domain name system (DNS) response data from a DNS response sent by a DNS service to a client in the network. The device captures session data for an encrypted session of the client. The device makes a determination that the encrypted session is malicious by using the captured DNS response data and the captured session data as input to a machine learning-based or rule-based classifier.

  • Patent number: 11611974
    Abstract: Techniques for uplink scheduling in a wireless network are disclosed. A wireless access point (AP) receives, from a wireless station (STA), a buffer status report (BSR) reflecting data accumulated at the STA for uplink to the AP. The AP identifies, based on the BSR, a scheduling mode under which the data was accumulated at the STA. The AP schedules an uplink parameter for the STA, based on the identified scheduling mode. The uplink parameter relates to at least one of: (i) an uplink transmission for the STA or (ii) a buffer status poll for the STA. The AP transmits, to the STA, an allocation relating to the scheduled uplink parameter for the STA.

  • Publication number: 20230084649
    Abstract: Optimal determination of a Wireless Local Area Network (WLAN) sounding method and system may be provided. An Access Point (AP) selects a subchannel for the partial sounding. The AP then sounds the selected subchannel. A client station responds with Channel State Information (CSI). The AP can receive the CSI, from the client station, in response to the sounding. Based on the CSI from the selected subchannel, the AP extrapolates the CSI to determine predicted CSI for a wider bandwidth channel.

  • Patent number: 11606366
    Abstract: In one embodiment, a sender node in a serial network identifies a message identifier for a packet to be sent by the sender node. The sender node selects a cyclical redundancy check (CRC) initialization vector associated with the message identifier. The sender node generates a CRC value for the packet, based on the selected initialization vector. The sender node sends the packet via the serial network. The sent packet includes the message identifier and the generated CRC value. In turn, a receiver node that receives the packet uses the generated CRC value to authenticate the sender node.
