  • Patent number: 11431525
    Abstract: A method and system for processing network traffic data units (NTDUs) is disclosed. The method includes establishing a virtual tunnel between a wireless access point (WAP) and a network device. A NTDU is received by the WAP from a client device, and the virtual tunnel is identified upon which to transmit the NTDU based on a header of the NTDU according to a policy. The policy maps a portion of the header to a plurality of available virtual tunnels. The NTDU is transmitted, via the virtual tunnel, to the network device.

  • Publication number: 20220053007
    Abstract: A network manager manages a network topology. The network manager includes storage for storing a signature of a network device of the network topology. The network manager also includes a device state manager that obtains a signature of a device that participates in the network topology, the signature indicating that the device is operating in an undesired manner; makes a determination, based on signature, that the device should be in a quarantined state; in response to making the determination: generates a quarantine state update that indicates that the device is in the quarantined state; and sends, by the network manager, the quarantine state update to the device. The quarantine state update does not indicate how the quarantined state is implemented.

  • Patent number: 11044197
    Abstract: In general, embodiments of the invention relate to processing network traffic data units (NTDUs). More specifically, embodiments of the invention relate to processing NTDUs transmitted between client device and the one or more protected resources. The protected resources are logically surrounded by a perimeter, which is implemented as a set of network devices that manage the flow of NTDUs between client devices and the protected resources. The perimeter works in conjunction with a set of filtering devices to determine whether a given NTDU can ultimately be transmitted to, and processed by, a protected resource.
