  • Maximum device access restriction at authenticator level
    Patent number: 11811765
    Abstract: A network device may receive a request to access a network from a client device. The network device may determine that the client device is authenticated based on a set of authentication credentials obtained for the client device. The network device may determine, based on the client device being authenticated, that a quantity of devices currently accessing the network using the set of authentication credentials is equal to a maximum quantity of devices permitted to access the network using the set of authentication credentials.

  • Supporting multiple authentication methods on a port of a network device at the same time
    Patent number: 11562062
    Abstract: A network device may receive, via a single port of the network device, a connection request from a user device and may obtain, based on the connection request, information related to an authentication history of the user device. The network device may determine, based on the information related to the authentication history of the user device, an authentication method to be used by the network device to authenticate the user device and may determine, using the authentication method, that the user device is authenticated. The network device may establish, based on determining that the user device is authenticated, an authenticated communication session with the user device on the single port of the network device. The network device may determine, using an additional authentication method, that an additional user device is authenticated and may establish an additional authenticated communication session with the additional user device on the single port.
