Abstract
Techniques are provided for the controlled scheduling of the authentication of devices in a lossy network, such as a mesh network. An authenticator device that is configured to authenticate devices in a lossy network receives an authentication start message from a particular device to be authenticated. The authenticator device determines a schedule for engaging in an authentication procedure for the particular device based on an indication of current network utilization.
Claims35
A method comprising:
- at an authenticator device that is configured to authenticate devices in a lossy network, receiving an authentication start message configured to initiate an authentication procedure from a particular device to be authenticated;
- at the authenticator device, delaying the authentication procedure and determining a schedule for engaging in the authentication procedure for the particular device based on an indication of current network utilization;
- transmitting across the lossy network from the authenticator device to the particular device an authentication request message configured to re-initiate the delayed authentication procedure;
- and
- receiving a re-initiating authentication start message from the particular device.
An apparatus comprising:
- a network interface unit configured to enable communications over a wide area network;
- a transceiver unit configured to transmit and receive signals over a lossy network;
- a processor coupled to the network interface unit and transceiver unit, the processor configured to:
- receive an authentication start message configured to initiate an authentication procedure, from a particular device to be authenticated,
- delay the authentication procedure and determine a schedule for engaging in the authentication procedure for the particular device based on an indication of current network utilization,
- transmit across the lossy network an authentication request message configured to re-initiate the delayed authentication procedure to the particular device;
- and
- receive a re-initiating authentication start message from the particular device.
One or more tangible, non-transitory computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
- at an authenticator device configured to authenticate devices in a lossy network, receive an authentication start message configured to initiate an authentication procedure from a particular device to be authenticated;
- delay the authentication procedure and determine a schedule for engaging in the authentication procedure for the particular device based on an indication of current network utilization,
- transmit across the lossy network an authentication request message configured to re-initiate the delayed authentication procedure from the authenticator device to the particular device;
- and
- receive a re-initiating authentication start message from the particular device.
