  • Patent number: 10178085
    Abstract: Systems, devices and techniques for establishing a secure file transfer session for secure downloading of configuration files to a Demarcation device are disclosed. Communication is established with a first network device. A password challenge message is received from the first network device. A username is generated. A password is generated using the password challenge message and a locally stored salt key. The username and the password are communicated to a second network device via the first network device, to facilitate establishing a secure file transfer connection with the second network device.

  • Patent number: 9674035
    Abstract: Techniques for updating configuration of an Optical Network Unit (ONU) in an Ethernet Passive Optical Network (EPON) include receiving a notification that an updated configuration file is available for the ONU, obtaining the updated configuration file, performing a first validation of the updated configuration file for structural errors, determining changes between a current configuration of the ONU and the updated configuration file to identify ONU resources to implement to the changes, performing a second validation about whether the ONU resources to implement the changes are available or not at the ONU and applying the changes to the ONU when it is determined that the ONU resources to implement the changes are available at the ONU.

  • Publication number: 20130238770
    Abstract: Systems, devices and techniques for operating a server in an Ethernet passive optical network (EPON) include receiving a Dynamic Host Configuration Protocol (DHCP) control message from a demarcation device, processing the DHCP control message depending on a target mode of operation, such that when the DHCP control message is inconsistent with the target mode of operation, the DHCP control message is dropped and when the DHCP control message is consistent with the target mode of operation, the DHCP control message is forwarded to the EPON and indicating, to the demarcation device, the target mode of operation by including a Mode Select Option field in a DHCP response message to the demarcation device.
