  • Packet reflection identification in CPE devices
    Patent number: 10021024
    Abstract: Methods, systems, and apparatus can be used to filter packet reflections. In various implementations, packets received on a subscriber side of a device having a source address identifying a service provider device can be dropped. In other implementations, portions of packets forwarded to a subscriber side of a device can be cached and compared to portions of packets received on a subscriber side of the device.

  • Specifying and enforcing IPV4 and IPV6 CPE limits
    Patent number: 9479440
    Abstract: Systems and methods can provide for specifying and enforcing IPv4 and IPv6 CPE limits in a modem device. In some implementations, such systems and methods can inspect a packet originating from CPEs behind a modem to determine whether the packet is an IPv4 or IPv6 packet. Such systems and methods can compare the packet source MAC address to determine whether the address exists in the IPv4 and/or IPv6 CPE tables. The modem can then perform varying actions based on IPv4 or IPv6 CPE limit enforcement mechanisms, thereby alleviating the problem of a single CPE limit enforcement policy for all CPEs.
