    Abstract: Systems and methods for restoring lost or corrupted data in packets that traverse a packet-switched network. In some embodiments, a device at the edge of a packet switched network may restore data that was originally inserted in a packet header by a sender, but overwritten or bleached during transport over a network by identifying an associated packet, and transferring a value from the associated packet to the packet.

    Abstract: A network device receives an IPv4-in-IPv6 packet. An IPv6 header is removed. A first DSCP value in a TC field and a second DSCP value in a ToS field is stored in a database. The IPv4 packet is forwarded upstream and a return IPv4 packet is received. The returned IPv4 packet is encapsulated to form an IPv6 packet. The first DSCP value and the second DSCP value are retrieved from the database. Based on the at least one policy, the second DSCP value is inserted into an IPv4 ToS field and into an IPv6 TC field, the retrieved second DSCP value is inserted into the IPv4 ToS field and the first DSCP value is inserted into the IPv6 TC field, or the first DSCP value is inserted into the IPv6 TC field and into the IPv4 ToS field. The network device then forwards the IPv6 packet downstream.

    Abstract: A MAP-T system that shares an IPv4 address with one or more other MAP-T systems identifies low latency (LL) traffic for an upstream and a downstream perspective by enhancing NAT of ports using MAP-T rules. The MAP-T rules provide a range of transport ports with a transport slice providing for a subdivision of the transports into a subnet range so as to isolate certain ports for mapping LL traffic. An access point device and a cable modem of the MAP-T system are configured so as to appropriately transform any received traffic so as to properly direct the traffic.

    Abstract: A Wi-Fi APD is configured to tag internet protocol data with a first priority level and a second priority level that is higher than the first priority level. The network controller contains a memory that contains a channel bandwidth threshold value. The network controller contains a processor configured to execute instructions that cause the network controller to: periodically poll the Wi-Fi APD; periodically receive poll responses from the Wi-Fi APD; determine whether channel bandwidth is greater than the stored channel bandwidth threshold value; determine whether the response time of the poll responses is greater than the polling period; and instruct the Wi-Fi APD to tag internet protocol data with the second priority level when at least one of the channel bandwidth is less than the channel bandwidth threshold value and the response time is greater than the period of the first frequency.

    Abstract: A server device for use with a cable modem, a router, a user, a client device, and a CMTS, the cable modem and the router being able to be configured in a LAG configuration, the client device and/or the cable modem being configured to provide a notification to the user to configure the cable modem and the router into the LAG configuration, the CMTS being configured to provide a first and second service flow to the cable modem, the server device comprising: a memory; and a processor configured to execute instructions stored on the memory to cause the server device to: monitor the second set of data packets; and automatically transmit a LAG notification to the client device and/or the cable modem when the second set of data packets meets a predetermined threshold, the notification notifying the user to configure the cable modem and the router into the LAG configuration.
