First Claim
1. A method comprising:
- calculating a first packet error rate (PER) of a flow sent from a source to a cable modem over a first period of time in a full duplex cable network;
tagging the flow based on determining the first PER of the flow satisfies a tag threshold associated with the flow;
intercepting, at a selective proxy, a packet of the tagged flow;
storing a backup of the packet;
transmitting the packet to the cable modem;
determining the cable modem did not receive the packet; and
retransmitting the backup of the packet to the cable modem.

Abstract
A method in an embodiment includes calculating a first packet error rate (PER) of a flow sent from a source to a cable modem over a first period of time in a full duplex cable network, tagging the flow based on determining the first PER satisfies a tag threshold associated with the flow, and intercepting, at a selective proxy, a packet of the tagged flow. The method further includes storing a backup of the packet, transmitting the packet to the cable modem, determining the cable modem did not receive the packet, and retransmitting the backup of the packet to the cable modem. Further embodiments include dynamically calculating a second PER of the tagged flow based on a second period of time, determining the second PER satisfies a de-tag threshold, and revoking the tagging of the flow based, at least in part, on determining the second PER satisfies the de-tag threshold.
