  • determining a traffic history for a user of the internet;

    identifying wanted traffic in a stream of internet traffic based on the traffic history;

    prioritizing the wanted traffic such that unwanted traffic is assigned a lower priority than the wanted traffic, anddefining a heuristic, wherein identifying and prioritizing are performed based on the heuristic and wherein the heuristic comprises;

    a low port number heuristic that defines traffic in the stream of internet traffic as wanted traffic if any port numbers involved in a connection are below 1024;

    a low packet count heuristic that defines traffic in the stream of internet traffic as wanted traffic if five or fewer packets are seen in a flow; and

    a reverse flow seen heuristic that defines traffic in the stream of internet traffic as wanted traffic if a flow has been seen between a same pair of IP addresses in an opposite direction within a previous seven day period,wherein determining, identifying, prioritizing and defining are performed by at least one processor.
