1. An error resilience method comprising:
using a computer, creating and storing, in computer memory, a FEC filter table for use by a FEC filter for selectively forwarding a FEC packet;
selectively forwarding a request for the FEC packet through the FEC filter based on the FEC table and a dynamic packet loss level at a receiver; and
limiting a re-transmission request for a particular packet through the FEC filter based on a number of re-transmission requests for the particular packet,
wherein the method is performed by one or more special-purpose computing devices.
