Corrupt packets would be treated as lost. Note first that if the IP header is corrupted, then the packet must be discarded. Second, for many implementations, if some fields outside the IP header are corrupted, it may be very clumsy for the implementation to do anything other than discard it. Third, it would be complex and arbitrary to specify in the metric that some corruptions were OK and others not. Guy and Vern together noted that other Streams could be defined, but that many of the obvious alternatives are subject to biases.
Packet filters can suffer from a wide variety of errors, such as drops, additions, and reorderings.
