I think the spoofed source filtering is more a red-herring than anything
else. Its not the fix for anything related to this problem of attacks on
the internet. Spoofed or non, I can forward 1,000,000pps at your network and
it will die (most times).

This is like trying to fix a rotten decayed tooth with trident.
