UDP clamped on service provider links

[glen.kent at gmail.com (Glen Kent)]

Hi,

Is it true that UDP is often subjected to stiffer rate limits than TCP? Is
there a reason why this is often done so? Is this because UDP is stateless
and any script kiddie could launch a DOS attack with a UDP stream?

Given the state of affairs these days how difficult is it going to be for
somebody to launch a DOS attack with some other protocol?
