Another nice "emerging" tool [I say emerging because it's been around forever but nobody implements it] to deal with this is Flowspec, using flowspec you can instruct your Upstream to block traffic with much more granular characteristics.
flowspec is essentially S/RTBH with layer-4 granularity (it can do some other things, as well). I certainly hope that vendors who've not yet implemented it will do so, it's a great tool, as you say. Even customer-triggered S/RTBH is very useful, and some ISPs have implemented it for their customers. ----------------------------------------------------------------------- Roland Dobbins <rdobbins@arbor.net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
