Well that's an engineering failure - unless, of course, non-TCP/IP traffic is predominant in the environments these are put into.  In any case, this is not a solution for the Internet.

> On another page, cheap, widely deployed Broadcom L3 ASICs (found in the low-end hardware of major network vendors) support RED in hardware - however, OEM firmware typically doesn't allow the configuration of the full feature set. (DCTCP as a TCP-based QCN-like was demonstrated with custom broadcom firmware doing the ECN marking based, soley based on current queue depth).

Ah, market segmentation, how do I hate thee?  Let me count the ways.
