Hi,
I just want to bring to your attention the below talk (I am too lazy to re-write the whole email for this slightly different audience).
Takeaway:
We'll see a lot of ECN enabled traffic in a few months. This shouldn't be a problem. I've been doing it to all my machines for 3-5 years without ill effects.
you'll also find all the networks that use the entire tos field as part of the hash key... that's not exactly something you notice when you have a 1:1 host to ip correspondence unless it leads to reordering. but with stateless load balancing you can. fortunately those networks are observably rare.
I recall when ECN first came out and firewalls would block it causing me issues on my Linux boxes sending list mail out. It was a small enough percentage that I mostly ignored it, but this will cause trouble for people who still haven't fixed their broken firewalls.
I encourage almost everyone on nanog to watch this talk.
