What vendors support > it? The only thing that's *required* for it to help is that the routers and firewalls not actually *molest* the bits in the TCP SYN packet. If you pass them and *do nothing else*, it at least has the potential of being useful at some other router along the path. And let's face it - if *your* router is congested enough for ECN to matter, there's a fairly good chance that the router one hop up/downstream is *also* seeing some effects. Even if *you* don't do anything else, your neighbor might - helping you out in the bargain. Attachment:
