Hi,

On 2017-10-29, at 11:33, Simon Pietro Romano <spromano@unina.it> wrote:
> Which is exactly what I’d call adding multipath capabilities to a protocol “by design”, rather than trying to add multipath after the protocol has been specified. I think that security should have taught us a lot, when it comes to distinguishing the "patch it” vs “think of it at design time” approach.

so we did add multipath to TCP later, and it was painful, but not because we had issues extending TCP's design - it was painful, because the Internet had ossified around a pretty detailed set of assumption about what TCP would look like on the wire.

With, QUIC, if we get the greasing right, that danger is mostly off the table.

Now, we can still mess up the design of QUICv1 so that adding multipath later would be harder than it needed to be, but I'm pretty confident it's enough on our mind that that won't happen.
