Mirja and Colin, We need to make progress on resolving this Discuss. To my understanding where we stand are that Mirja thinks that Circuit breaker should not state that ECN CE marks should not result in the same response as a packet loss provides. Colin disagree and base that on the current in force Standards Track document (RFC3168). From my view, I do understand Mirja's view that this is likely not where we want to be in the future when it comes to response to ECN CE marks. However, at the same time, there is not yet a even a WG item for addressing this and changing the current ECN specification. There doesn't yet exist even a WG consensus on what the desired response to ECN CE marks are. Blocking the publication of the document for referencing what it the current in force specification is not a reasonable discuss in this case. The suggestion that there should be another specified behaviour for ECN CE marks for the algorithm in circuit breakers is hard to perform without a IETF consensus for what the desired response to ECN CE marks is. I also note that if circuit breakers would like to define another behaviour to ECN-CE marks, it would need to update the existing MUST in ECN specification. We can't simply ignore the MUST in RFC3168 simply because it doesn't suit us. Thus requiring the circuit breaker document to achieve the IETF consensus on the ECN change. This may very likely cause a minimal 1 year delay, more likely 2 years before we have an IETF consensus on this question. This for a document that is already have a significant missref queue behind it. What I think is reasonable is to pave the way as good as possible for the future change. Do a much by reference to the current in force specification. But, I fear that we will not be able to avoid doing an update on circuit breaker when the new ECN-CE behaviour has been agreed. Does this sound like a reasonable way forward?
