Re: [v6ops] draft-xie-v6ops-network-happyeyeballs

Jordi, 

It is not unusual that operators deploying IPv6 monitor both IPv4/IPv6 performance metrics to track and detect severe gaps. 

Nevertheless, that probing does not allow to ** deterministically ** conclude that the root of the problem is at the server side (proxy, CDN, etc.). 

Gaps in v4/v6 metrics is used as one of the problem detection triggers among others: the problem may be caused by a misbehaving router/node on IPv6 packets, local forwarding issues, congestionned links with a peer/transit providers, etc. Of course, in some cases the content provider is contacted to solve the problem by tuning, for example, how the traffic is delivered to the network provider. 

So, sending an automatic report to some server may not help solving the problem.

Cheers,
Med
