Re: Upstream bandwidth usage

We are rolling out XGS-PON everywhere which is 10G symmetric. Just because the PON runs at 10G, doesn't mean you need to provision all of your customers at 10G. We have a range of residential packages from 150Mbps up to 1Gbps symmetric. The ONT is the same in all situations. There is no SFP cost,

This seems pretty unworkable. We would now all need to maintain large CG-NAT boxes in the network to decasulate the traffic from a source to the subscriber. It does seem like it would be fairly stateless, it is not improving things. Assuming the end host is sending traffic with the magic header

Do you have anything in the way of COPP on either box that may be dropping packets? I would imagine the issue is likely to be on the AS1k end. Additionally I see you have different interface speeds at each side. Is the thing in the middle at fault? ND is done using multicast. One final thing is
