Then ER-X-SFP it is.

I intended to only shape on egress for this experiement.  Let downstream be handled by the BRAS's policies (Juniper ERX in our case).  Most of the customer "speed" complaints come from not throughput but latency.  And that latency is mostly ADSL/VDSL customers with large uploads to cloud services.  So I think that we will by handling the upstream better make a large improvement.  But, hey, I call it an experiemnt because it is an experiemnt.  If we see significant improvements by using IFB for downstream as well.  Then we will try to see what we can do to implement this.
