Fengwei,

I would be glad to address your concern regarding CRH forwarding efficiency by demonstrating our ASIC-based implementation. Please contact me off-line to set up the demo.

                                                                                                            Ron

[External Email. Be cautious of content]


Chairs,

There are indeed many problems unclarified in the CRH solution and I think it is too early to talk of adoption.
As a operator, there many points of great concern, such as the low forwarding efficiency, security issue, etc, required further clarification.


Thanks,
Fengwei Qin

    Ole and I are discussing this tomorrow.

If you are reviewing this today ( I presume you are doing it now), can you consider the following:

There have been many outstanding technical comments that authors have not addressed (this is a partial list).
