Well, it would help if operators tried to buy CPEs taht were not only
bare-minimum for what they need today.
I think the problem is a bit more complex. For what concerns queuing
the chipcos
do a lot of offloading in silicon. This is an entire industry choice and
that silicon
is programmable but opaque and not open.
If chipcos made that choice there is a reason.
Right now I hear more about "virtualised CPE" to save cost (ie move
part of the CPE implementation to the data center) than to spend more
money on features in the CPE.
That won't solve the problem discussed in this list. I like the approach
though.
My hope is still on the mobile phone SoCs trickling down to the home
gateway space so we get more CPU power there at decent price point.
Also possibly that the whole SDN movement means hardware will get
standardized APIs so in case there is hardware acceleration on the
CPE, this can be handled by any kernel and not just the kernel that
the vendor has modified to work with their special hardware.
I don't how SDN would help for queuing.
DPDK, netmap instead would help but we are far from having that kind of
support in CPEs.
