I'm a little bit surprised that the RTG area load has gone up like this,
and so quickly. Is it the various SDN things that are pushing this, or is
it
that the RTG area currently has the most enthusiasm for YANG work?
It's a mixture of things combined with RTG already being at the very top edge
of workload. In RTG we have/will have about 21 active WGs; if we add a
third routing AD,
then RTG will absorb 3 WGs from INT. Granted that one is not active and may
be merged in, we are still looking at about 23 WGs for RTG with a more
average load being about 8 WGs/AD.
So let's be frank about this. Today (excluding the General Area AD
with his crippling load of 1 WG) we have 129 WGs for 14 Ads,
which is 9.2 WGs/AD. That is clearly too many, so should there
be a target ratio and a plan for reaching it?
I don't think so. There are just huge differences in how different
WGs impinge on AD workload. I think we should look to try to spot
any imbalances that exist and adjust where needed. We do that already
within the SEC area, and ADs in other areas also do, but I don't
think we can use a number-of-WGs-per-AD metric except as the most
coarse grained measure. (And the out-of-area AD thing gives us
another tool to balance workloads.)
