Further, if flex-algo is already in use, do you also need
per flex-algo OFA topologies so as to maintain the
optimization objective for the flex-algo topology you’re
off-loading from?
##PP
depends, you can share the same OFA for multiple FAs, or you can have
unique OFA for each of them.
It is not always required to offload the traffic for all algos - e.g.
offloading the best effort traffic only may be sufficient in many cases.
I am not sure I read this properly. It looks like you are saying that
you only need as many OFP flex-algos as the number of flex-algos
needed to relieve the congestion.
##PP
no, what I'm saying is that you do not need to use DCM for all algos.
If you have an algo-0 best-effort traffic, which tends to be bursty and
that represents 80% of your traffic, and 20% of the FA specific traffic
which is a low latency traffic, you may decide to use DCM for algo-0
traffic only. If the link becomes congested, you only offload the best
effort traffic.
thanks,
Peter
During congestion remediation, that seems to be the case. But I think
the flex-algos need to be defined at configuration time and consume
router resources at all times, not just when you decide to remediate
congestion. So the fact that a given event may only need 1 extra does
not remediate the need for N+1 extra when vvbest effort plus n
flex-algos are already in use. Have I read this properly?
Yours,
Joel(for full disclosure, working for HPE)
