[OpenSIPS-Users] Optimal trunk capacity filling algorithm or capacity-aware LCR

I'm looking for a solution to a problem that is not OpenSIPS specific, but
for sure some of you have dealt with this, and maybe someone can suggest
optimal solution, so I could not re-invent the wheel
It's all about proper filling of available termination trunk capacity, but
not the trivial one with simple LCR
Let's say we have two trunks:
- Trunk 1 - capacity 100 channels, termination cost 1 cent
- Trunk 2 - capacity 200 channels, termination cost 3 cent
And we have clients sending wholesale traffic with random number of
- Client 1 - sell rate 2 cent
- Client 2 - sell rate 4 cent
As you see we can only sell to client 1 with profit using trunk 1. If we
use LCR and client 2 has more traffic, than it will fill trunk 1 capacity
and client 2 will hit trunk 2 and we will start to loose money
Sticking client 1 to trunk 1 and client 2 to trunk 2 is also not optimal.
Number of channels is more or less random. If we stick client 2 to trunk 2
when client 1 is not using all 100 channels, than we loose additional 1
cent of margin
I think about some form of capacity-aware dynamic routing - send client 2
traffic to trunk 1 only if client 1 cannot fill trunk 1, maybe using some
capacity averages from last X minutes.
Any suggestions how to approach this problem?
