Get the effective supply of one node towards another one.
In symmetric distribution the supply of the other node is weighed in.

to | The receiving node. |

Check if there is any acceptance left for this node.
In symmetric distribution nodes only accept anything if they also supply something. So if undelivered_supply == 0 at the node there isn't any demand left either.
to | Node to be checked. |

void SymmetricScaler::SetDemands | ( | LinkGraphJob & | job, |
NodeID | from_id, | ||
NodeID | to_id, | ||
uint | demand_forw | ||
) |
Set the demands between two nodes using the given base demand.
In symmetric mode this sets demands in both directions.
job | The link graph job. |
from_id | The supplying node. |
to_id | The receiving node. |
demand_forw | Demand calculated for the "forward" direction. |
