EdgeUpdateMode
Special modes for updating links.
@ Refresh
Refresh capacity.
@ Unrestricted
Use unrestricted link.
@ Increase
Increase capacity.
@ Restricted
Use restricted link.
DistributionType
@ DT_MANUAL
Manual distribution. No link graph calculations are run.
@ DT_ASYMMETRIC
Asymmetric distribution. Usually cargo will only travel in one direction.
@ DT_SYMMETRIC
Symmetric distribution. The same amount of cargo travels in each direction between each pair of nodes...
@ DT_MAX_NONSYMMETRIC
