The proposed framework is also applicable to any types of NPDs, including CNDP, DNDP, and MNDP.
Moreover, the UE constraint of the MNDP was defined from the extreme points of the link-flow feasible region.
As a result, the MILP problem was a link-based approach.
Hence, the explicit path enumeration and path storage can be obviated.
To solve the MILP problem, this paper also developed the solution algorithm based on the cutting constraint algorithm (CCA).
