Network virtualization (NV) is widely considered as a key component of the future network and promises to allow multiple virtual networks (VNs) with different protocols to coexist on a shared substrate network (SN). One main challenge in NV is virtual network embedding (VNE). VNE is a NP-hard problem. Previous VNE algorithms in the literature are mostly heuristic, while the remaining algorithms are...
One main challenge in network virtualization is virtual network embedding (VNE). VNE is NP-hard. Previous VNE algorithms in the literature are mostly heuristic, while the remaining algorithms are exact. To make a trade-off between the heuristic and the exact, this paper proposes the algorithm VNE-RSOT, based on restrictive selection and optimization theory, to solve the VNE problem. The restrictive...
The main challenge in network visualization is known as so called virtual network embedding(VNE). Most proposed VNE algorithms are heuristic so far in the literature. This paper presents an exact algorithm based on the Integer Linear Programming(ILP) of optimization theory. The exact algorithm VNE-ILP is able to simultaneously map virtual nodes and virtual links of VNRs. The constraint of virtual...
