Based on the previous paper, a virtual network mapping algorithm with repeatable embedding over substrate nodes is summarized, in which, the virtual nodes in the same virtual network may be assigned to the same substrate node so that some virtual links don't need to be mapped to reduce the substrate link costs and improve the mapping effectively. Additionally, in the link mapping process, path splitting is introduced to make best use of some low bandwidth to make more virtual networks mapped, which is similar to the multi-commodity flow problem.
