The traditional UPP MINs (Unique Path Property MIN)-Omega, baseline, Multistage Cube Network-have usually been designed for constructing N×N MIN using (N/2) log2N(O(Nlog2 N)) SEs. So far the multiple path MINs have been realized by adding additional hardware such as extra stages or duplicated data links. This paper presents a new Multistage interconnection Network (MIN) topology called Hybrid MIN. Although the Hybrid MIN is constructed using only 2N-3(O(N)) SEs which is much fewer than that of the traditional MINs, the Hybrid MIN satisfies full access capability (FAC) and has alternative paths, since there exist alternative paths and the short cut path for the localized communication. It takes advantage of exploiting the locality of reference
