In this paper we study the topological equivalence problem of multistage interconnection networks (MINs). We prove a new characterization of topologically equivalent MINs by means of a novel approach. Applying this characterization to log N stage MINs we completely describe the equivalence class which the Reverse Baseline belongs to. Most important, we apply the characterization to (2 log N - 1) stage MINs obtained as concatenation of two log N stage Reverse Baseline equivalent MINs: in this way, we deduce an O(N log N) time algorithm testing the equivalence of two such MINs. This result substantially improves the time complexity of the previously known algorithms (O(N4 log N)). Finally, we determine the number of different equivalence classes of (2 log N - 1) stage MINs and we characterize each of them. |
