Abstract
A graph G = (V, E) is called a hyper-ring with N nodes (N-HR for short) if V = {0,..., N - 1} and E = {{u,v}|v - u modulo N is a power of 2}. The following results are shown. We prove that the node-connectivity κ of an N-HR is equal to its degree, say δ, by presenting an algorithm for the explicit construction of δ node-disjoint paths connecting nodes s and t. The length of these paths is bounded by [logD]+3, where D is the positional distance between s and t. Finally, we show a node-to-node communication scheme for HRs that requires only [log D]+3 rounds, even in the presence of up to δ - 1 node failures.
