Abstract
Hypercubes are popular topologies of massive multiprocessor systems due to their super properties. Cross-cubes are significant variations of hypercubes and they have smaller diameters and higher fault-tolerant capability than hypercubes at the same dimensions. In this paper, we construct node-to-set disjoint paths of an n-dimensional cross-cube, \(C_{n}\), whose maximum length is limited by \(2n-3\). Furthermore, we propose an \(O(N \text {log}^{2}N)\) algorithm with a view to finding node-to-set disjoint paths of \(C_{n}\), where N is the node number of \(C_n\). And we also present the simulation results for the maximal length of disjoint paths obtained by our algorithm.
