  ABSTRACT: We consider the problem of packing edge-disjoint cycles in digraphs. It is shown that for k=2,3 , any digraph with minimum degree k contains at least k+1 edge-disjoint directed cycles of size ≥k . In each of these two cases, examples are given to show that k+1 edge-disjoint directed cycles is the best we can achieve. These results are applied to obtain approximation algorithms for k -node-connectivity problems.
