1. A method for finding shared risk diverse paths, the method comprising:

  • receiving route information at a node;

    running a shortest path algorithm to identify a first path;

    assigning shared risk metrics to links and nodes within said first path;

    running the algorithm with the shared risk metrics assigned to identify a second path; and

    comparing said first and second paths and assigning new shared risk metrics to links and nodes in said second path if said first and second paths are not diverse.
