%X <p>In order to withstand and recover from concurrent multi-link failures in optical networks, a <em>k</em>-regular and <em>k</em>-connected structure based protection mechanism was proposed. Analysis shows that the <em>k</em>-regular and <em>k</em>-connected structure is an optimal protection structure in link-restorable mesh networks under multi-link failures. The linear programming model (ILP) for <em>k</em>-regular and <em>k</em>-connected structure and a construction method for <em>k</em>-regular and <em>k</em>-connected structure design were proposed. Simulations indicate that the spare capacity efficiency of <em>k</em>-regular and <em>k</em>-connected structure can reach the lower bound in static networks, and it can largely improve spare capacity efficiency compared with p-cycles based protection structure without reducing recovery rate under dynamic traffic.</p>
