Finding a pair of edge disjoint paths in a graph, such that the lengths of each one of the paths is smaller than a given constant

I know how to find a pair of disjoint paths with the minimum sum of lengths (Surballe\'s algorithm). I also have a formulation of an ILP that solves the following problem, which generalizes my problem[详细]
