Abstract
A method and apparatus for providing redundancy for an access network are disclosed. For example, the method receives an access network structure, and removes one or more unnecessary 2D edges or 3D edges from a simplex cover for the access network structure. The method then performs a search on the simplex cover; and, generates a new access network structure that includes the redundancy.
