Infrastructure Sharing: A Cost Effective Alternative for Resiliency in 4G-LTE Mobile Networks

With the fast growth of Internet and a new widespread interest in broadband networks, the unparalleled potential of Multi-Protocol Label Switching (MPLS) is leading to further research and development efforts. One of those areas of research is Path Protection Mechanism. An aim of the authors' ongoing research is to take pragmatic approach to the "Last mile" issue and provide a solution to improve resiliency primarily for 4G-LTE mobile networks by infrastructure sharing by making use of this mechanism between operators' backhaul networks.
