Migrating away from legacy networking technologies is always a challenge. But done right, the process can lead the way to better and higher performing infrastructure that benefits both end users and network operators. The challenge and opportunity are of strategic interest to network operators today as they transition away from TDM technologies—which are rapidly going obsolete—toward IP/MPLS approaches. These deliver the best-possible system performance at all times, guarantee their ability to support legacy customers and new business services, and help operators pursue emerging opportunities, such as backhaul for 5G.
