![]() Verizon’s use case has wide applicability to many other operators. ![]() Underscoring the point that CEM is ready today, we provide a case study of Verizon’s circuit-to-packet modernization using CEM with MPLS, which is being deployed today. This white paper discusses the modernization challenge and presents CEM over MPLS-based networks as the most promising solution for operators and their customers. Fortunately, circuit emulation (CEM) has emerged as a means of circuit-to-packet migration, though many operators may not yet be aware of its scalability or its benefits. For years, oper-ators had few architectural options for network modernization. Operators are struggling to manage their aging SONET/SDH infrastructure, much of which has exceeded its intended lifespan and become a serious operational strain.
