Wireless Wireline Convergence in the Single Stack Era Over the past three decades, communications service providers (CSPs) have undergone several notable network technology-driven transformations in their fixed and mobile networks. These include the evolution from time-division multiplexing (TDM) digital-based legacy networks to IP-based networks. The most recent evolutionary trend is the shift from IP-based non-cloud-based networks to IP cloud-native networks. This shift to IP cloud-native networks is profound on many levels since it enables truly elastic-scale, ultra-low latency performance. Perhaps most importantly, it also supports the software-enabled delivery of a common harmonized single stack of fixed and mobile services known as wireless wireline convergence (WWC).
