n real time based on traffic load thresholds and based on locations (e.g., policies that are triggered when there is heavy traffic on certain highways during certain time periods). Examples of a latency-sensitive IoT service are connected driverless cars where a decision needs to be made in a split second for turning at a signal light and analysis and decision making based on real-time video and telematics feed from drones.

Building the Network of the Future that are not latency sensitive are asset tracking and asset management where sensor data can be sent to a centralized location. In summary, broad deployments of cloud locations enable a service- oriented CN architecture and provide the flexibility to support new service models. A Next Generation "X" Core (NGxC) is AT&T's vision of the upcoming next-generation multiaccess packet core architecture and its functions. The "X" in NGxC indicates a multiaccess core. It means exploring the virtualization and integration of wireless and wireline core functions including layer 3 and above such as policy, authentication, signaling, etc. It is envisioned that the NGxC will make full utilization of the SDN/NFV technologies. The NGxC will have a modular architecture for composition and decomposition of NGxC VNFs. This will help in creation of an optimized NGxC instance for the specific need of a use case. It will perform most
