Top WAN Issues Faced by Globally Distributed Enterprises

This article outlines WAN problems faced by globally distributed enterprises—notably unreliable last-mile connections and high latency/packet loss between Asia Pacific (including China) and other regions—and describes cloud network (SD-WAN) architectures that combine multiple last-mile transports, regional PoPs, and tier-1 carrier backbones to improve performance, reduce packet loss, and provide centralized security and cost advantages over MPLS.
