Network hierarchy constructs enabling instant global wide area network connectivity
This disclosure describes techniques and mechanisms for disclosure describes techniques and mechanisms for a central management plane to automatically create and assign system identifiers to network devices, thereby creating a global network hierarchy within a network. The techniques enable the use of a system identifier to be automatically generated and assigned, as well as configuration and network policies to be automatically generated based on the system identifier. Accordingly, the techniques enable automation of regional connectivity and policy application, a simplified manner of troubleshooting/debugging of any connectivity issues, and a simplified, aggregated view of statistic and analytics related to problems at site, sub-region, and region levels.
