1. A method comprising:

  • receiving, by a plurality of geographically dispersed network field units that control respective portions of an edge network of a plurality of geographically dispersed data centers, corresponding network service definitions from a centralized network controller (CNC) system, wherein the corresponding network service definitions each specifies different end-to-end network service requirements to implement a different end-to-end network service within a different one of the portions of the edge network, wherein the respective portions of the edge network within the plurality of geographically dispersed network data centers connect through one or more cloud-based service exchange points of the plurality of geographically dispersed network data centers, wherein the one or more cloud-based services exchange points are coupled to respective cloud service provider networks within the respective portions of the edge network;

    determining, by each network field unit of the plurality of geographically dispersed network field units and based on the corresponding network service definition received by the network field unit, one or more particular, physical devices of the portion of the edge network controlled by the network field unit that are usable to provide the end-to-end network service specified by the corresponding network service definition;

    configuring, by each network field unit of the plurality of geographically dispersed network field units, the one or more particular, physical devices of the portion of the edge network controlled by the network field unit to provide the end-to-end network service specified by the corresponding network service definition;

    receiving, by each network field unit of the plurality of geographically dispersed network field units and from the CNC system, corresponding requests for service assurance of the network service specified by the corresponding network service definition; and

    providing, by each network field unit of the plurality of geographically dispersed network field units, the service assurance of the end-to-end network service specified by the corresponding network service definition received by the network field unit by (1) obtaining service telemetry and analytics data for the end-to-end network service specified by the corresponding network service definition received by the network field unit and from the corresponding cloud-based services exchange point, (2) analyzing the service telemetry and analytics data to identify at least one anomaly for the end-to-end network service specified by the corresponding network service definition received by the network field unit, and (3) in response to identifying the at least one anomaly, executing a remedial action to ensure the end-to-end network service specified by the corresponding network service definition adheres to a service level agreement associated with the end-to-end network service specified by the corresponding network service definition received by the network field unit.
