Cloud Central Office (CloudCO)


Broadband Forum CloudCO Projects

Cloud Central Office (CloudCO) is a recasting of the Central Office hosting infrastructure that utilizes SDN, NFV and Cloud technologies to support network functions and is aligned with the BBF 20/20 vision. In doing so, it radically redefines the architectures of the access and aggregation networks that have developed incrementally in previous Broadband Forum specifications such as TR-101 and TR-178.

The CloudCO’s functionality can be accessed through a northbound API, allowing Operators, or 3rd parties, to consume its functionality, while hiding how the functionality is achieved from the API consumer.  In order to achieve this, SDN & NFV are leveraged, running on a cloud-like infrastructure deployed at Central Offices.

CloudCO Reference Architectural Framework TR-384

This specification defines the reference architectural framework of the CloudCO. Functional Modules are defined, but not the details of their internal operation. This framework starts from basic Northbound API capabilities so that function composition, initialization, and management of the CloudCO resources can be supported and created as a byproduct of end-to-end service composition.

This specification is the first phase in a multiphase project. Additional work is underway to include migration, detailed interface definitions, test cases & application notes, use cases & scenarios and reference implementations. Progress on hese projects can be seen on the BBF members sites:
