Huawei Leads Network Cloud Standardization and Promotes the BBF to Release CloudCO Standards

Feb 23, 2018

[Shenzhen, China, February 23, 2018] The Broadband Forum (BBF) recently releases Cloud Central Office (CloudCO) architecture standards. These standards provide important references for operators in reconstructing broadband network architectures. The announcement of these standards is a key step towards implementing cloud network.

In 2016, Huawei first came up with the idea of CloudCO and initiated the standardization projects. Since then, Huawei has actively promoted the standardization of CloudCO scenarios, architectures, interfaces, and test specifications. Huawei has also helped the BBF establish open broadband (OB) labs in Asia, and has implemented CloudCO standards testing and integration verification, comprehensively accelerating the progress of international standardization of network cloudification.

In the CloudCO standards, the BBF redefines access and metro networks to build a cloud broadband platform with open interfaces, enabling operators to deliver new services effectively and to shorten service provisioning time. Under the CloudCO standards, traditional NE functions are decoupled and then migrated to the cloud.

These standards also define northbound application platform interfaces (APIs), so that operators can effectively implement automatic lifecycle management over all services and can support automatic service provisioning, network deployment, and maintenance. Taking the smooth evolution and upgrades of existing systems into consideration, CloudCO supports compatibility with these systems and designs relevant interfaces for them.

Currently, Huawei is actively pushing the application of CloudCO standards on live networks. In the access network field, Huawei has released the CloudFAN solution to create a brand-new access network architecture for the cloud era. This solution's OLT CO fabric and FAN sharing ideas have been incorporated into the CloudCO standards.

In the metro network field, Huawei has released the cloud-based BNG (Broadband Network Gateway) solution, which decouples the traditional BNG into the service control plane and forwarding user plane, forming an architecture with separated control and user. This architecture enables operators to manage service resource pools of the hybrid physical network function (PNF) and virtualized network function (VNF).

Building cloud networks is the trend for the ICT industry to become more open. The release of the CloudCO standards by the BBF is a milestone in this process. Based on the value proposition of network intelligence and simplification, Huawei will continue to contribute to standards organizations and industry organizations, work with partners to build a healthy cloud network industry ecosystem, and enable rapid growth in the industry.

MWC 2018 will be held from February 26 to March 1 in Barcelona, Spain. Huawei will showcase its products and solutions at booth 1J50 in Fira Gran Via Hall 1, booth 3I30 in Hall 3, and the Innovation City zone in Hall 4. For more information, please visit
