One Million Subscriber Sessions Established Using a Single BNG
[Paris, France, March 21, 2017] The international independent testing organization, European Advanced Networking Test Center (EANTC), has announced that Huawei’s CloudMetro solution has been successfully tested for metro broadband access scenarios. This test verified that the CloudMetro solution is able to establish one million subscriber sessions by using a broadband network gateway (BNG), and achieved a session establishment rate of 2600 sessions per second.
With the development of new services such as 4K and VR, traditional metro networks are facing more and more challenges. The first such challenge is the low resource utilization efficiency of traditional BNGs, limited by the tight coupling of the BNG control plane and forwarding plane not allowing the forwarding plane to reach its maximum performance potential. The second challenge is the long time to market (TTM) of new services, with a large number of devices needing to be updated in order to support the introduction of new features. The third is the complexity of operation and maintenance (O&M). Expanding the scale of networks is difficult — devices must be configured one by one, and quick and efficient network management and troubleshooting is hard to achieve.
Rising to these challenges, Huawei has introduced the innovative CloudMetro solution, which can build cloud-based metro networks that meet the needs of future network evolution.
EANTC validated the CloudMetro solution with regards to metro broadband access scenarios. The Network Cloud Engine component and the multi-service edge router in the CloudMetro solution were both tested. EANTC applied its strict test methodology based on two decades of experience, focusing on meeting service providers' typical business and technical requirements. Test areas included lifecycle management, performance and scalability, functionality, resilience, and security.
Huawei's CloudMetro solution performed well throughout the test. The Network Cloud Engine realized MANO-based automated deployment and lifecycle management, which greatly simplifies the challenge of network element management.
The Network Cloud Engine also achieved a capacity of one million simultaneously active subscriber sessions and a session establishment rate of up to 2600 sessions per second. In addition, EANTC verified that there was no interruption in user traffic during VM failure, and confirmed that the system was operational even when it was the victim of a persistent distributed denial of service (DDoS) attack.
"Huawei commissioned us to validate the high flexibility of its CloudMetro solution when deploying and managing large broadband access infrastructures. We witnessed that the key element of the CloudMetro solution is the separation of the control and user planes in a cloud-based architecture" said Carsten Rossenhoevel, Managing Director of EANTC. "EANTC has validated the automated deployment of the network cloud engine as well as the lifecycle management of virtual network functions (VNFs), and confirms Huawei's claims for supported subscriber session setup rate and session capacity."
For the results of this test, Huawei Router & Carrier Ethernet Product Line President Gai Gang said: "The solution's cloud-based architecture can cope with uncertainty during rapid service development, helping operators solve the problems of low resource utilization efficiency, long time to market of new services, and complex operation and maintenance issues. In addition, the architecture can provide on-demand Lego-style modular service provisioning capability, helping carriers implement fast service integration and accelerating service innovation."
The Huawei CloudMetro solution was successfully tested by EANTC, fully demonstrating Huawei's metro network evolution and cloud architecture innovation capabilities. Huawei is dedicated to providing the best-quality products and solutions to help global operators achieve digital transformation and business success.
The MPLS+SDN+NFV World Congress 2017 will be held from March 20 to 24 in Paris, France. At this congress, Huawei will showcase multiple cloud-based network solutions and explore the development trends of cloud-based networks with global operators and partners to promote cloud-based network transformation.
