China Mobile Focuses on SDN for Private Cloud DevOps

By Tara Seals July 16, 2015

China Mobile has deployed Nuage Networks’ software-defined networking (SDN) technology in its Development and Operations (DevOps) private cloud architecture, with the aim of federating the operator’s multiple, disparate networks.

“China Mobile is taking a visionary approach in designing and building its new DevOps private cloud architecture,” said Nuage Networks CEO Sunil Khandekar. “By combining open-source software with Nuage Networks VSP, China Mobile is replacing and surpassing its previous legacy architecture in terms of power, sophistication and choice. It will change the way China Mobile operates internally and, ultimately, the cloud services they can provide to customers. ”

Based on open-source software and industry-standard hardware, China Mobile’s private cloud architecture is using Nuage Networks’ Virtualized Services Platform (VSP) as an overlay to unify China Mobile’s existing widely distributed networking environments.

Each subsidiary is allocated its own Virtual Private Cloud (VPC), composed of resources located in one or multiple datacenters. These are then connected and accessible anywhere in the cloud. Meanwhile, Nuage Networks Virtualized Services Assurance Platform (VSAP) provides visibility between the virtual and physical environments for each VPC and the federated cloud.

Each VPC is also isolated and secure – internally and externally – at the virtual machine (VM) level using Nuage Networks VSP’s network micro-segmentation capabilities, which protect against “east-west” malware penetration attempts within each datacenter, within each VPC and within the federated cloud. Datacenter communications between hypervisors are also protected.

While China Mobile’s cloud team may prevent subsidiaries from overriding centralized security policies, each subsidiary may refine security parameters within its allocated VPC.

The VSP will not only be used to support its internal subsidiaries, but also for developing new cloud-based services. To that end, China Mobile also this week collaborated with Nuage parent Alcatel Lucent on a field trial of a virtualized radio access network-based architecture based on network functions virtualization (NFV) technology.

The trial – carried out at Beijing’s Tisinghua University – aimed at greater network convergence, better spectral efficiency, support for more users, higher data rates and a more consistent user experience for next-gen mobile services. The trial provided both indoor and outdoor coverage and demonstrated the flexibility of the vRAN network, including its ability to dynamically scale network resources in response to traffic demands by the users across the campus.
