The first ADN prototype demonstrated in Sigcomm 2016, bringing concept to implementation

[Florianopolis, Brazil, Aug 29, 2016] Huawei 2012 Labs have demonstrated its first ADN prototype in ACM Sigcomm 2016, the flagship conference in computer networks and communications. This ADN prototype demonstrates the business value of auto-slicing and dynamic resource allocation according to the requirements from applications and users, in the multi-user-multi-application scenario. The demo also shows that ADN can improve the satisfaction ratio of users by 3~5 times, compared to the traditional TCP/IP paradigm. ADN provides new network architecture for network operators to address the challenges of on-demand services and better network resource utilization imposed in the future era of universal connections.

The ADN prototype released in ACM Sigcomm 2016 conference is an automatic system implemented on general virtual switches, aiming at automatic resource scheduling based on the philosophy of being driven by applications. The demo illustrates three typical applications: a bandwidth-sensitive application (e.g., video streaming), a delay-sensitive application (e.g., gaming) and an application being the combination of the aforementioned two (e.g., VR applications). The demo shows how ADN guarantees the performance requirements of these applications over the same network, i.e. a total 20 flows from the three applications. It also demonstrates that thanks to the application classification and automatic slicing techniques of ADN, the QoE metrics (in terms of delay, bandwidth and satisfaction ratio) can be improved by 3~5 times, even when the network utilization is as high as 94%.

Guided by the information consumption theory, network control theory, and information dissemination theory, the ADN prototype has shown its capability in application awareness, intelligent control on the data plane, virtualization of resource, fast/slow control, and coordination techniques, which further prove the feasibility of ADN network architecture as well as its advanced features of intelligence and automation.

The ADN prototype shows how ADN is able to satisfy the QoE requirements of applications, and to meet the requirements of content providers, network operators and others, based on its principle of “application efficiency first” under the scenario where VR videos, vehicular connections, and IoT applicaitons coexist over a unique network.

Since its first announcement in 2015, Huawei has been continuously sharing its outcomes in ADN, e.g., ADN measurement architecture and ARP (Adaptive Randomized Parallelism) theory, with industrial and academic researchers. In ACM Sigcomm 2016 conference, researchers from Huawei 2012 labs elaborate the ADN prototype to extensive experts in networking research, as well as researchers and professors all around the world. Meanwhile, application scenarios, business models and key techniques are shared with all Sigcomm2016 attendees. The success of ADN demo in ACM Sigocomm 2016 indicates the transition from theory to reality, fulfilling the concept of user-centric and application-driven solution.
