First Future Network ADN Forum Is Hosted in Hong Kong to Rapidly Realize Future Network Concepts

The First Future Network ADN Forum was hosted at the Hong Kong Science Park, from June 21 to 22. More than 10 leading network experts and enterprise CEOs shared their thoughts on visions and architectures for ADN, as well as progress in business models, prototype verification, scenario-specific applications, and key technologies. Attendees included more than 100 university professors, scholars, and industry experts.

Business models for future networks must meet the requirements of content production, content operation, and network operation. At the forum, several professors shared their theoretical research results concerning the feasibility of differentiated service models.

Their theories have shown that Application-driven Network (ADN) architecture can offer multiple benefits under typical Internet scenarios. It will allow Internet service providers to deliver differentiated services, content providers to pursue continuous service innovation, regulators to formulate specific regulatory policies based on service types and also allow consumers to enjoy a superior service experience.

During the session on innovative architecture for future networks, expert speakers and attendees engaged in lively discussions on Software-defined Networking (SDN), beyond SDN, Named Data Networks (NDN) and Information Centric Networks (ICN). Future networks will face the challenge of ensuring service performance and capacity expansion under ultra-large heterogeneous network architecture. Future network architecture must support application awareness at the service layer and smart control at the data plane. The ADN architecture is able to allocate optimal network resources for different services in a dynamic network environment. Therefore, ADN is an ideal network architecture that helps users, operators, and equipment vendors to achieve shared success.

Zhang Gong, Director of the Future Network Theory Laboratory under Huawei's 2012 Laboratories, said, "It will be important for future networks to adopt an application-driven architecture. The end-to-end communication model must be defined based on applications' characteristics and experience requirements. Ideas and achievements shared by professors at this forum are closely relevant to the ADN concept."

He added, "There are three key design principles for the ADN architecture. First is service abstraction, which is crucial to creating information consumption models for different applications. Second is resource virtualization, which supports resource separation for services and network reuse. Third is smart control, which supports flexible scalability and rapid rollout in sync with service changes."

Hosted by Huawei, the First Future Network ADN Forum featured speeches by many experts, including Professor John. C. S. Lui, Chinese University of Hong Kong; Professor Jon Crowcroft, Cambridge University; Professor Don Towsley, University of Massachusetts; Professor Zhang Zhili, University of Minnesota; Professor Zhang Beichuan, University of Arizona; and Professor K. K. Ramakrishnan, University of California, Riverside.

Additional speeches were given by: Professor Chen Kai, Hong Kong University of Science and Technology; Professor Liu Bin, Tsinghua University; Professor Hu Chengchen, Xi'an Jiaotong University; Professor Richard Ma, National University of Singapore; Tan Kun, senior researcher at Microsoft Research; and Professor Qi Yaxuan, CEO of Yunshan Networks.

These experts shared their insights into the ADN vision, theories, architectures, key technologies (such as, network programming, control and measurement), business models, and applications for typical scenarios.

The open, lively discussions at the forum aimed to improve research into future networks and accelerate the implementation of ADN concepts. Open collaboration among universities, enterprises, and standards organization is the only way to achieve shared success.
