A prototype of policy defined wireless access networks
Hung Nguyen, Thien Pham, Khanh Hoang, Duong Nguyen, Eric Parsonage · 2016
In the past few years, significant progress has been made in using software defined networking to increase automation, improve network security, simplify network configuration and reduce human effort to establish and maintain the network. There are now a vast number of studies exploring how to utilise policies to achieve the above goals. In this paper, we apply policy defined networking to wireless access network functions. We describe the details of our prototype policy defined networking solution that automatically translates high-level policies into device level implementations. We develop a novel metagraph model that can be used for policy specification, verification and refinement. We show that sophisticated traffic engineering policies can be implemented automatically on commodity hardware using our framework.
