Abstract

We present software defined access (SDA), an architecture for HetNets that incorporates various elements of SDN and software defined wireless networking (SDWN). SDA introduces a novel logical control path across radio interfaces and up to mobile devices. This control path allows SDA to regulate and configure data path via different RATs. Unlike SDN and SDWN, SDA can be deployed without changing network elements of RATs. The userspace implementation of client side utility is also presented to empower mobile devices with SDN-like flow management. This client with cloud hosted SDA servers presents an alternative for operator-independent and RAT-agnostic standalone SDA deployment. To demonstrate some of SDA's capabilities, we also present various testbed experimental measurement results.
