Abstract

   This memo specifies an unified radio and optical control architecture
   based on Software Defined Networking (SDN).  The architecture is
   designed for the purposes of end-to-end 5G Radio Access Networks
   (RAN) service, which enables joint radio and optical network resoures
   orchestration.  Based on this architecture, some new applications
   could be achieved, such as enhanced Coordinated MultiPoint (eCoMP)
   service, Baseband Unit (BBU) aggregation, fronthaul traffic
   prediction and so on.

1.  Introduction

   This memo introduces an unified radio and optical network control
   architecture based on the Software-Defined Networking (SDN).  The
   architecture consists of three planes: application plane, control
   plane, and data plane.  For data plane, each physical node of radio
   and optical networks (i.e., BBU, RRU, and optical transport node) is
   attached with an OpenFlow agent (OF-Agent) that communicates with the
   OpenFlow controller through the extended OpenFlow protocols (OFP).
   For the control plane, it realizes the control of the physical
   devises,such as configuration of optical/radio network nodes and the
   information collection of network statuses.  In addition, the control
   plane realizes radio and optical resources virtualization, and
   performs joint resourses allocation (orchestration).The application
   plane consists of various services, and each service injects a policy
   rule to the control plane for orchestrating radio and optical
   resources.
