History Posted the OCP Plugin project on 12/30/2015 Development started in May 2015 Needed by the Software Defined RRH research project at Foxconn Advanced Communication Academy (FACA) Foxconn has developed a lot of the code for the OCP Plugin This project is to continue and complete the work started by Foxconn

Motivation SD-RRH Framework Joint RRH and fronthaul network (T-SDN) provisioning in C-RAN

Goals Allow ODL applications (plugins) access to OCP stack Use Yang Models to represent RE Resource Model Provides a consists, well defined, method for interacting with RRHs using OCP (REST API, RPCs, DB Storage) Use MD-SAL architecture

Architecture Inspired by Openflow Plugin/Openflow Protocol Library projects and heavily leveraged their design and source code SW Components: OCP Plugin Southbound ODL plugin OCP Protocol Library Implements OCP Protocol OCP Service Northbound sample application which demonstrates OCP elementary functions

Message Flow Device Management Health Check BBU ODL RRH OCP Service OCP Plugin/Library RRH

Scope OCP v4.1.1 support Integration of OCP protocol library Simple API invoked as a RPC Simple API that allows applications to perform OCP elementary functions Indication processing Logging AISG/Iuant interface message tunnelling ALD connection management

Dependencies No dependencies on other projects

Emergence of C-RAN

CPRI (Common Public Radio Interface)

OCP (ORI C&M Protocol) The OCP layer is transported over a TCP/IP connection established between the RE and the REC OCP provides the following functions: Control & Management of the RE by the REC Transport of AISG/3GPP Iuant Layer 7 messages and alarms between REC and RE
