2. 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

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

4. 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

5. Base Network Service Functions

Additional Virtual & Physical Devices
Data Plane Elements (Virtual Switches, Physical Device Interfaces)
VTN: Virtual Tenant Network
DOVE: Distributed Overlay Virtual Ethernet
DDoS: Distributed Denial Of Service
LISP: Locator/Identifier Separation Protocol
OVSDB: Open vSwitch DataBase Protocol
BGP: Border Gateway Protocol
PCEP: Path Computation Element Communication Protocol
SNMP: Simple Network Management Protocol

6. 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

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

8. 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

9. Dependencies
No dependencies on other projects

10. Project Details Project Lead (elected by Committers) – Richard Chien
Project Contact – Richard Chien
Test Contact – Richard Chien
Initial code contribution from Foxconn
Initial committers – 3 Foxconn

11. BACKUP SLIDES

12. Emergence of C-RAN

13. CPRI (Common Public Radio Interface)

14. 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

15. RE Resource Model
