Cover Slide 1 of 3

2. Problem Statement
Service providers’ Carrier Ethernet fulfillment processes are currently too labor intensive and not seamless across multiple vendors.
Not all equipment provides all needed functions, e.g., those defined by ITU Y.1731 ‘OAM functions and mechanisms for Ethernet based networks’.
Service providers currently need to deploy, configure and manage multiple devices in customer premises to provide business services.
Significant differences in how equipment is configured and managed.

3. OPNFV & OpenDaylight Projects Overview
Project goal: Investigate and identify means to facilitate fulfillment of Ethernet/connectivity services using virtualization technologies (SDN and NFV) and open source SDN controller.
Current objectives:
Develop information models and open standard APIs
Compliant with MEF-defined Carrier Ethernet Service
Enable applications to leverage OpenDaylight capabilities to configure network components and connections Initial use case: Ethernet Private Line service
We believe this work is consistent with MEF LSO vision

4. OPNFV & OpenDaylight Projects Overview
Advantages Provided by OpenDaylight
Provides SDN controller functionality enabling automation of device and connection configuration.
Provides multiple southbound protocols enabling control of devices from multiple manufacturers.
As an open source project ODL offers a community of developers and other skilled resources that can provide scale to API development and modifications as well as differing perspectives on solutions.

5. Virtualized Business CPE Software Prototype Services Architecture
Layered Architecture Consistent with MEF Lifecycle Service Orchestration Vision

6. Information Model for Ethernet Services
Based on MEF Specifications & Basis for APIs
EVC Class: Ethernet Virtual Connection service attributes
EVC Performance Class: EVC performance attributes
EVC Endpoint Class: EVC per UNI attributes
UNI Class: per UNI attributes
CoS Class: Class of Service attributes
Submitted as a Contribution to MetroEthernet Forum

7. EPL Provisioning Using ODL PoC
CableLabs API Poc and Validation/Demonstration Platform
Proof-of-concept implementing prototype APIs & ODL plug-in
Simple web UI emulating a user portal initiates EPL service
APIs call ODL to configure instances of Open vSwitch to behave as UNIs
APIs call ODL to configure GRE tunnel between the OVS to emulate EVC
When tunnel is created traffic passes between client laptops
Tunnel can be terminated from web UI

8. EPL Provisioning Using ODL PoC
Laptop/Ubuntu Linux
emulates cloud server
Laptop PCs
emulate client LAN
Raspberry Pis
emulate MEF Carrier Ethernet service UNIs (endpoints)

9. EPL Provisioning Using ODL PoC
Cable Labs
Scenario
Configure the Classes of Service
Specify the desired service (Ethernet Private Line) Select the service endpoints Select the Class of Service
Initiate service creation APIs trigger OpenDaylight to create UNIs APIs trigger OpenDaylight to create connection

10. EPL Provisioning Using ODL PoC
Initial State: Demo UI with Nothing Configured

11. EPL Provisioning Using ODL Demo
Initial State: Open vSwitch in Raspberry Pis Not Configured

12. EPL Provisioning Using ODL Demo
Initial State: OpenDaylight Operational Data Store Has No Endpoints (UNI)

13. EPL Provisioning Using ODL Demo
Initial State: No Traffic Passes Between Client LANs

14. EPL Provisioning Using ODL Demo
Configure Classes of Service and Create EPL

15. EPL Provisioning Using ODL Demo
Final State: Open vSwitch in Raspberry Pis Configured

16. EPL Provisioning Using ODL Demo
Final State: Endpoints Configured in OpenDaylight Operational Data Store

17. EPL Provisioning Using ODL Demo
Final State: UNI and EPL Attributes in UI

18. EPL Provisioning Using ODL PoC
Final State: Traffic Passes Between Client LANs via GRE Tunnel (Ethernet Virtual Circuit – EVC)

19. EPL Provisioning Using ODL Demo
Final State: List of REST Calls to APIs and to ODL

20. Proposal to OpenDaylight
New UNI Manager Feature Plug-in
Requirements for Ethernet services APIs and UNI Manager ODL plug-in to be clarified in OPNFV ‘Connectivity Services LSO’ requirements project
Prototype UNI Manager MD-SAL code based on minimum EPL Service YANG model will be contributed to ODL
Leverage full YANG model from MEF
Evolve UNI Manager ODL plug-in within OpenDaylight
