*Evolution of LSOAPI:
-Use case for model-driven - based Service Layer
-Review list of APIs generated by Service Layer YANG modules & identify the methods needed
* Brahmaputra release work items

Meeting Minutes

* Kevin reviewed the current LSOAPI - UNI Manager architecture then shared plans for using comprehensive MEF-compliant Service Layer and Resource Layer YANG models to create a new version of OpenDaylight UNI Manager plug-in for the OpenDaylight Boron release.
* APIs created by OpenDaylight YANGTOOLS from the MEF compliant Service Layer YANG model were shown for example.
* Kevin said the team is currently updating the LSOAPI - UNI Manager proof of concept/demo to show at CableLabs 2016 Winter Conference Feb. 10 - 12. Mufaddal shared a preliminary map application for the demo.
* LSOAPI code is checked in to the OPNFV LSOAPI project repository for the Brahmaputra release. We still need to complete some tasks for the code to be included in the release including running the code on a PHAROS installation, document a 'scenario' or test plan, and provide scripts for installing the LSOAPI run time environment.

*Status of LSOAPI for Brahmaputra release
*Next steps: MEF service level functionality in OpenDaylight

Meeting Minutes

Kevin reviewed the status of the OPNFV Brahmaputra release and provided a preview of the next steps for the LSOAPI project.

Code freeze for the OPNFV Brahmaputra release was yesterday. Code from this project (Connectivity Services LSO / LSOAPI) is in the project Git repository ready to be included in the release. The Brahmaputra release of OPNFV is scheduled to occur February 2. The LSOAPI code won’t be useful in the Brahmaputra release because LSOAPI calls the OpenDaylight UNI Manager plug-in, which won’t be in OpenDaylight until the Beryllium release, which is also scheduled for February. OPNFV Brahmaputra bundles the Opendaylight Lithium release (prior to Beryllium), so the UNI Manager plug-in won’t be in it. But at least the LSOAPI code will be a “foot in the door” in the OPNFV open source software.

The next step for the LSOAPI project is to create MEF service-level APIs derived from a Service Level YANG model. OpenDaylight’s ‘YANGTOOLS’ utility converts YANG modules to Configuration Data Tree and Operational Data Tree and ‘stub’ APIs. From this framework code can be added to handle service requests made to the data trees through the northbound application interface and pass the requests to the MEF Resource Layer which in turn configure network equipment appropriately.

Kevin shared via the web conference screen sharing utility the APIs created by OpenDaylight YANGTOOLS utility from a Service Level YANG model derived from MEF service layer specifications.

A lot of work remains to be done to create a working Service-level implementation, even a basic proof-of-concept, and the same for the Resource-level. To start with we need to define the initial use case, select which of the methods are required for the initial use case, define the architecture, and develop the Java “listener” code to handle the service requests.

Kevin issued again a call for participation. Intraway hopes to be able to provide development resources.

Kevin took the action to draft a use case for next week’s OPNFV LSOAPI project call.

LSOAPI Phase 2 scoping considerations - Part 2 October 1, 2015

Consensus About LSOAPI Scope from Meeting

In Scope for OPNFV Phase 2
* Map L2CP frames to a single class of service per EVC (per service)
* Map SOAM frame class of service ID-to-class of service name to mirror data frame class of service ID-to-class of service name (per MEF 10.3)
* Apply bandwidth profiles on a per-EVC basis, i.e., support single bandwidth flow per EVC
* Single bandwidth profile node per profile (no token sharing)

Defer to Later Phases
* Map class of service to L2CP protocols on a per-protocol basis, i.e., allow multiple classes of service per EVC.
* Multiple bandwidth flows per profile / token sharing
* Frame coloring


September 24, 2015


* Extension of project scope: MEF Class of Service and Bandwidth Profile requirements (discussion will continue next week)
* Work-in-progress YANG model for OpenDaylight UNI Manager plug-in (topic deferred)



Consensus About LSOAPI Scope from Meeting
In Scope for OPNFV Brahmaputra release:
* Ethernet Private Line for single-operator service
* EVPL is a 'nice to have' in the information model and APIs if time permits.
* VLAN support
* Preserve LAN packet priority tagging (PCP, DSCP) values between customer LANs
* Class of Service per EVC, including detailed CoS metrics and objectives
* Ingress Bandwidth Profile

Out of Scope for Brahmaputra release:
* E-LAN and E-Tree and multiple operator services are out of scope for Brahmaputra.
* Class of Service names per PCP/DSCP, i.e., multiple CoS Names per EVC
* Egress Bandwidth Profile. To be included in scope in later phases, when E-LAN is in scope.

Discussion to Continue
* Token sharing
* Multiple bandwidth profiles per EVC
* L2CP CoS

First Meeting: August 13, 2015


  • Agenda bashing
  • Welcome and introductions
  • Initial project overview
  • Outline objectives for project Requirements


The meeting began late because the GoToMeeting login was misplaced and we were unable to start the teleconference bridge. Eventually we started an alternative GoToMeeting bridge and held the meeting in the remaining time.

Kevin Luehrs presented a project overview for attendees. The project objective is to develop REST APIs that receive requests for creation of Carrier Ethernet service and expose capabilities of OpenDaylight to configure devices with User Network Interface (UNI) attributes and configure an Ethernet Virtual Connection (EVC) between UNIs. A new UNI Manager feature plug in for OpenDaylight will be developed as an OpenDaylight project. The UNI Manager feature plug in supports and provides services to the northbound Connectivity Services Manager API, EVC Manager API and Class of Service API. Working prototype API code has been posted to the LSOAPI repository and prototype UNI Manager feature plug-in code is ready to be posted to the UNI Manager repository in OpenDaylight when that repository is available.

An information model was developed to guide development of the APIs. The model was contributed to Metro Ethernet Forum and we expect it to be incorporated in the MEF Common Information Model which is under development within MEF.

Development of the APIs will continue as a collaboration within OPNFV.

Kevin Luehrs reviewed the preliminary version of the Connectivity Services LSO Requirements: LSOAPI Requirements

Meeting participants contributed to the list of Problem Statements. Since attendance was somewhat light, likely due to the late start, we will review the Requirements again next meeting. Subsequent to the meeting Feature Requirements were added and a Functional Requirements list was begun.
