• Open Source and Open Standards• MEF and the Third Network• LSO Hackathons• Summary

Agenda

Introduction: Open Source and Open Standards

Standards provide backbone of internet

and basis for interoperability

Traditional Role of Standards

Standards formed over

period of years

Standards formed over

period of years

H/W, S/W, products, and services built

on these standards

Interoperability achieved over course of next

few years

Open source software (OSS) dominates the InternetAgile development and deployment speeds innovation … innovation that NEEDS standardizationStill important to have consensus based standardsBut SDOs need to realize rapid OSS cycle time can create a market consensus to fill a standards void

New World Order

• Fuel industry transformation in networking, cloud, IoT, …

• Leverage a vast community• Innovate at very fast pace• Sometimes result in de facto

standard

Power of Open Source Software

• Some assembly required• New projects often start quickly, then

may slowly fade away• Fragments, each OSS project solves

20% of problem but cannot easily be used together

• Hidden gaps, missing functionality, lack of overall architecture

Complexity of Open Source

• Internet Engineering Task Force• Make the Internet work better• Founded in 1986• Networking protocols and software• No formal membership or fees• Produces RFCs

• E.g. TCP/IP, HTTP, TLS, …• Multi vendor interoperablity is key

• Global Deployment of Carrier Ethernet Networks Services

• Found in 2001

• 210 + member companies

• Service Orchestration

• Certification Programs

• Multi carrier interworking is key

Messaging 4Transport

• Reference implementation of LSO Presto API within OpenDaylight• Extend OpenDaylight Unimgr project to:1. Implement LSO Presto APIs over RESTCONF and NETCONF2. Provide interface activation framework that operates across multiple

activation drivers3. Provide multiple vendor specific activation driver implementations4. Deliver MEF Carrier Ethernet 2.0 (CE 2.0) services using

OpenDaylight and combination of physical/virtual network elements

MEF OpenCS Packet WAN Project

• Participants from Cisco, HPE, Amartus, Microsemi, Ericsson• Added support for Presto to OpenDaylight - UniMgr project

• Presto definition in form of UML model – MEF NRP project

• xmi2yang used to produce YANG model - ONF Eagle project • Generated code for Presto within OpenDaylight

• Started work on interface activation drivers for OpenDaylight to configure underlying network elements, e.g. Cisco IOS-XR, Microsemi, and others

Euro16 Hackathon

• Uncovered issues with:• NRP model, ONF Core Model• xmi2yang tool

• Code generation from YANG models generated from UML models NOT straightforward • Hand tailoring of YANG models and code

• Code contributed upstream into UniMgr

• Issues with models and tools being addressed in MEF and ONF

• Summary blogpost

Lessons Learned

• OpenDaylight and PNFs/VNFs• Re-implement parts of activation driver framework• Develop activation drivers per vendor• Experiment with exposing telemetry data via Presto API to

OpenLSO Analytics project• Work with Bandwidth Profile implementations by multiple

vendors

Projects - OpenCS Packet WAN

• MEF Legato YANG models exposed northbound using Cisco NSO

Projects - LSO Service Orchestration

1. Load existing Legato YANG models into NSO and expose northbound to OSS/BSS systems

2. Explore options for connecting NSO to OpenDaylight via Presto

3. Explore options for configuring network elements via NSO

Summary

• Speed and spirit of open source• Rigor and stability of open standards• Each has positive impact on the other• Running code validates evolving standards• Standards unify and guide open source

implementations

Combine Open Source and Standards

Open Source

• Be active, ask questions, learn about efforts around you• Don’t reinvent the wheel

• Reinvent = time wasted + community building opportunity lost

• Contribute upstream• Don’t fork it up
