A brief history - SDN origins 2006 - Clean Slate Program - Stanford, Berkeley, NSF First open source projects - Mininet, OVS ... Beginnings of Software Defined Networking (SDN) Created OpenFlow standard

2011 - Open Networking Foundation Non profit - advance SDN and OpenFlow for industry benefit

Open Networking Lab Non profit - Open Source network infrastructure development

for public benefit

2014 - Open Network Operating System (ONOS) launched 2016 - Central Office Rearchitected as a Data Center (CORD) launched Both are Linux Foundation Collaborative Projects

Partners

6 Leading service providers make solutions relevant to them 10 Leading vendors help make solutions real & ready for deployment

CORD Project

CORD Vision

•  Built around commodity servers and white-box switches, and to the extent possible, leverages merchant silicon.

•  Enables disaggregation, and is not restricted to running bundled legacy VNFs in virtual machines.

•  Leverages SDN to both interconnect the virtual and physical elements and as a source of innovative services.

•  Extensible platform that can be customized to include multiple access technologies and services.

•  Adopts best practices in building, composing, and operating scalable multi-tenant cloud services, including support for multi-tenancy.

Why Model Driven? Beyond Micro Services

Micro Service Arch •  Single Application – Single Trust Domain – Fixed Set of Services

•  Fixed Infrastructure – Virtualization Technology – Network Functionality

CORD’s Service Control Plane •  Multi-Tenant Platform – Mediate Trust Across Domains – Configurable Set of Services

•  Programmable Infrastructure – Multiple Virtualization Technologies – SDN Control Apps as Services

Model-Driven Design Models are the definitive specification of the architecture

Defines the abstract objects and the relationships among them Predicates (first order logic) defines actions on models

Architecture is “executed” to operationalize the system Represents the system’s authoritative state

Auto-generates all Northbound APIs Enforces security policies and engineering invariants

Activates the data plane (backend components)

Model-Driven Design Architecture evolves over time

On-board new models to extend the architecture Add invariants (predicates) to reflect experience

New user requirements (from operators)

New engineering constraints (from developers)
