OPEN SOURCE NETWORKING • The Linux Foundation • Foster innovation across the entire open source networking ecosystem. • Coordinate across multiple open source projects. • Initiatives and identify key areas for collaboration to create an open source networking stack.

OPEN SOURCE NETWORKING • You can build your solution from those open source projects. • For example. If you want to choose a software switch in your networking. • You can use one of the following open source project. • OpenvSwitch • FD.io • io.Visor • You can also integrate those with DPDK to support high performance.

OTHER EXAMPLE • An example from the Open Source Networking Day London • Combine some open source projects together • OpenStack • OpenDayLight • FD.io • OPNFV • ONAP • Reference: Open Source Networking Days

Before we talk about the SDN. Let we see the history of programmable network.

Reference:The Road to SDN: An Intellectual History of Programmable Networks

SDN HISTORY • Software-Defined Networking (SDN) • Stanford Professor Nick McKeown publish a paper in 2008. • OpenFlow: Enabling Innovation in Campus Networks • OpenFlow first version 1.0 in 2009 • Open Network Foundation (ONF) in 2011

SDN HISTORY • Google publish a paper related to SDN in 2013 • B4: Experience with a Globally-Deployed Software Defined WAN • How about Taiwan? • As I know, NCTU starts to study the SDN around 2012/2013. • We start to contribute to those SDN related open source projects from 2013 • Controller • Floodlight, Ryu,Trema, ONOS • Network Emulator • mininet

SDN • The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.

THE SDN ARCHITECTURE • Directly programmable • Agile • Centrally managed • Programmatically configured • Open standard-based and vendor-neutral

THE SDN ARCHITECTURE • Network control is directly programmable because it is decoupled from forwarding functions. Data Plane Switch Application Controller Control Plane Control Protocol Application Control Plane Data Plane Switch Cisco/Juniper/…

THE SDN ARCHITECTURE • Northbound API • Restful • gRPC Northbound API Southbound API • Southbound API • Openflow • OVSDB • SNMP • Netconf • P4 • …

ONF • Open Networking Foundation • Non-profit organization • For Menber • Led consortium driving transformation of network infrastructure. • Serves as the umbrella for a number of projects building solutions • Leveraging network disaggregation • White box economics • Open source software • Software defined standards

ONLAB • Open Networking Lab • Non-profit organization. (501 C3) • For Public • Build tools and platforms that enable and accelerate SDN and make them available through open source. • Educate the public on the benefits of SDN • Provide thought leadership to ensure continued innovation around SDN

WHAT IS ONOS? • Open Network Operating System (ONOS) • An open source SDN network operation system • SDN controller

CONTROL & DATA PLANE DISAGGREGATION

ONF ONOS BGP BMv2 ISIS Lisp Netconf OpenFlow OSPF OVSDB PCEP REST SNMP TL1

We have a SDN controller (ONOS) now. How can we use it in a real environment ?

CORD • Central Office Re-architected as a Data-center • It’s too complicated to explain the whole detail of CORD. • We just describe its architecture.
