What does an Automotive Plant Have in Common with a Data Center?

Answer #2…they have functions that manage and control the flow of data are somewhat similar!

So what is all this about? 

Software Defined Network controllers focus on controlling the flow of data across a network in a standard and programmatic way.



PLCs control movement of devices and thus product through a manufacturing system in a standard and programmatic way.



An SDN Controller is like a PLC.



A switch or router is like an I/O block.

What does an Automotive Plant Have in Common with a Data Center? Their Ethernet networks all share the following embedded in all network devices Management Plane

• Monitoring • Remediation

Control Plane

• Behavior • Characteristics

Data Plane

• Message transport

Traditionally each network device must be “touched” to configure and manage these planes - with the Control Plane being touched the most – creating complexity

SDN Standards Today 

OpenDaylight: open source controller



OpenFlow: open source protocol/API



Both are current communities providing standards for Software Defined Networks



Both are open and may be used together



Overlapping vendor support



Data center focused



Underlying hardware provides performance differentiation only; throughput etc.

No thought to the industrial space General Session and Annual Meeting of Members © 2014 ODVA, Inc.

Can ODVA Bring SDN Concepts to Industrial Automation? 

CIP and EtherNet/IP can be used to create a an Industrial Network Controller for the automation network infrastructure.



This Controller can be used to operate switches and routers as we do I/O today.



CIP can be extended to communicate with the network infrastructure devices with new attributes.
