Do We have the Backbone to Support Emerging Technologies ?Software Defined Networking

March 2017IRSE Australasia – Technical Meeting & AGM Sydney

Take-Away from this Presentation The Backbone Transmission Network is the Foundation on which

emerging technologies are built upon.

Without a solid Foundation, a building cannot become a skyscraper.

Software Defined Networking is the Foundation on which railways can grow into integrated transportation systems.

Software Defined Networking (SDN) is not a technological advancement, it is merely a new way of implementing functionality with existing proven technologies.

March 2017Do We have the Backbone to Support Emerging Technologies ?

Current and Future State of Backbone Communication Networks in Railways


PDH? Ethernet? MPLS?

Future State of Backbone Communication in Railways Dependence on hardware-based

networking solution. Do we need a new box each time

a new technology emerges and at what OPEX and CAPEX costs?


Change Management on the Railways


Coping with Short Product Lifecycles


Supply Chain & Globalization


Software based Solution is the Answer What if everything the mystery box is expected to do could be

configured in Software while generic white-boxes exist in the field?


SDN vs. Traditional Network Appliance


Replacing the Control Plane with a Computer running software


The Future of Innovation in Railways


Parallel Networks Not the Ideal Solution


Case study: East Japan Railway Company (JR-East) The Challenge The Solution & Results

JR-East: The Challenge


JR East: The Solution & Results


Provision of Service with SDN


The End of Serial Protocols on the Railway as We know it

SDN can be configured to analyse and process any serial protocol as it is software configurable.

Allows the departure from proprietary protocol and hardware.

Avoid solutions which lock an operator to a single vendor.


Fitting it all in the World of Railways and CENELEC

Tailored to support both Vital Safety system and Non-Vital system within a common platform.

Tools grant user greater visibility and control. EN 50128 processes can be applied to nominate a SIL

rating.


Business Drivers for SDN – Railway Applications

Easier to manage change & provision of services. No Vendor Lock-in. Streamline cost when up-skilling staff. Better Network Management – Agile and Responsive

Networking. Ability to cater for different types of traffic on a common

platform. Ability to apply railway RAMS in the networking software. Improved Network Security.


SDN Open Protocol

OpenFlow is an open protocol Open protocol does not mean 100% free The Market is now opened to not just hardware

manufacturers but also to software developers.


SDN in Railways – Where to From Here? Developing specific SDN

software that follows the process for SIL rating to pave the road for transitioning to Communication Based Train Control

Evolution of SDN-R……. Moving forward from GSM-R and LTE-R
