The Path Forward for Software Defined Networks
2
OpenFlow SDN is simple and elegant
3
What’s the Business Value in Openflow/SDN
Independent Software Vendors
provide Virtual Appliances on
standard high volume servers and
storage
Today’s network is a fragmented mix of proprietary
software and hardware appliances
High touch, low service velocity and slow to deploy
High cost of development is stifling innovation and
emergence of new vendors
Open interface standardized forwarding
planes provide commonality, scale and
capex/opex efficiencies – zero touch
provisioning
Design, deployment, management and
service velocity all benefit from a
common approach
Firewalls
WAN Optimization
Load Balancers
Service Aggregation
DPI
DDoS, Attack Mitigation
Session Border Controllers
Routers/Switches
4
The Scale Dilemma
Price $
Performance
Why do I need this
if this is sufficient?
5
And no, you can‘t do this
Price $
Performance
6
The concept is still simple and elegant
7
Reality is a little uglier
And then a
miracle
occurs
8
SDN in the WAN needs this
Price $
Performance

• OpenFlow 1.3 support, with a path to 1.5 and beyond
• Support for any compliant controller
• 100’s of thousands to Millions of flow entries
• Multiple Flow Tables
• Group Tables
• Thousands of flow updates per second
• Reconfigurable for TTP demands
What makes a good forwarding plane
10
The Corsa Data Planes
•4 X 40G QSFP+ Ports
•48 X 10G SFP+ Ports
• 4 X 100G CFP Ports
•24 X 10G SFP+ Ports
Corsa DP6420
Programmable Openflow 1.3 Forwarding Engine
•640Gb/s fabric capacity
•Multiple flow tables supporting millions of flow entries
•Fast table set up – 1000’s of flowmod updates per second
•Works with any OF1.3 compliant controller: ONOS, VellOS, Opendaylight, Ryu ...
•FPGA based to evolve with market, standard and use cases
Corsa DP6440
11
Solving real performance problems
BGP Gateway using
ON Lab ONOS at
ESnet
12
Bandwidth on demand in the WAN
L3 ACL Bandwidth Brokering under
VellOS 7.0 Connectivity Exchange
with OpenFlow 1.3 control
13
Upcoming trends
2009 20142013 20162015
Incubation, OF1.0 thru 1.X releases,
controller wars begin
OpenFlow 1.3
released
TTP Development and
controller/data plane
interoperability testing
Commercial grade controllers
from HP, NEC, Opendaylight ...
Commercial grade applications and
systems for WAN/Enterprise/Telco
Network Appliance vendors transition to
become Network Application vendors
No commercial grade
data plane or controller
= no commercial success
2017
Trough of
Disillusionment
Peak of Inflated
Expectations
Plateau of Productivity
Slope of Enlightenment

The Path Forward for Software Defined Networks

  • 3. confidential The Path Forward for Software Defined Networks
  • 4. 2 OpenFlow SDN is simple and elegant
  • 5. 3 What’s the Business Value in Openflow/SDN Independent Software Vendors provide Virtual Appliances on standard high volume servers and storage Today’s network is a fragmented mix of proprietary software and hardware appliances High touch, low service velocity and slow to deploy High cost of development is stifling innovation and emergence of new vendors Open interface standardized forwarding planes provide commonality, scale and capex/opex efficiencies – zero touch provisioning Design, deployment, management and service velocity all benefit from a common approach Firewalls WAN Optimization Load Balancers Service Aggregation DPI DDoS, Attack Mitigation Session Border Controllers Routers/Switches
  • 6. 4 The Scale Dilemma Price $ Performance Why do I need this if this is sufficient?
  • 7. 5 And no, you can‘t do this Price $ Performance
  • 8. 6 The concept is still simple and elegant
  • 9. 7 Reality is a little uglier And then a miracle occurs
  • 10. 8 SDN in the WAN needs this Price $ Performance
  • 11. 9 • OpenFlow 1.3 support, with a path to 1.5 and beyond • Support for any compliant controller • 100’s of thousands to Millions of flow entries • Multiple Flow Tables • Group Tables • Thousands of flow updates per second • Reconfigurable for TTP demands What makes a good forwarding plane
  • 12. 10 The Corsa Data Planes •4 X 40G QSFP+ Ports •48 X 10G SFP+ Ports • 4 X 100G CFP Ports •24 X 10G SFP+ Ports Corsa DP6420 Programmable Openflow 1.3 Forwarding Engine •640Gb/s fabric capacity •Multiple flow tables supporting millions of flow entries •Fast table set up – 1000’s of flowmod updates per second •Works with any OF1.3 compliant controller: ONOS, VellOS, Opendaylight, Ryu ... •FPGA based to evolve with market, standard and use cases Corsa DP6440
  • 13. 11 Solving real performance problems BGP Gateway using ON Lab ONOS at ESnet
  • 14. 12 Bandwidth on demand in the WAN L3 ACL Bandwidth Brokering under VellOS 7.0 Connectivity Exchange with OpenFlow 1.3 control
  • 15. 13 Upcoming trends 2009 20142013 20162015 Incubation, OF1.0 thru 1.X releases, controller wars begin OpenFlow 1.3 released TTP Development and controller/data plane interoperability testing Commercial grade controllers from HP, NEC, Opendaylight ... Commercial grade applications and systems for WAN/Enterprise/Telco Network Appliance vendors transition to become Network Application vendors No commercial grade data plane or controller = no commercial success 2017 Trough of Disillusionment Peak of Inflated Expectations Plateau of Productivity Slope of Enlightenment
