4. Overview
Forget “Next Gen” Let’s Focus on “This Gen”
Conceptual

5. A Look Back

6. Digital Evolution Phase 1: Adopt Telephones are awesome!
Man! My job making sure people can use the telephone is awesome!
Heck ya they are! Let’s use the telephone all the time!

7. Digital Evolution Analog Telephone Switch Operator Phase 2: Scale
Manual Request and Action
Physical Capacity Limitation
Requires Duplication of Identical Effort
Prone to Error… see “Operator Error”

8. The Digital Lifecycle Phase 2: Scale
Nothing against telephone operators … but there has got to be a better way…
“It’s not the operators fault, we need to re-think the way we do this…”
“There’s no way we can expect any single person or group of people to manually route all of the world’s phone calls…”

9. The Digital Lifecycle Phase 3: Evolve We still need operators.
We still need physical infrastructure.

10. The Digital Lifecycle Phase 1: Adopt The Internet Is Super Cool!
Ya it is!
Ya it is!
The Internet Is Super Cool!
Ya it is!
Ya it is!
Our Job Making Sure People Can Use The Network Is Sweet!
Ya, Dude! Super Sweet!

11. The Digital Lifecycle Analog Telephone Switch Operator
Phase 2: Scale
Aaaaaaaah!

That list look familiar?

12. The Digital Lifecycle Don’t Be These Guys… Phase 2: Scale
Nothing against network engineers… but there has got to be a better way…
Don’t Be These Guys…

21. Why Do We Need It?

22. Why Do We Need It? Pilot Controls: Take-off/Landing Flight plan Course
Altitude
Speed
Aircraft Mechanics
Obstacle avoidance

23. Why Do We Need It? ATC Controls: Take-off/Landing Flight plan Course
Altitude
Speed
Pilot Controls:
Aircraft Mechanics
Obstacle avoidance
The need for Air Traffic Controllers?
Too many planes in the sky to let them all make their own decisions
We can have more aircraft in the sky at once if they’re more accurately orchestrated
Aircraft can’t see each other before it’s too late
Reactive flying isn’t acceptable when you have 500 passengers
Congestion avoidance

24. Why Do We Need It?
Too many application dependencies to keep track of manually
We can have more active traffic and applications if they’re more accurately orchestrated
Stability requires consistency
The need for agility mandates the need for automation
Automation requires programmatic responses to changing conditions
Reactive engineering isn’t acceptable when you have business critical applications
Dynamic congestion avoidance, prioritization and security policies

25. Why Do We Need It? Automation in general
Automation vs. Artificial Intelligence

26. Why Do We Need It? Automation vs. Artificial Intelligence
Just like a router, switch, or firewall – You need to tell the robot which block to move just like you need to tell the infrastructure how to treat traffic.

27. Why Do We Need It? Automation vs. Artificial Intelligence
In order to tell the robot which block to move, you need to know exactly where it is, where you want it moved and when.

28. Real World Use Cases That Matter Right Now
