David Ward's keynote from JavaOne 2011 on how networks are now programmable & intuitive, allowing application developers to access real-time data, geo-loc, and more information from the network through APIs and new protocols.

4. Beyond ferreting the information
Current approximation techniques are barely sufficient and inefficient
APPLICATION WORLD: GUESSING NETWORK WORLD: DERIVING
Applications blindly probe the Networks spy on traffic to try
network to understand what it to understand applications
can deliver

Bringing together the important elements … … enabled via real-time interaction to
influence the experience of the end user

19. Tune in - turn on: Be “in the topology”
Weak architecture = one-legged tap dancing Continuous, real-time streaming of surrounding
content, resources, places, people
And this is
Where am I? I am here! You’re here! around you:

§ Game

“Above the topology”
“Visualize the topology” “In the topology”
“Below the topology”
