Wow!

Wow!

• You are a member of a stellar group
• World-class talent
• Lots of great ideas
• Hard and important problems
• Stimulating hallway discussions
• Despite current funding climate, Im confident in
  our future
• That said

Raising the Bar

• What did I hear Randy say?
• We cant claim to be working on revolutionary
  architectures
• We are focused on incremental enhancements to
  the Internet architecture
• This is not the Randy I know -)
• Whitehouse advisor, DARPA PM, visionary,
  department chair, corporate director, creator of
  multi-billion dollar industries, future chancellor

Raising the Bar

• My feedback some simple themes
• Reject the IP service model
• Wonderfully elegant yet it doesnt work (really)
• Change the rules of the game
• Microsoft is wrong, Cisco is wrong, Oracle is
  wrong (okay, Apple is right)
• Its okay to think you may change the world in a
  big way
• Leave incrementalism to industry

4
The Problem

• The Internet service model is wrong
• No mechanism to enforce boundaries
• No mechanism for load-balancing and failover
• No mechanism for iBoxes
• Industrys response
• Lots of network-level hacks to solve important
  problems (NAT, load balancers, caches, firewall,
  etc)

5
The Opportunity

• Redefine the architecture
• Change the rules of the game so the hacks become
  elegant extensions of a superior architecture
• My gut instinct cant do this at the network
  layer (I.e., with iBoxes that process individual
  packets)
• Need to move up the stack

6
A Strawman Vision

• Do everything on the table as a transport level
  abstraction
• End hosts talks to infrastructure (over TCP)
• End hosts talk to each other over L4.5
• Two-level addressing (like I3)
• Next hop (I.e., iBox)
• End hosts
• Hop-by-hop transport embedded in network
• Routers forward packets between end hosts
  iBoxes
• iBoxes forward app payloads between end hosts

7
The Challenge

• This is really hard
• Change the end host OS
• (but maybe not the app)
• Change TCP
• Add a layer between TCP the app
• Convince the world
• Just a strawman
• Point is to think audaciously

Thanks

• Think big and revolutionary
• You can change the world
• Thanks
