Next 20 mins...

Some academic(s) arrive to tell us that (once again) they have Fixed the Internet, and (once again) it runs on top of the current actually-working internet, and (once again) if you sign up you can communicate with as many as twelve other computers.

Overlay over IP Simplify deployment Scalable Existing Tools

Router: NFD Link State Routing: NLSR Dynamic route updates on static network Connectivity: FCH Find closest hub/gateway

Overlay over TCP / UDP

Processing Overhead

17

Subtract network roundtrip time: 0.174ms

Testing notes

Performance severely degrades with 50000+ cached / in-flight requests

Necessary Configuration

37

Discovery Server

  • Write down its address / Give it a preconfigured address

Load Balancer

  • Address of Discovery Server
  • Write down its address / Give it a preconfigured address

Caching Server

  • Address of Load Balancer

Proof of Concept Performance

Scraping state of router through CLI (on a timer) TCP connections propagate routes and updates Coarse grained partitioning of routes

slide-41
SLIDE 41

Does it work?

41

Reuse existing router in a load balancing configuration Minimal configuration, self connecting network

Lessons Learned

Now

Rapidly evolving research testbed for new ideas Things break or are not optimized

Future Some new network based

  • n these ideas

Or maybe not (IPv6…)
