Another company using whitebox switch instead of costly Internet edge routers through careful design and thought. Key realisation for Internet edge, you don’t need the entire public routing table, just a small part of it.
Slimming down the Internet routing table: “Most organisations, Redpill Linpro included, have dealt with this problem by throwing money at it. They go to vendors such as Cisco Systems or Juniper Networks and buy their routers. Those are purpose-built to be able to perform high-speed routing forwarding of network traffic even if the routing table should grow past a million routes. They make some truly terrific boxes, but make no mistake, they certainly do not come cheap. We would therefore like to see if there was a smarter and more cost-effective way of dealing with this problem going forward.
