where theory hits reality is when those whiteboxes and their routing-stacks encounter the 600K routes coming from 40 different exits. still no viable solution out there today- quagga, bird, any ?

>where theory hits reality is when those whiteboxes and their routing-stacks encounter the 600K routes coming from 40 different exits. still no viable solution out there today- quagga, bird, any ? Well handling the routes themselves can be offloaded to regular servers. The issue is indeed managing the forwarding tables. "Something something aggregation, non contiguous bitmasks, NDA" runs wildly for the door. :)

The IPv4 table today is about 610K routes. There shouldn't be a problem fitting the RIB, associated BGP communities and AS Path info in 32 Gigs of DDR 4 RAM. There are plenty of boards that will hold 750Mbs of RAM from the usual folks - DELL, HP and Supermicro. So why is there no viable option? Also this is a hardware concern. How does choice of open source solution - Vyatta, Qugga or Bird matter? What is the issue?

  The issue is that Tomahawk has far less than 610K entries of TCAM and a dozen different teams are exploring various types of RIB caching to accommodate that.

    Sorry, what is Tomahawk?

        Thanks for the link, but how does this relate to my comment asking comment asking why you can't build your own router with commodity hardware? Isn't the Tommahawk and Jericho intended for ODMs who are building traditional switches?

        It's pointless to use anything other than these ASICs because their price/performance is so far ahead. Software routing is especially pointless.

    Tomahawk is old and busted. Jericho is the new hotness. Full tables in FIB. https://www.broadcom.com/press/release.php?id=s902223 https://www.broadcom.com/press/release.php?id=s902223

      Shh! You're ruining it.

A new whitebox based on Jericho is your solution.
