Reimagining the future of routers

Re:Reimagining the future of routers by bogomipz on Wednesday June 08, 2016 @09:40AM (#11862188)

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.

Tomahawk is old and busted. Jericho is the new hotness.

Full tables in FIB.

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.
