- bifrost 6y agoI'm not sure which platform you're talking about, mine uses PPC, which hasn't been in a desktop in quite some time. kern.version: JUNOS 18.XXX.X #0: XXXX-XX-XX 03:28:10 UTC builder@svl-junos-p001:/volume/build/junos/18.X/release/18.XXX.X/obj/powerpc/junos/bsd/kernels/JUNIPER-PPC/kernel There certainly are some routers that use x86 based CPUs, but they're embedded versions which you'd be unlikely to use on a PC.
- job 6y agoYou can easily do origin validation on that type of CPU. It’s a very efficient lookup.
- bifrost 6y agoI guess we'll see what happens TBH. I didn't realize it'd been available in JunOS since 12.2 which covers a variety of devices (even some old stuff I've seen on customer sites), I've yet to come across a site with it deployed. Maybe I should do some consulting for folks.
- skissane 6y ago> mine uses PPC, which hasn't been in a desktop in quite some time Raptor sells desktops with IBM POWER9 CPUs – https://www.raptorcs.com/content/base/products.html https://www.raptorcs.com/content/base/products.html – they are expensive, and the same amount of money would buy you a much more powerful x86 system, but they exist.
- londons_explore 6y agoNothing stops you hooking up a regular PC to do route validation and run the BGP protocol and stuff, and load validated routes into any router you choose.
- bifrost 6y agoThere are lots of things stopping that... The first namely being that nobody is going to do that unless they have too much time on their hands and don't actually run a real network. "Just loading routes" into a router is not really that straightforward.
- londons_explore 6y agoIsn't that the entire idea behind the "software defined networking" craze?
- bifrost 6y agoThere's certainly an aspect to that, but generally no.
- az656 6y agoA lot of people, including very large companies are doing this in production. Using a route reflector/route server isn’t new, and it is very common.
- bifrost 6y agoDoing it right is not easy, and most people don't do it correctly nor do they know how to make it work all the time.
- Hikikomori 6y agoBig isp core and edge routers absolutely use large Xeon CPUs.
- bifrost 6y agoIf you count a single multicore 1.9Ghz CPU as a "Large Xeon" then you'd be right, otherwise thats incorrect.
- Hikikomori 6y ago8 cores in Cisco rsp880, released a few years ago so not that small back then.
- bifrost 6y agoTook me a minute to realize you were Job Snijders too lol. We both know there are still garbagey nets out there using ARM32, MIPS and who knows what else out there for control plane processing. Only the big guys are gonna upgrade to support this.
