BFD or Ethernet-OAM is the standard here. It can get a bit hardware dependant but getting You can get NIC's for computers (like most Nvidia/Meallanox or higher end Broadcom/Intel N…

This is due to advertising standards. They are required to advertise "average speed", although how this is actually calculated is nebulous. A&A not advertising can just say what th…

I once wrote something that did, as an internal tool. It was basically an MPLS traceroute tool that used LOC records on RFC1918 loopbacks to plot pretty maps (well, the lines were …

I've always thought we could put a bit of general purpose TCAM into general purpose computers instead of just routers and switches, and see what people can do with it. I know (T)CA…

True. But larger orgs don't buy "random laptops". The trick is to just buy laptops where you know everything works, and the company making them has a commitment to Linux. Buy your …

If you ever need a quick hack to get v4 connectivity over a true v6 only setup, you can use a public DNS64+NAT64 Gateway. You can find a list at https://nat64.net/public-providers …
