Too bad you can't use LAN to work from home

• qtzfz 4y ago
  You use VPNs with more or less the same result.

  Well, every WAN is a LAN when looked from a sufficient distance. DSL & Cable encapsulates Ethernet. City-wide networks are again Ethernet. In fact, everything is Ethernet with some routers between. So, you're actually using a mixed-carrier Enthernet LAN with a couple of NATs in the way. You can build another LAN on your LAN with VPN, too.

    I know you can use ethernet to build a network but if you build a global network with 90s technology, you'll get what?... the internet like we know today but worse. What problem was solved? That was my point responding to OP. We actually progressed and we are facing new challenges.
    • bayindirh 4y ago
      We're still using 90s technology. We only have faster switches, quicker routers, a couple of standards for faster connections, and some tools which disguise or repurpose deep packet inspection as "software defined networking". A country wide router still can stay in service for a decade. Residential FTTx installations consist of a TelCo class switch, maybe a router, compact DSLAMs if you have DSL service and a couple of fibers in, tens of fibers out for FTTH customers. It's faster hardware on the same stack. Nothing more, nothing less. ...and, oh, link-speed (transparent) DPI equipment in key places for lawful interception.

        It's electrified rocks all the way down.

        Theoretically, if an entire major city's connection with the outside world was cut off, could all the infrastructure within the city function as a really big city-wide LAN?
        • bayindirh 4y ago
          Yes. You might need a dhcpd on a laptop though, if your city's IP management is outside the said city (Cable/DSL modems needs their own IPs, unless they are static). ...and possibly a small DNS server (or a hosts file somewhere easy to get). That's all you need. If you want to navigate via IPs only, you can do with a DHCPd.

  > Too bad you can't use LAN to work from home Depends on what you consider "work from home". You might not be able to chat with your co-workers without a WAN connection (unless you go really old-school and use a telephone), but you can for instance develop software from home without any working network connection (and git makes it easier by allowing you to create commits while offline; see also the "git bundle" subcommand). I've done so occasionally when the Internet connection goes kaputt.

    That's kinda my point replying to OP. We've indeed progressed. I'm not sure if you are denying that?
