  • Is it even possible to have a redundant internet connection and desktop at home?

    @elmer: The premise stays the same though - so you realize it's now a war zone might decide to use 2 different satellite based ISPs - if you had those already configured, it would just be a matter of disabling other network connections and have communication transparently move to the satellite based usb sticks (or maybe they'd need rj45 so you'd have some adapter for that).

    What the physical network medium is should not matter here as all the redundancy features are implemented in software abstraction layer. USB adapters or dock with different type of wireless connections (perhaps a dock would have antenna connectors instead of fixed antennas).

     

  • Is it even possible to have a redundant internet connection and desktop at home?

    The smartphone thing was just about using the smartphone as your lte/wifi usb stick incase you lost your lte+wifi usb stick (which you were using for purpose of having adjustable antenna location & orientation as that I find is very significant when it comes to perf, just like you point those dishes at the satellite - I've used wifi as my primary internet for 5 years now and the only problem with it is that the wifi sticks tend to not last very long before developing intermittent problems not related to the antenna- I believe it's because they heat up and there's some caps that go bad - can't think of any other explanation why they fail so frequently - except if the firmware has a time bomb built in! - other theory is that certain type of loading is more stressful for the caps but again haven't seen anything confirming this theory - it's just odd how easily these $10 wifi sticks keep failing, I bought a whole bunch in anticipation of it.... I use them as 24/7 constantly active primary connection, nowhere it says they aren't good for serious use so why not).

  • Is it even possible to have a redundant internet connection and desktop at home?

    So does Windows VPN client support that kind of multi-homed simultaneous access?

  • Is it even possible to have a redundant internet connection and desktop at home?

    Hmm I actually think that this can be (for now) achieved with VPN if you only need the 'same IP' for a particular service (though you could have clever cloud VPN service that decides the VPN exit node based on what IP you are trying to reach over VPN in order to maximize performance for any servers accessed over vpn while maintaining same IP across the exit nodes). You then just need to verify that your VPN client supports having simultaneous connections over multiple homes (lte+wifi+cable) with different IP to same VPN server. So the VPN client then manages the failover and deciding what packets to route over which home (eg. maybe high bandwidth&latency satellite and low bandwidth and low latency mobile).

    The VPN server could be hosted in a cloud nearby the service you need redundant access to so that takes care of the redundancy there.

  • Is it even possible to have a redundant internet connection and desktop at home?

    This kind of brings to mind some sort of 'global isp of isps' that sets up the ASN/BGP etc so that their customers get the redudants service using multiple isps at any place in the world.

    So lets say such existed, what if anything is missing from Windows to implement it and how would you do it if it existed now?

  • Is it even possible to have a redundant internet connection and desktop at home?

    Sounds like I may need to explain why other than server/cloud providers need redundant glitch free multi-home failover etc.

    The "home" here is a flexible term.

    eg. One might be using airbnb or similar service to relocate the "home" location frequently, while having a global prospecting/consulting type of gig and to manage their other previous biz could use redundant (lte+wifi or lte+cable) connection at every location.

    There are "monitoring jobs" where it's essential that while you are "on the job" the "control room" has "lights working"... eg. lets say you were remotely monitoring nuclear facilities few hours a day while doing a global consulting gig living in other peoples homes and perhaps the monitoring software didn't allow logging in from 2 ip's at same time but you didn't want to miss any events. 

    One might be walking around on some holiday in remote country that suddenly became a war zone and where one became the 'reporter' of local events. I should be able to patch the video stream from my smartphone reliably using "ISP of ISPs" that allowed my smartphone to have connections to all local ISPs on any country and satellites/drone ISP too if nothing else available - preference going to lowest latency or highest bandwidth connection depending on statistical analysis of the packets (the blog.ip.fi guy said that most full MTU size packets tend to be high bw data while smaller tend to be things needing low latency).

     

     

  • Is it even possible to have a redundant internet connection and desktop at home?

    Google for redundant mobile internet came across this:

    http://fkdv.se/mobileinternet-part2/

    Way too heavy weight solution and completely pointless to have such large system when you practically can get exactly same result with 2 smartphones if you could somehow get a single IP across the smartphones to your laptop... Then you'd have battery backing in both the "router" (smartphone) and the computer. The reason I don't like this that much is that you end up eating up the phone battery just to route packets to the laptop, but it might be a decent backup incase your usb wifi+lte stick fails.

     

    Optimal solution seems to be to have LTE+wifi in the laptop and then another lte+wifi through USB (perhaps also incorporating a shared battery for powering the laptop in single hybrid device - very portable mobile dock kinda)... this way if one antenna gets blocked, you still have another. Then just have 2 laptops and the replicated virtual desktop (using very fast wifi for short distance).

     

  • Is it even possible to have a redundant internet connection and desktop at home?

    (quick google about BGP sounds like it's some sort of heavy protocol - maybe there needs to be some way developed to get a single IP across different ISPs using 2 decicated usb wifi+LTE hybrid sticks)

    That is still one box and one power supply. I'm talking about 100% redundant system and preferably mobile one. Probably the most solid solution is 2 laptops (due to each having own battery) and software BGP with 2 ISP's over multiple wireless connections - while you might want a well cooled usb wifi with external antenna connector - it doesn't really matter if the redundancy is solidly implemented such that transient failures of the usb wifi sticks only get registered in 'action center as to-do maintenance items' but do not affect performance.

    This solves the problems you get with routers which are:

    - software that might stop updating once router vendor deems product 'legacy'

    - reliance on single power supply (secondary caps in tight space near the parts that heat up - built in time bomb)

    - no battery backed power

    - who wants to lug business routers around if they want redundant connections while mobile?

    - nothing in the router box that cannot be run on idle core without loading system up too much, it's just less powerful computer that is less guaranteed to receive upgrades.

    - with software BGP support you should be able to get the single IP across two wireless usb sticks connecting to different operators - this might be doable without BGP but I haven't yet heard how ...

    - BGP may have problems in customer (possible attacker) facing scenario but I can't really tell, it just sounds like something the author of this blog is concerned about: http://blog.ip.fi/

     

  • Is it even possible to have a redundant internet connection and desktop at home?

    So lets say you have 2 ISP's offering internet to your home. Then you have 2 computers with 2 ethernet ports each, and cables from both computers to each 'router' or whatever. (or maybe 2 wireless adapters on each computer connecting to 2 different wifi routers of different brands)

    Then each computer is running some sort of virtual desktop that ensures that if something fails in one computer, exact same desktop state is replicated on the other computer so that you don't have to stop what you are doing just because something fails.

    While using 2 ISP's you should still have a single IP on both computers so that no application knows if something failed (well, besides failure monitoring apps).

     

    I read something about BGP being used for this? So how do you set that up as a consumer? Does Windows 10 support it for this scenario?
