Latency solution

[Bowers7]

Besides load balancing, is it illogical or none existant for two isp to cut latancy in half? Fail over increases reliability of connections and load balencing increases the size of data, but is there a way to make two isp to work together in cutting latency in half? I know at start it may not change according to the law of physics, but after the start both isp can exchange information. Exp: isp1 can start the ping first and isp2 would start after, from then on your device and the server would go back and forth exchanging information not of there own ping but the ping from the other isp.

The only way I could see this working is if both ISPs were tightly connected to each other and your traffic were specially set with VIP priority across both networks.

 

So physically and virtually it's possible but practically and within your capability I'd say you're SOL it's not going to happen.

As a general rule, latency is as low as you're going to get as like you said, its physics based.  The exception is that one ISP might have a quicker route to your destination than the other, in which case picking that ISP would technically mean lower latency.

The big problem is, you're never going to know which ISP is best for any given destination.  So if one is consistently better than the other for a specific destination you use, then you could have a router policy that always uses that ISP for that destination (I actually have a rule on my router that sends traffic out a US VPN for a couple of websites that are geo blocked).  But in the real world, that's going to be a lot of effort and routing can change at any time, so there are no guarantees that the quickest ISP to where you want to go isn't suddenly the other ISP.
