+ 0 Votes TCP/IP does not work that way robo_dev 2 years ago Network traffic has to take one defined route from the source to the destination. (provided the destination is not a router, but I digress)While it's possible on the LAN side of the fence to bond or bridge multiple interfaces, over the Internet, a data stream initiated by a particular IP address (e.g. that of your USB data card) must return through the very same interface, it cannot be split or combined. TCP/IP has only one defined route at a time, so a YouTube stream started by your web browser on your PC at a particular IP address can only flow back to your PC at the IP address that started it. While you can, with something like a enterprise Cisco router, have an interface failover to a second interface, and you could redirect certain traffic to a particular interface (e.g. FTP protocol file transfer to only go through a particular interface or round-robin DNS to a less busy web server), streaming over the Internet is very single-routed affair. + 0 Votes Reponse To Answer aldes 2 years ago Thanks!
