There are several things that make this difficult. Much of the difficulty relates to the device changing it's network address. Seamless transition requires that the application can:
- Find the new address; i.e. Cell provider vs. Residential/Business ISP
- Associate the new address with the same flow
- Duplicate packets and reassemble them, or change to "better" path interface.
- londons_explore 3y agoOn both android and iOS, a regular app can't choose to send packets over both 5G and wifi at the same time. Thats needed to setup a new connection while still using the old one.
- toast0 3y agoI was pretty sure that android and iOS both have apis for apps to choose between 'whatever is best', 'wifi preferred' and 'cellular preferred'? I don't know the details, but some iOS network apis (Network Kit?) allow you to set a required interface type somehow. https://developer.apple.com/documentation/network/nwparameters/2998706-requiredinterfacetype https://developer.apple.com/documentation/network/nwparamete...
