Re: [Taps] New Transport Networking APIs in iOS 12 beta

Hello Michael,

The architecture is designed specifically to allow loading different protocols. The parameters object is centered around a “protocol stack” configuration object, which is composed of protocol options for defined protocol implementations. This only exposes a default stack now, but is designed to offer the configuration of alternate stacks as well. In this first version, we’re only letting developers compose stacks with pre-defined protocols, but I want to allow custom protocol definitions and implementations going forward—for both simple framers, as well as full blown transports like SCTP and QUIC! The model of the connection sending and receiving messages is sufficiently generic to support any of the TAPS protocols. 

Best,
Tommy

This provides our basis for “post-sockets” API work. As we define as a working group more of the full TAPS API vision for protocol agility, we'd like on add that support to this framework.

Either way, we’d love for everyone to take a read through the API and give feedback on how we can continue to evolve things towards a post-sockets and fully TAPS model. Note that on iOS and tvOS, this framework is currently using a user-space networking stack instead of sockets when applicable.
