A couple links that might help:

- [Ziti Mobile Edge (iOS) - #12 by scareything](https://openziti.discourse.group/t/ziti-mobile-edge-ios/2291/12) In the diagram in this post, @scareything covers the TCP interaction (SYN -\> SYN/ACK) between a host and tunneler ("Ziti Mobile Edge" and ziti-edge-tunnel as the tunneler in the sequence diagram)
- [Connection Security | OpenZiti](https://openziti.io/docs/learn/core-concepts/security/connection-security) The top two diagrams cover the independent mTLS links and the end-to-end encryption added by the app endpoints (meaning, "apps that include a Ziti SDK, such as any of the tunnelers")
- [Data Flow Explainer | OpenZiti](https://openziti.io/docs/guides/data-flow-explainer) include high level data flow among controller, routers, and SDK endpoints (such as the tunnelers).

@scareything will be able to go deeper on the host/tunneler interactions, but I believe he's out-of-pocket for the next few day.
