Multipath Service Type

The multipath service type determines whether multipath TCP should be attempted and the conditions for creating and switching between subflows. Using these service types requires the appropriate entitlement. Any connection attempt will fail if the process does not have the required entitlement.

Available options are:

• .none - The default service type indicating that Multipath TCP should not be used.
• .handover - A Multipath TCP service that provides seamless handover between Wi-Fi and cellular in order to preserve the connection.
• .interactive - A service whereby Multipath TCP attempts to use the lowest-latency interface.
• .aggregate - A service that aggregates the capacities of other Multipath options in an attempt to increase throughput and minimize latency.

Cleanup

• Remove forgotten debug code.

Logging & Metrics

This version of Atom adds the ability to log all network requests to the Console app as well as export all logs to a file.

To take advantage of this new feature, set log property on Atom instance to .on:

let atom: Atom = {
    let atom = Atom()
    atom.log = .on

    return atom
}()

Current implementation uses os_log.

If you choose to use the Console app for monitoring outgoing requests, you can use the following categories and subsystems to filter results.

Categories: Network, Authentication.
Subsystems: Your App’s Bundle Identifier.
