The ifup@.service is triggered by a udev rule and responsible to handle allow-hotplug interfaces. It basically works the same as in wheezy. The difference is, that in wheezy, the udev rule  called ifup directly, under systemd it calls ifup@<interface>.service, and this service does nothing else then run ifup <interface>. This has the benefit, that systemd can track it properly.
