3. IPC API
 APs communicate using a portId
 6 operations:
 int _registerApp(appName, List<difName>)
 portId _allocateFlow(destAppName, List<QoSParams>)
 int _write(portId, sdu)
 sdu _read(portId)
 int _deallocate(portId)
 int _unregisterApp(appName, List<difName>)
 QoSParams are defined in a technology-agnostic way
 Bandwidth-related, delay, jitter, in-order-delivery, loss rates, …
