RINA

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, …
