Cut-through behaviour for the INET WirelessHost

Question

The .NET WirelessHost inherits from the StandardHost which has store-and-forward as its default forwarding behaviour. Is there a way to change that behaviour to cut-through? I did not find any fitting parameters in both the StandardHost and WirelessHost modules.

Answer 1

TL;DR: No, that is not possible and makes no sense.

1. cut-through is a layer 2 (link layer) device feature ie switches can support it. It is impossible to do this on layer 3 .network layer) as IP packets can be fragmented, defragmented and the IP header itself can change during routing. So at most, the question should be: can a wireless access point support cut-through? BUT:

2. cut-through implies that the interface can receive and send simultaneously. That's an almost impossible feat for a wireless transciever over a radio medium. (unless the transmission is highly directional (like. StarLink laser links, but in that case they could be considered as wired channels)
