TSN mcrc calculation wrong

1

I am enhancing and developing simulations with Frame Preemption and noticed that Wireshark flags mismatched checksums for SMD-C values that are not the final fragment of the packet. You can...

When clocks diverge too much, packet sources might schedule packets into the past, resulting in error

1

When clocks diverge too much, it results in this error: `Cannot schedule message (inet::ClockEvent)ProductionTimer to the past, t=0.0469998 -- in module (inet::queueing::ActivePacketSource) ClockDriftShowcase.source2.app[0].source (id=208), at t=0.047s, event #142502` For reproduction:...

There are several affected modules: EthernetMacPhy, EthernetCsmaMacPhy, Ppp, PacketTransmitter/PacketReceiver, etc. The NetworkInterface module already contains code to compute the desired datarate from both module parameter and channel parameter.

The signal decoding also happens in the wrong bandwidth including the guard subcarriers which do not carry information at all. For example, a 20MHz signal only carries information in a...

Possible memory issue when registering custom protocols

1

Hello! I have encountered a problem when defining a custom `inet::Protocol` (within a new project referencing INET) and registering it to `IpProtocolGroup` via the `ProtocolGroup::addProtocol()` method. A memory corruption occurs...

Possible incorrect calculation of residenceTime in gPTP

3

While the gPTP code seems to correctly work and keep the clock in sync, the calculation of `residenceTime` is not clear. The time correction value is calculated as the newTime...

osgEarth is hard to get, so it would be great to use the https://geographiclib.sourceforge.io/ for geo -> carthesian conversion.

Integrating the Application layer with VLAN layer

10

From the [documentation](https://doc.omnetpp.org/inet/api-4.4.0/neddoc/inet.linklayer.ieee8021q.Ieee8021qProtocol.html), it looks like the `socketCommandProcessor`, `SocketPacketProcessor`, and `SocketTable` modules can be enabled in order to allow the application layer to directly set VLAN tags. However, the documentation...
