fromModule of packetArrived()

[ytrewq271828]

What does the fromModule argument in packetArrived() indicate?
I assume that this would be related to information regarding the sender process.
But I wasn't able to figure out what would be the exact value of the argument.
Is that the name of the sender process? Or something other than that?

Thanks in advance.

It is the name of sender element. In KENS, only "IPv4" is passed, so you can ignore the argument.

Then what about the second parameter &&packet?
Is it the incoming packet from network layer? Then how should we call packetArrived() when implementing handshakes?

Yes, upon packet arrivals, the packetArrived() method is called by KENS.

Then how should we call packetArrived() when implementing handshakes?

You can't. You only need to implement body of the method. To send packets, you should use sendPacket() method. See: https://github.com/ANLAB-KAIST/KENSv3/wiki/Tip:-Sending-and-Receiving-a-Packet
