In fact this is not what STANAG 5066 Annex H "Implementation Guide and Notes" section suggests. According to this section and the tests held by DRA (Defence Research Agency), 1) The throughput is not strongly sensitive to frame size 2) 200 bytes is a good 'compromise' selection for frame size Besides, STANAG 5066 has the ability of doing DRC (Data Rate Change) in accordance with SNR values so what is suggested by that white paper, I think, is not applicable.
That's somewhat of an implementation detail that shouldn't affect code that tries to dissect those packets.
Precisely. Yet may be a little clarification is needed. You might have noticed that in my first e-mail I mentioned about DTS (Data Transfer Sublayer) and that one of our dissector methods has the name dissect_s5066dts() but now we are talking about MAC layer and all this may look like a confusion but it is not. As explained in Isode white paper there are three versions of STANAG 5066. MAC (Medium Access Control) layer was introduced in Edition 2 (which was later renamed as Edition 3) and designated to manage HF modem interface that DTS was designated to do the same before.
So is there a publicly-available specification that documents what the packets using this link-layer type look like?- This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
