why not using existing ses, pres and acse dissectors ?
- ATN upper layers are derived from OSI standards for session,
- presentation and application but the encoding differs
- (it's PER instead of BER encoding to save bandwith).
- Session and presentation use the "null" encoding option,
- meaning that they are only present at connection establishment
- and ommitted otherwise.
- Instead of adapting existing dissectors it seemed simpler and cleaner
- to implement everything the new atn-ulcs dissector.

why using conversations ?
- PER encoded user data is ambigous; the same encoding may apply to a CM or
- CPDLC PDU. The workaround is to decode on a transport connection basis.
- I use my own version of conversations to identify
- the transport connection the PDU belongs to for the standard functions
- from "conversation.h" didn't work out.

what is the use of AARQ/AARE data ?
- Converstions should be maintained on the COTP layer in a standard way
- for there are usually more packets available than in the layers above.
- In the worst case my dissector is called from a DT packet which
- has destination references but no source reference.
- I have to guess the reference used the other way round
- (curently I am using ACSE PDU'S used during OSI connection establishment for that).
- The idea is that each ACSE AARQ is answered by ACSE AARE and having this sequence
- I have all the source/destination references for this transport connection.
- I use AARQ/AARE data to store the source/destination reference of AARQ as well
- as the optional ae-qualifier which tells me the application and
- the dissector I have to use.
- This approach donesn't work well when there are interleaving AARQ/AARE sequences for
- the same aircraft.

which ATN standard is supported ?
- The dissector has been tested with ICAO doc9705 Edition2 compliant traffic.
- No ATN Secutity is supported.
- note:
- The ATN upper layers are derived from OSI standards (ICAO DOC 9705)
- while ATN/IPS (ICAO DOC 9896) which is entirely based on IPV6.
