Dissectors get done/extended whenever someone finds the time/intrest to
do so. Withe BACnet there is another stopper
As the protocol isn't freely avalable any extension to the dissector has
to be done by someone with access to the protocol spec. and sample
traces.

Subject: [Wireshark-dev] Introduction and first questions/suggestions

Hello,

since I signed up this list just recently, I take the opportunity to
introduce myself. My full name is Dr. Simon Ginsburg and I'm Product
Manager for communication protocols/products for the company Saia-
Burgess Controls Ltd in Switzerland. This is the company, where my
college Christian Durrer has already written a dissector included in
Wireshark for our proprietary field bus called "S-Bus".

One of my main fields of activity currently is the implementation of the
BACnet protocol into our PLC (Programmable Logic Controllers).  
For testing, training, support and training purposes I frequently use
Wireshark and also tell our customers with technical problems in the
field to send my not only their project but also trace logs usually
taken with Wireshark.

During recent support call treatments I discovered some fields of
improvements. Before I adding them to the long list of whishes or in the
Wikipedia, I wanted to check that I have not overlooked something.

Wishlist:

Either under Chapter "GUI" or "Dissection":
When a protocol is used on another port than Wireshark expects it to be
(such as BACnet on UDP port 48560) the context sensitive menu Item
"Decode as..." is GREAT, but finding what I need is not so great since
only an abreviation (in above example BVLC) can be selected without any
way of help. I suggest a tooltip when hovering over a selected protocol
item with the same content as in help --> Supported Protocols  (in above
example BVLC: BACnet Virtual Link Control).

Dissector specific
Item 19. What's the reason, the APDU part of BACnet/IP is not dissected?
Is it just the workload (for which a solution can be
found) or there a technical reason such as variable length, the BACnet
specific solution of segmenting or other?

Wikipedia:
BACnet is not easy to find. IMHO it's also a member of the
"FieldbusProtocolFamily" as is LON and EIB, the first using "IP-852",
the latter EIBnet/IP for the transport over IP. Is it OK that I extend
the Wiki pages accordingly?

Sincerely
Simon
