Add specific examples to clarify message protocol

The documentation would be more helpful if there were some examples. To begin with, following examples would be quite beneficial:

• Example of request mentioned in https://github.com/opendcs/dcs_standards/blob/main/source/dds-14.rst#dds-requestresponse-headers
• Example of Authenticated Hello including a walk-through of hash construction mentioned in https://github.com/opendcs/dcs_standards/blob/main/source/dds-14.rst#authenticated-connection
• Example of Sending a Transient Network List to the Server mentioned in Sending a Transient Network List to the Server

That's a good idea. I'm not sure when I'd have time to work on it. Though I can point you to the code.

That does someone lead to a question though. There is currently a plan to switch to (or at least add) a "DDS over HTTP" protocol. I'd be more inclined to focus on doing that since in theory it would just be easier for anyone to implement a client or server. But for you I suspect that would depend on if you're under any deadlines for your current effort?

The idea being that a new protocol would be to simplify certain things such as login (already covered by HTTP) and data transfer formats.

Still value in better documenting our current protocol though as it could still inform any new one, and it won't go away immediately.

Could you point me to the code?

Where can I read about the "DDS over HTTP"?

[MikeNeilson]

For DDS over HTTP, we don't have anything yet. There's initial ideas here: opendcs/opendcs#152, the concept is still in its infancy.

For the current DDS protocol: https://github.com/opendcs/opendcs/blob/master/src/main/java/lrgs/ldds/CmdAuthHello.java
And others in that directory.
