Hello, dear IETF community. I would like to develop L7 protocol for my application and public documentation about it. Good protocol development is quite difficult stage, but not a problem. But at the same time, I don't have any experience writing protocol documentations (RFC's). What guidelines do you have? Is the RFC 4253 (SSH) good example of document design? Should I follow same principle? Please give me some examples how to make it correct. Even examples of very simple protocols. What I need as requirements: TCP/UDP transport Authentication Encryption Sequence control My protocol would carry small status messages like (10-20 bytes with timestamps and some sort of sequence synchronization). Thank you very much for your answers. Sorry for posting into the general list. -- Philippe Duke Network software engineer System-level developer NetAssist LLC Ukraine Khreshchatyk Street, 10B, office 8 AS29632 http://netassist.ua Our GitHub Repository: https://github.com/netassist-ua
