Network Protocol Implementation

I'm going to implement a network protocol (specifically SFTP), and I wondered if there are any general rules to follow?

At the moment, this seems like a gigantic task, and I do not understand where to start.

I'm looking for:

  • Advice
  • Best practics
  • Possible design patterns
  • An experience

Try to save it in relation to network protocols in general.

Thank!

I would certainly recommend using proven libraries, if possible. Especially for SSH, the SFTP side - because implementation errors can lead to security vulnerabilities.
