Network Protocol Dictionary

This is a YAML network protocol dictionary for all (binary based) OSI-Layer 1-4 protocols, eg. Ethernet, IP, TCP, UDP, etc.

  • What this dictionary should be:

    • A complete machine readable structure definition dictionary for all binary based network protocols
    • Addon: some protocol documentation from wikipedia or RFCs for display use.
    • A reference for building a network packet from scratch in an application, mostly for applications dealing with network packets.

  • What it is clearly NOT:

    • Currently: complete.
    • A replacement for reading RFCs: Dependencies and constraints are NOT defined in this dictionary
    • A source for implementing network stacks

Why?

I have a project where I want to use a non platform dependent source for network protocol structures so I want to avoid using the defined structures in the OS includes which depend on the operating system used at program execution. Simple, isn't it?

How to add a new protocol

Requirements:

  • Python 3.5
    • jsonschema
    • PyYaml
  • (the old kwalify schemas are still present, but deprecated.)

Howto:

  • Clone.
  • Check structure-schema.yml.
  • Write protocol file in ./protocols/osi[layer]/[protocolname].yml.
  • Validate structure with 'python validate.py -f [path/to/protocolname].yml' or all at once with 'python validate.py --all'
  • Set up a merge request.
  • Be happy.

How to use this dictionary

Currently not recommended, because the project lacks deeper tests than just schema validation. ;)

  • Clone.
  • Get a YAML library for your program language. Or get a converter for JSON or XML, to use these markup languages.
  • Load desired protocol files, or all of them.
  • Use resulting data structures to build protocol packet structures.

This repository will provide examples or useable code snippets for specific programming languages in the future...
