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

How to add a new protocol

  • Clone.
  • Install ruby+kwalify.
  • Check structure-schema.yml.
  • Write protocol file in ./protocols/osi[layer]/[protocolname].yml.
  • Validate structure with 'kwalify -lf structure-schema.yml [path/to/protocolname].yml' or validate all at once with 'kwalify -lf structure-schema.yml ./protocols/osi*/*.yml'.
  • 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.
  • 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...
