# Protocols
## Summary
First a high-level description of protocols and implementation status. Each
topic links to the second table with more detailed implementation status per
RFC.

## RFCs
The mox source code is quite heavily annotated with references to the RFCs.
This makes the implementation more maintainable, and makes it easier for new
developers to make changes. See [cross-referenced code and RFCs](../xr/dev/) to
navigate RFCs and source code side by side.
Implementation status per RFC, grouped by topic.
