Ouroboros Implementation Overview

 This page is under construction  

The Ouroboros prototype is far from complete. In order to come to a usable production version, a lot more implementation is needed. We have a kanban board tracking to-do items.

This page provides an overview of the current implementation status of the O7s prototype. It follows the directory structure of the repository and for each item explains what is currently implemented, stability of the current implementation, what is planned and the direction we would like to move towards. Some big items, the most prominent one being management of namespaces (ownership and scalability of service names) have not started yet.

Ironically, this page is currently even less complete than the prototype. Bear with me.

Library

The ouroboros library

Application end-to-end functions

These are the functions that are typically called by an application programmer to interact with the network.

Application end-to-end background tasks

These functions are background tasks that are not directly visible to the application programmer.

FRCT

FRCT, implements FRCP

Authentication

Not yet implemented.

Integrity

CRC

IPCPs

Common

This implements

Flow allocator

Ouroboros Flow Allocation Protocol

Packet Transfer

ODTP

Tools

irm

Main page: Ouroboros Command Line Interface

Programming language support

The prototype itself is written in C for performance, but bindings for other languages are available or planned

Golang

Planned

Python 3

pyOuroboros

Rust

A rust interface is available.

Other tools

Logging

The Ouroboros log format:
Example:

==06773== irmd(II): Created IPCP 6794.
==06794== ipcpd/ipcp(II): Bootstrapping...
==06794== ipcpd/ipcp(II): Finished bootstrapping:  0.
==06773== irmd(II): Bootstrapped IPCP 6794 in layer local-layer.

With ==<process number>== <O7s component>(<log level>): <log message>

• II = info
• DB = Debug
• WW = Warning
• EE = Error

A parsable format for observation is still to be implemented. Logging to syslog is interesting, since the format is more standard.
