osi-stack

ISO/ITU-T/IETF OSI (Open Systems Interconnection) stack implementation with application protocols.

Status: Work in progress.

Currently featuring:

parts of CLNP over ...
Ethernet Subnetwork Service
via Ethernet2 header.
Ethernet SN:
- PDUs implemented.
- Functions working, but need to check conformance.
- Primitives implemented (SN Unitdata request, SN Unitdata indication).
CLNP NS:
- Most CLNP NS PDUs implemented (Data PDU, Echo Request, Echo Response).
- Functions partly implemented
- Primitives mostly implemented.
- Echo Request and Echo Response handling and "ping" roundtrip
Simple static resolving of system-title based NSAP to SNPA address.
Simple OSI ping application

Working on:

Goal:

Full coverage of the OSI protocols up to CASE (ACSE, RTSE, ROSE).
- Maybe support for connection-oriented Data Link/Subnetwork Service and Connection-oriented Network Service.
Routing protocols ES-IS, IS-IS and IDRP.
LLC header support.
Option to use IP suite of protocols for carrying OSI PDUs
Carrying IPv4+IPv6 payload in routing protocols and in NLPID.
Management support.
Transport Layer Security, Network Layer Security.
Application-layer protocols FTAM, VT, ...
X.400
X.500
X.509 (note, consider https://en.wikipedia.org/wiki/X.509#Security)
X.400 EDI
X.601
X.605
X.609
and others in X-Series
Linux kernel module for layer 2,3,4
multi-platform support (Linux, Mac, Windows)

SS7 support (built on OSI)
ATN support (built on OSI, transitioning from OSI as base to IP in newer airplanes)
OPC UA (running via TCP, but may run via TP4 as well)
energy exchange protocols

Written in Rust, with planned binding for C and further, more programming languages.
