## README

### mstp-lib
A library that implements the Multiple / Rapid Spanning Tree
Protocol as defined in 802.1Q-2018.

It's written in C++03 and is callable from C.

I integrated the library myself in various devices made by
various OEMs (ship automation, tactical networking, in-flight
entertainment) and I helped others integrate it in plenty other
devices.

### Simulator
A Simulator application for Windows is provided - both
sources and [binaries](https://github.com/adigostin/mstp-lib/releases).
The Simulator lets you create networks and see the library
in action. See the screenshot below. This is a project for
Visual Studio 2017.

### Embedded Application Examples
The repository includes sources with a couple of RSTP implementations
on embedded devices with microcontrollers and switches such as
Marvell, Microchip, IC+. The projects are for Rowley CrossWorks
(gcc and clang compilers) and IAR Embedded Workbench (EDG compiler).

These samples highlight the platform-specific
code required by STP -- mostly code that writes to
a few hardware registers of the switch chip. To integrate
the library in your embedded application, you'll need to
write platform-specific code for your particular switch IC.
