ZeroTier Network Hypervisor Core
|
|
======
|
|
|
|
This directory contains the *real* ZeroTier: a completely OS-independent global virtual Ethernet switch engine. This is where the magic happens.
|
|
|
|
Give it wire packets and it gives you Ethernet packets, and vice versa. The core contains absolutely no actual I/O, port configuration, or other OS-specific code (except Utils::getSecureRandom()). It provides a simple C API via [/include/ZeroTierOne.h](../include/ZeroTierOne.h). It's designed to be small and maximally portable for future use on small embedded and special purpose systems.
|
|
|
|
Code in here follows these guidelines:
|
|
|
|
- Keep it minimal, especially in terms of code footprint and memory use.
|
|
- There should be no OS-dependent code here unless absolutely necessary (e.g. getSecureRandom).
|
|
- If it's not part of the core virtual Ethernet switch it does not belong here.
|
|
- No C++11 or C++14 since older and embedded compilers don't support it yet and this should be maximally portable.
|
|
- Minimize the use of complex C++ features since at some point we might end up "minus-minus'ing" this code if doing so proves necessary to port to tiny embedded systems.
