Introduction

Welcome to iceoryx2, the efficient, and ultra-low latency inter-process communication middleware. This library is designed to provide you with fast and reliable zero-copy and lock-free inter-process communication mechanisms.

So if you want to communicate efficiently between multiple processes or applications iceoryx2 is for you. With iceoryx2, you can:

• Send huge amounts of data using a publish/subscribe, request/response, pipeline (planned) or blackboard pattern (planned), making it ideal for scenarios where large datasets need to be shared.
• Exchange signals through events, enabling quick and reliable signaling between processes.

iceoryx2 is based on a service-oriented architecture (SOA) and facilitates seamless inter-process communication (IPC).

It is all about providing a seamless experience for inter-process communication, featuring versatile messaging patterns. Whether you're diving into publish-subscribe, events, request-response, or the promise of upcoming features like pipelines, and blackboard, iceoryx2 has you covered.

One of the features of iceoryx2 is its consistently low transmission latency regardless of payload size, ensuring a predictable and reliable communication experience.

iceoryx2's origins can be traced back to iceoryx. By overcoming past technical debts and refining the architecture, iceoryx2 enables the modularity we've always desired.

In the near future, iceoryx2 is poised to support at least the same feature set and platforms as iceoryx, ensuring a seamless transition and offering enhanced capabilities for your inter-process communication needs. So, if you're looking for lightning-fast, cross-platform communication that doesn't compromise on performance or modularity, iceoryx2 is your answer.

[^1]: A proof-of-concept for Android platform support is available. Currently only local, inter-thread communication works. [^2]: A proof-of-concept with no_std bare-metal support is available. The event messaging-pattern does not yet work and the memory usage is not yet optimized. [^3]: A proof-of-concept for VxWorks platform support is available on this branch on the ekxide fork

• tier 1 - All safety and security features are working.
• tier 2 - Works with a restricted security and safety feature set.
• tier 3 - Not tested in our CI, so may or may not compile and run.

[!NOTE] Some commercial operating systems require expensive licenses and the support for these platforms relies on funding for the license costs.

[!NOTE] Yocto recipes are available at meta-iceoryx2

Thanks To All Contributors

Thanks to everyone who has contributed to iceoryx2. Without their passion and dedication, the project wouldn't thrive. A list of people who have committed code can be found on github. However, contributions are not limited to code - testing the software, reporting bugs, and spreading the word about iceoryx2 are all equally valuable. A big thank you as well to those 'invisible' contributors who play a crucial role behind the scenes.
