L2tasot

L2tasot is an open‑source distributed operating system that focuses on low‑latency communication and efficient resource management. It was first announced in 2018 by a consortium of research institutions from North America and Europe, and the first stable release, version 1.0, was published in 2020. The system is written primarily in Rust, with critical performance layers implemented in C++ for kernel modules. L2tasot is designed to run on commodity servers as well as on edge devices, providing a unified kernel that abstracts differences between clustered, cloud‑native, and embedded environments.

The architecture of L2tasot is modular. A lightweight control plane handles dynamic topology discovery and fault tolerance, while a high‑performance data plane routes packets with minimal context switching. Native support for RDMA, InfiniBand, and 5G NR allows the system to deliver sub‑microsecond latency in data‑center and telecommunications applications. The scheduler in L2tasot implements a fair‑share policy that adapts to application priorities, making it suitable for real‑time workloads such as high‑frequency trading and industrial automation.

Since its release, L2tasot has been adopted by several telecommunications operators for back‑haul data processing and by research laboratories for experimenting with new protocol stacks. The project’s community actively maintains a public package repository, and it is available under the Apache 2.0 license. The latest major release, 2.5, introduced native support for container orchestration engines and improved compatibility with Kubernetes. L2tasot continues to be developed with contributions from academia and industry, aiming to provide a high‑performance, low‑latency operating environment for next‑generation networked applications.
