Introduction

Information-Centric solutions, also known as data-centric solutions, have been proposed and researched over the last decade without truly seeing adoption from the industry. Instead, the industry still heavily relies on “non-native” data-centric solutions, like MQTT or DDS, that emulate a data-centric behavior tied to the limitations of host-centric solutions, making them sub-optimal or inefficient. In addition, current solutions are typically targeting a single communication paradigm (either pub/sub or req/rsp) or a specific segment of the Cloud-to- Thing continuum.

Eclipse Zenoh aims at offering an open-source data-centric solution adapted to the industry. It unifies data in motion, data in-use, data-at-rest, and computations by carefully blending traditional pub/sub with geo-distributed storages. At the same time, it retains a level of time and space efficiency that is well beyond any of the mainstream offers. Zenoh provides a stack designed to (1) minimize network overhead, (2) support both extremely constrained devices, and powerful applications in the cloud, (3) support devices with low duty-cycle by allowing the negotiation of data exchange modes and schedules, (4) provide a rich set of abstractions for distributing, querying, and storing data along the entire system, and (5) provide extremely low latency and high throughput. By doing so, Zenoh can target the most powerful as well as the smallest things, thus covering the whole Cloud-to-Thing continuum.

After several years of careful design and performance assessments, we consider that, in 2022, Zenoh is mature and ready for its next stage of dissemination. With clear contributions in the automotive (e.g., Indy Autonomous Challenge) and robotics (e.g., ROS2) sectors, boosted by to the fact that is completely open-source, Zenoh can become a de-facto solution on the ICN landscape. ACM ICN 2022, as the flagship conference on the topic, can help us reach an even higher audience of experts in data-centric solutions and networks in general, thus contributing to not only on-going research discussions but also for future developments. As open source, the research community will also benefit from such developments.
