Protocol Architecture
Zenoh as a DDS Alternative
DDS remains a foundational real-time publish-subscribe standard. Zenoh addresses a different deployment reality: systems that must span tiny devices, robots, edge networks, data centers, and cloud services with one data-centric abstraction.
Concern
Traditional DDS Fit
Zenoh Fit
Local real-time domains
Strong
Strong via integration patterns
WAN and cloud traversal
Requires extra architecture
Native design target
Constrained devices
Often heavy
Protocol family includes embedded targets
Queries and storage
Outside core pub/sub model
Part of the core abstraction
