+title: Data Plane Signaling
+date: 2026-01-19
+description: >
+  What are our reasons to adopt the Data Plane Signaling protocol and to deprecate the EDC Data Plane Framework
+---
+
+Data Plane Signaling is a specification for interoperable communication between Dataspace Protocol Control Planes and 
+Data Planes ([github project](https://github.com/eclipse-dataplane-signaling)).
+
+We decided to fully adopt this specification and to deprecate the current approach. This will involve deprecating the
+current implementation of the communication layer between the Control Plane and Data Plane in addition to the EDC Data
+Plane Framework.
+
+## Rationale
+
+The Data Plane Signaling specification addresses key architectural ambiguities by clearly delineating the roles of the
+Control Plane (orchestration and protocol-level authentication) and the Data Plane (actual data transfer and flow-specific
+authentication). This separation resolves design confusion, establishes symmetry between push and pull patterns, and,
+most importantly, creates a standard interface. This allows any application to become a compliant Data Plane,
+fostering innovation and moving the industry toward a future where data sharing is a seamless, integrated layer within
+sovereign applications, rather than a connector-centric task.
+
+## Approach
+
+The implementation of the Data Plane Signaling protocol in the EDC Control Plane is already progressing
+([issue](https://github.com/eclipse-edc/Connector/issues/5323)), we expect to have a fully compliant version as soon as
+a stable version of the Data Plane Signaling specification is released.
+
+At that point, we will deprecate the EDC Data Plane Framework in its entirety, and after 2 releases, it will be eligible
+for removal from the codebase. If you are an EDC adopter, we recommend to start prototyping your Data Plane(s)
+following the current specification. The dataplane-signaling team is already providing SDKs library in different
+languages ([Go](https://github.com/eclipse-dataplane-core/dataplane-sdk-go),
+[Rust](https://github.com/eclipse-dataplane-core/dataplane-sdk-rust),
+[Java](https://github.com/[eclipse-dataplane-core/dataplane-sdk-java](https://github.com/eclipse-dataplane-core/dataplane-sdk-java)),
+[.NET](https://github.com/[eclipse-dataplane-core/dataplane-sdk-net](https://github.com/eclipse-dataplane-core/dataplane-sdk-net)))
+to help with this transition.
+
+Let's see from the technical point of view what are the advantages brought by this approach.
+
+### How It Works Now
+
+These diagrams are showing the current state-of-the-art; some details have been intentionally left out to focus on the 
+scope of Control Plane and Data Plane interaction.
+
+Two issues become apparent just by looking at the diagrams:
+- **Vertical grouping**: The Data Plane is often considered part of the connector component together with the control 
+  plane. While this may not necessarily be an issue, it creates confusion for those building dataspace applications
+  regarding the correct boundaries and leads to poor design.
+- **Lack of symmetry**: The pull and push cases are handled quite differently on the consumer side, and the role of the
+  consumer’s Data Plane/client is not as clear as it should be.

+
+### How It Will Work with Data Plane Signaling
+
+Just a glance at the diagrams shows that a strong focus has been placed on separating the dataspace layer from the
+“use case/application” layer.  
+This is not to say they were not separated before, but this specification formalizes it: the Control Plane and Data
+Plane are two distinct architectural components serving different purposes.  
+While the Control Plane is responsible for wire protocol (DSP) communication and dataspace authentication, the Data
+Plane handles the actual transfer and receipt of data, managing authentication for the chosen data flow protocol.
+
+With this specification, any application meant to share data in a dataspace can implement the Data Plane Signaling
+specification and to become a Data Plane. This is the intended path forward: no more direct user-facing interaction
+with the connector, but rather an application layer that relies on the dataspace to provide sovereign data sharing.
+
+![new-pull.png](new-pull.png)
+
+Another interesting concept is that the data address is not managed by the Control Plane anymore: its creation and use 
+happens completely in the Data Plane, while the control-plane just takes care to pass it to the counter-part through DSP.
