Chapter 5: Data Plane Architecture

The EDC architecture separates the Control Plane (which handles protocol communication, catalog, contracts, and trust) from the Data Plane (which handles actual data transfer). The two communicate through the Data Plane Signaling protocol.

The Control Plane handles trust, contracts, and protocol negotiation. The Data Plane handles the actual data transfer using the wire protocol appropriate for the use case — HTTP, streaming, file transfer, or others.

For the rationale behind this architecture and how it works, see the Data Plane Signaling blog post.
