Relays are leveraged to enable distribution scale in the MOQT architecture. Relays can be used to form an overlay delivery network, similar in functionality to Content Delivery Networks (CDNs). Additionally, relays serve as policy enforcement points by validating subscribe and publish requests at the edge of a network.

Relays are endpoints, which means they terminate Transport Sessions in order to have visibility of MOQT Object metadata.

For the purposes of this specification, a coordinated set of relays are treated as a single MOQT relay. How relays within such a set interconnect, and use cases built on relay to relay communication, are out of scope.

This is one section of the MoQT specification, rendered per-section for quick reference and citation. The authoritative text is draft-ietf-moq-transport-22 at the IETF.
