5GMETA MEC Platform Registration APIs

This project contains all the components needed to implement the Registration API, a Flask webserver running on the Edge, providing REST APIs to interact with a dataflow database.

Interactions

The registration apis interract with:

• the Cloud Dataflow DB, to add informations about the active dataflows;
• the S&D application, retrieving from POST request the information about new dataflows;
• the S&D application, retrieving from PUT requests the dataflows keepalives.

API Description

The yaml description of the APIs is provided in the api folder.
The provided endpoints are:

• POST /dataflows, that receives the dataflow metadata as body in the request, adds the new dataflow to the DB and returns a JSON; this JSON contains:
  • the dataflowId;
  • the amqp topic where to send the messages;
  • a boolean value called "send", if "send" is True, at least one consumer in the 5GMETA platform is interested in the dataflow registered.
• PUT /dataflows/<dataflowId>, that receives the dataflow metadata as body in the request and performs several operations:
  • modifies the metadata associated to a specific dataflow;
  • functions as a keepalive, if the sender does not send this PUT periodically (every 30/60 seconds), 5GMETA will delete the dataflow;
  • generates the same response as the POST /dataflow, but may update the "send" value if the consumers change.
• DELETE /dataflows/<dataflowId>, that deletes a specific dataflow.
