Design first version of Match-Action table on RIC API GW

RIC-API-GW allows all components like Redis DB, ONOS, XOS, RIC Southbound (or O-RAN Southbound), and any other realtime apps to communicate with each other. To send a message from one to the other app, each app should be connected to an appropriate bundle running in the gateway.

In this situation, one bundle must pass messages received by the app to the other bundle(s) associated with the other app(s). The first release of RIC-API-GW is working like a bundle explicitly states the name of destination bundle. What if the source bundle wants to send messages to multiple apps through bundles? Or, what if the source bundle wants to send whole messages to some apps and send the part of messages to the other apps?

To solve this problem, the way with Match-Action table is quite suitable. Will develop the initial version of Match-Action table on GWCore bundle in RIC-API-GW.
