Discussed VTP stream aggregation. Agreed that we need to use accepted taxonomy, where we distinguish between frame aggregation and an event building.
It was mentioned that the ERSAP framework development is at the stage that it is possible to design proof of concept implementations and test-beds for the JLAB streaming DAQ, as well as EJFAT UDP data stream transport and reassembly engine processing.
Mike provided EJFAT white paper that will trigger future discussions and strategic planing.
A short demo was presented showing an ERSAP application in action that receives streaming data in the DAS format from the SAMPA DAQ, passing it through 2 toy polyglot services.
