Data Handling in EAST Remote Participation

International collaboration has become increasingly frequent in fusion research. It improves the quality and efficiency of the research in Experimental Advanced Superconducting Tokamak (EAST) facility. The traditional face-to-face collaborative way has been proven inadequate in current situation. The remote participation system (RPS) for EAST (EAST RPS) will play an important role in EAST operation experiment. Data handling for remote access through Internet are a critical issue for EAST RPS. There are three types of data in EAST RPS: engineer data, scientific raw data, and camera data. This paper presents the technical solutions for data handling in EAST RPS including the system architecture, data compression technologies, protocols, and a new experimental physics and industrial control system data archiving Engine.
