CHOICE OF DATA TRANSMISSION TECHNOLOGY FOR HIGH-LOAD FINANCIAL SYSTEMS USING WEBSOCKETS, SSE, AND GRPC

Zolotukhina D. U.

The article presents a study of data transmission technologies WebSockets, SSE, and gRPC in the context of their application to high-load financial systems. A Java-based program was developed to simulate real-time transmission of financial quotes under various load levels. Key metrics, including latency, throughput, connection stability, and resource consumption, were measured. The obtained data allow for identifying the most suitable technology for different scenarios of financial applications.
