WebSocket is a communication protocol that provides full-duplex communication over a single, long-lived connection, enabling real-time data exchange between clients and servers. It emerged as a solution to the latency issues in traditional request-response protocols like HTTP. Key features of WebSocket technology include client-server communication, full-duplex communication, API Gateway, Transmission Control Protocol (TCP), Server-Sent Events (SSE), Cloud Run, and HTTP Streaming. Compared to traditional protocols, WebSockets offer persistent connections, reduced latency, efficient resource utilization, scalability, and bi-directional communication. VideoSDK leverages WebSockets for real-time video streaming and interactive features in web and mobile applications.
