WebSocket
WebSockets provide a bidirectional communication channel over a single, long-lived connection. This enables real-time, low-latency data exchange between a client and a server.
WebSocket Protocol
1. WebSocket Handshake:
The WebSocket handshake is an HTTP-based protocol that establishes a connection between the client and server. Once established, the connection switches to the WebSocket protocol.
2. WebSocket Frames:
Messages in WebSockets are sent as frames. Frames can be text, binary, or control frames used for connection management.
Usage and Benefits
1. Real-Time Applications:
WebSockets are ideal for real-time applications like live chats, online gaming, financial trading, and collaborative tools.
2. Reduced Latency:
The persistent connection minimizes latency compared to traditional HTTP, making WebSockets suitable for applications requiring low-latency communication.
3. Efficient Data Transfer:
WebSockets use a compact binary frame format, reducing the overhead associated with text-based protocols.
