Pong

Noun · Development

Definitions

  1. The response message sent back after receiving a ping, used in network protocols (ICMP, WebSocket, IRC) to confirm that a connection is alive and measure round-trip latency. In WebSocket, the server sends a pong frame in reply to a client's ping frame to keep the connection from being closed by intermediaries.

    In plain English: The reply message sent back when something checks if a connection is still alive — it's the 'I'm still here' response to a ping.

    Example: "The load balancer drops the connection if it doesn't get a pong back within 30 seconds, so make sure your WebSocket handler responds to pings."
