Definition
Keepalive is a networking technology that retains a connection between two devices for a prolonged period even when not transmitting data. For example, it is mostly used to keep open connections between a server and a web browser.
When you visit a website, the browser connects with the server to send the request. Usually, this connection cuts off after a short while if the client and server stop communicating.
However, the Keepalive technology keeps the connection alive, enabling the server to send signals to the client regularly. This ensures quick subsequent requests and responses.
Keepalive Signals Benefits
- Network issue detection: Keepalive signals identify connection failures or device offline statuses.
- Resource conservation: Keepalive maintains open connections, saving resources on both client and server sides.
- Performance enhancement: Keepalive reduces latency during connection setup and termination, which is crucial for video streaming and online gaming.
