Crate libp2p_ping 

This module implements the /ipfs/ping/1.0.0 protocol.

The ping protocol can be used as a simple application-layer health check for connections of any Transport as well as to measure and record round-trip times.

Usage

The Behaviour struct implements the [NetworkBehaviour] trait. It will respond to inbound ping requests and periodically send outbound ping requests on every established connection.

It is up to the user to implement a health-check / connection management policy based on the ping protocol.

For example:

• Disconnect from peers with an RTT > 200ms
• Disconnect from peers which don’t support the ping protocol
• Disconnect from peers upon the first ping failure

Users should inspect emitted Events and call APIs on Swarm:

• Swarm::close_connection to close a specific connection
• Swarm::disconnect_peer_id to close all connections to a peer
