The latency of a node is the amount of time that it takes the node to respond to messages.

The unicast latency of a link is the amount of time that it takes the link to propagate a message from a source interface to a single destination interface. The broadcast latency of a link is the amount of time that it takes for the link to propagate a message to all interfaces attached to the link. (Likewise for multicast latency.)
