Abstract
Some examples relate to detecting network link failure. In an example, a determination may be made at a first network device on a network regarding an average round-trip delay time (RTD) between the first network device and a second network device over a given time interval during a given period of time. Then, for the given time interval, a keepalive packet may be sent from the first network device to the second network device at the average RTD of the given time interval for a keepalive time. In response to a determination, by the first network device that there is no acknowledgement of the keepalive packet from the second network device during the keepalive time, a network link between the first network device and the second network device may be identified as failed.
