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.

Abstract: In an example, an access point includes a first and second Ethernet port, a processing resource and a memory resource storing machine readable instructions. The machine readable instructions may be to cause the processing resource to create a first communication channel between the access point and a first network zone using the first Ethernet port and to create a second communication channel between the access point and a second network zone using the second Ethernet port. The first and second network zones may be independently configured with respective first and second zone controllers and the first and second communication channels may exist simultaneously.

Abstract: An example of a system may include a processing resource and a computing device comprising instructions executable by the processing resource to determine an interval based on an amount of time to upgrade a network; determine a series of time windows based on the interval; analyze data traffic in the network over the series of time windows; identify a subset of the series of time windows that are sequential and non-overlapping; and select a particular time window from the subset of the series of time windows to perform an upgrade of the network based on the analyzed data traffic.

Abstract: In some examples, a non-transitory machine-readable storage medium having stored thereon machine-readable instructions to cause a computing processor to track a Layer 2 (L2) bit indicating a L2 connectedness between a first user anchor controller (UAC) corresponding to a client device and a second UAC acting as a standby UAC for the first UAC in a controller cluster, and reassign a third UAC to be the standby UAC for the first UAC in response to the L2 bit indicating that the first UAC is not connected to the second UAC in the same L2 network, wherein the first UAC is in the same L2 network as the third UAC.
