Abstract: During operation, an access point may receive, from an electronic device, a roaming request, where the electronic device is currently associated with a second access point. In response, the access point may broadcast a message in a network, which includes the access point and the second access point. Note that the message may include an L2 look-up message. In some embodiments, the message is only conveyed to the second access point via a router or a switch in the network. Then, the access point may receive, from the second access point, PMK information, where the second access point is included in a subset in the network with the access point. Next, based at least in part on the PMK information, the access point may generate a PMK for use during secure communication with the electronic device and may perform a fast BSS transition with the electronic device.

Abstract: Methods, systems, and devices in which a computer networking device may compare the destination address of the a name resolution request with a stored list of addresses. If the destination address does not match any of the addresses from the stored list, the computer networking device may perform one or more actions, such as sending a notification, redirecting the name resolution request to one of the servers in the list, or generating a new name resolution request. For example, a method may include receiving network traffic from a client device including a first name resolution request; comparing a first destination address from the first name resolution request with a list of addresses indicating servers to which the client device is to communicate name resolution requests; and detecting that the first destination address does not match any of the addresses from the list of addresses.

Abstract: Methods, systems, and devices for performing analytics on communications networks. For example, methods may include receiving, at an access point of a wireless network, a first transfer unit comprising first data destined for a first destination; receiving, at the access point, a second transfer unit comprising second data destined for a second destination; grouping, by the access point, the first and second transfer units into a group; and calculating, by the access point and based on the transfer units of the group, a response time associated with the first destination based on a time difference between the receiving of the first transfer unit and the receiving of the second transfer unit. The transfer units may comprise encrypted data.
