Patent ID: 11665136

Abstract:
An access point that selectively provides a multicast domain name system (mDNS) message is described. During operation, the access point may receive an mDNS message, where the mDNS message includes an identifier of a group (such as a user group). For example, the identifier of the group may be included in the mDNS message when the mDNS message includes discovery information for a service. Moreover, the identifier may specify the portion of a subnet in a wireless local area network (WLAN) in a geographic region, such as a room, a floor or a building. Then, the access point may determine whether the access point or an electronic device is included in the group. When the access point or the electronic device is in the group, the access point may selectively provide the mDNS message addressed to the electronic device. Otherwise, the access point may drop the mDNS message.
