Abstract: An apparatus, computer program product, and method relating to identifying and configuring an access point (AP) as a network sniffer. A network controller identifies a plurality of sniffer targets for which at least one of a plurality of sniffer candidate access points an act as a network sniffer. The controller receives a desired sniffer target. The controller selects a first AP, of the plurality of sniffer candidate APs, for use as a network sniffer, based on the identified plurality of sniffer targets and the desired sniffer target. The controller configures a radio in the first AP as a network sniffer to monitor network traffic related to the desired sniffer target.

Abstract: Improved mesh performance using Overlapping Basic Service Set (OBSS) coloring and transmission scheduling may be provided. A controller may determine that a plurality of Access Points (APs) in a mesh network each have a Received Signal Strength Indicator (RSSI) that is in a predetermined range. Next, the controller may assign, in response to determining that the plurality of APs each have the RSSI that is in the predetermined range, OBSS colors to links between the plurality of APs to limit packet collision in the mesh network between the plurality of APs. The controller may then create a transmission schedule for transmissions between the plurality of APs in the mesh network based on the assigned OBSS colors.
