Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address. Each network device receiving the ELM may then propagate the ELM on a plurality of its ports to a plurality of downstream network devices based on the target address. In addition, each receiving network device returns an exploratory linktrace reply (ELR) for each of the plurality of ports, where each ELR is returned according to one or more mechanisms to mitigate stormed replies to the initiating network device.

Abstract: A location services system used with a wireless LAN network provides wireless LAN Internet access in a venue, and also provides location-based analytics and services. The system monitors the locations of individuals using devices that communicate with a network, and maintain statistics for analytical purposes, and can provide services, such as special promotions and discounts. The system can determine whether a single person is carrying multiple devices, e.g., a user carrying a cellphone (including a smartphone) and a tablet or a laptop; and can also determine whether multiple people are within the venue as a temporary logical group, such as a family or group of friends. These capabilities allow the system to adjust how it communicates with users, and also allows it to adjust the analytics.
