Abstract
A system manages the quantity of responses by discoverable lighting devices in a network, in responding to a device discovery request from a lighting control server. Each device includes a random target number accessible via the network, comprising a plurality of sequentially arranged fields, each field including a random target integer selected from a range of integers, based on a position of the field in the sequentially arranged fields of the random target number. The device discovery message includes a request to respond to the message if a specified value in the message compares with a target integer in a specified field of the random target number included in the receiving discoverable device, the specified value and specified field in the request based on an estimated percentage of the devices in the network expected to respond. Each device generates a response to the received request, if there is a successful comparison.
