Abstract: Systems and methods of announcing device communication availability are disclosed. A first computing device encodes first profile information into an announcement message. The announcement message includes an address field for storing a data link layer address, and the first profile information is encoded into the data link layer address stored in the address field. The first computing device then broadcasts the announcement message. Upon receipt of the announcement message at a second computing device, the second computing device decodes the data link layer address stored in the address field of the announcement message, to extract the first profile information. The second computing device compares the first profile information to second profile information stored at the second computing device; and based on the comparison, determines whether the first computing device is suitable for communication with the second computing device.
