Discovery in Brief

1. The device advertises and looks for a service

2. Lookup Servers run instances of thediscovery service which listen for multicast requests from discovering entities

3. The discovering entity performsa multicast that requestsreferences to the lookup service.

4. The lookup server calls a remote method on thediscovering entity’s exported object instance passing aremote reference to its lookup service as the parameter
