Jini Technology Infrastructure: Discovery & Join

One of the key components of the Jini platform itself is called Discovery, the software that addresses the issue of how devices and software register with the network. When you plug a Jini-enabled device into the network, it drops a Discovery packet onto the network that enables it to be identified by the Jini Lookup service. The Discovery packet enables Jini services to find and join a Jini community, advertise their capabilities to the community of users, find and retrieve any needed software, and work with any device.
