Peer groups are formed as a collection of peers that have agreed upon a common set of services.

The Service advertisement provides the necessary information to uniquely identify the service and to contact its associated service(s). <p/>When a new peer is joining a peer group an instance of all the services associated with the new peer group is created on this peer dynamically.
