For the creation and self-organization of peer-groups the JXTA protocol may be used, which includes messages such as peer or peer-group advertisements and services such as the discovery service. Conventional peer-groups of this type are static and need restart after any modification, e.g. a new service. A method for dynamically managing hardware and/or software elements, e.g. services, utilized and/or offered by such peer-groups comprises detecting a change within a peer-group (OZ), creating a new peer-group identifier, publishing within the peer-group a first peer-group advertisement message (PGA1) that includes the current and the new peer-group identifier and pointers to current services including the detected modification, accepting the new peer-group identifier by the other peer-group members, and publishing a second peer-group advertisement message (PGA2) in the superordinate peer-group (NPG), wherein both advertisement messages may be identical. Thus, peer-groups may operate continuously while peers modify, add or delete services.
