....: a brokering functionnality is offered, either by dedicated machines (centralized systems) or by the particpating machines themselves. In both cases, scalability is a major issue. For centralized systems, classical hierarchical organizations derived from the LDAP protocol are under investigation [26]. For decentralized implementations of the broker layer, only very preliminary results on the scalability issue are currently available [32] 3 Performance Scheduling presumably is the key for application performance in the context of a GCS environment. There is a general consensus about the ....

....version and everybody wants to download it) the storage object locates additional object servers and requests them to create a new replica. The additional object servers are located using the Globe Infrastructure Directory Service (GIDS) which keeps track of the object servers available worldwide [9] When popularity drops and it becomes inefficient to maintain a replica at a certain object server the storage object removes the replica and unregisters it from the location service. 2.1 The structure of Globe objects The local representatives of a Globe object are composed of subobjects, ....
....Globe objects. As a result, one cannot generally call other Globe objects from inside a semantics subobject. Long term blocking (i.e. waiting on a condition variable) is not allowed, to limit the number of blocked threads and reduce resource usage [18] Continuations should be used instead [19] The semantics subobject should be able to marshall and unmarshall its state. For historic reasons, a programmer cannot, at present, fully exploit Java s serialization facilities, but has to implement a Globe specific SemanticsSubobject interface. This interface consists of two methods, one ....

....sense, GIDS is similar to Active Directory [14] an important difference being that GIDS servers constitute only GIDS is Dutch for guide. 13 leaf nodes in the name space. Intermediate nodes are always DNS servers. This difference makes GIDS more efficient. Details on GIDS are described in [12]. 5 Security One of the more profound aspects of GDN is its support for security. Obviously, a system such as GDN should be able to provide protection against various security attacks. In addition, and perhaps more important considering the various peerto peer file sharing mechanisms currently ....

The additional object servers are located using the Globe Infrastructure Directory Service (GIDS) which keeps track of the object servers available worldwide [3]. When popularity drops and it becomes inefficient to maintain a replica at a certain object server, the object removes the replica and deregisters it from the location service. 2.1.
