An approach for establishing secure multicast communication among multiple event service nodes is disclosed. The event service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the event service nodes include the group session key and the private keys of the event service nodes that are members of the multicast or broadcast groups. The private keys provide unique identification values for the event service nodes, thereby facilitating distribution of such keys. Because keys as well as key version information are housed in the directory, multicast security can readily be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Event service nodes may obtain current key information from a local copy of the replicated directory.

A method, system and article of manufacture for managing metadata associated with a data abstraction model abstractly describing data in a database. One embodiment provides a method of managing metadata describing objects of a data abstraction model with logical fields that define abstract views of physical data in a database. The method comprises traversing a logical tree structure representing the data abstraction model. The logical tree structure has a plurality of nodes, each representing a logical field or a category of logical fields of the data abstraction model. The method further comprises identifying metadata describing logical fields or categories represented by the plurality of nodes. The identified metadata is stored in a queryable database. A user is allowed to query the database to identify objects in the data abstraction model that may be used to construct an abstract query.

A storage virtualization environment is provided that includes a network switch system for initializing a virtual volume in a system including a host system, and storage devices. The network switch system includes storage processors including first and second tier storage processors and a Virtualization Coherency Manager (VCM) for receiving storage connectivity identifying which storage processors are connected to selected ones of the storage devices. Further, the network switch system includes a master storage processor for creating a logical tree based on the storage connectivity information, the logical tree reflecting a virtual volume of data distributed across the storage devices and includes (i) first tier objects representing partitions of the virtual volume data and (ii) second tier objects representing a logical configuration of the virtual volume. In one embodiment, the VCM assigns the first tier objects to selective ones of the first tier storage processors and assigns the second tier objects to selective ones of the second tier storage processors based on the logical tree. Further, each of the selective first and second tier storage processors initialize a local portion of the virtual volume to allow the host system to access the virtual volume through the network switch system.

An approach for establishing secure multicast communication among multiple multicast proxy service nodes is disclosed. The multicast proxy service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the multicast proxy service nodes include the group session keys that are members of the secure multicast or broadcast groups. Because keys as well as key version information are housed in the directory, multicast security can be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Multicast proxy service nodes may obtain current key information from a local copy of the replicated directory.
