Abstract: The transmittal of digital information from a customer to a client via the Internet is organized by employing a mediator and a handler. A customer requests the instantiation of a template from a mediator and the creation of necessary infrastructure for all subsequent media is done under the covers.

The mediator then makes digital information available to said handler and receives a media key from the handler identifying the digital information. Finally, the mediator sends the media key to the customer. Thus, customers are enabled to use rich media services without the burden previously required by just contacting a media e-utility provider offering media services.

Abstract: The present invention is a method of handling a wide range of dynamic groups of services where the makeup of the groups can be determined and changed while the application is running. This is mainly accomplished through a group proxy, which is generated at run time, and which handles interactions with groups of services on behalf of one or more clients. The group proxy consists of a group logic shell which contains all the group-aware logic, and a service proxy for each service in the group which contains the necessary logic to interact with the particular service. The group proxy, which is given to a client for all of its interactions with the group of services, buffers calls from that client to its group when the group is unavailable because it is in transition. When the transition is complete the group proxy transmits the stored client commands to the group.

The switch unit includes the number of packet buffers greater than the number of the host or disk interface units connected thereto, and can always hold the number of access requests greater than the number of the host or disk interface units.

The disk array system improves the efficiency of usage of internal paths without increasing the number of I/O ports of the switch unit. The system throughput is thereby improved, and the support for host I/Fs having different performance is thereby facilitated.
