A method and apparatus for authorizing a file to use stored information for executing a process in a Linux operating system. The file includes an executable linking format, an application authorization data, and other attributes for the application.

In an address management system, an interface ID can be handed over from one apparatus to another without losing the correspondence between the interface ID and a user. As a result, the interface ID can be used as a unique identifier for the user. Accordingly, an effective infrastructure for individualized services is achieved. The interface ID may be constant for one user even when an apparatus is replaced, and thus IPv6 communication can be used as a user-associated address in high availability services, such as telephone services. Furthermore, the interface ID can be returned and reused, and thus the interface ID can be efficiently used.

A network system includes a plurality of communication nodes. In the network system, data transmitted from a server apparatus () is received by a PC () and a PDA (). Each of relay nodesobtains a communication network parameter concerning the communication network connecting the communication nodes with each other. Each of the relay nodes () also determines a communication route, based on a format conversion parameter concerning format of data transmitted from the server apparatus () and types of format conversion at format converters () and (), and the obtained communication network parameter.

A frame switching apparatus in which it is possible to suppress the operating frequency of the bus and to suppress the cell loss ratio in comparison with that of an ATM cell switching apparatus employing the conventional input buffer system. Since the small capacity buffer Bn-n furnishes a transient storage site for a cell C, a distribution circuit 3 is able to receive a new cell C from the input buffer 2 to process the received cell. Therefore, head-of-line blocking is less likely to take place. On the other hand, since the small capacity buffer transfers the cell to only one output port, it is sufficient if the switching matrix SWM is of a N:1 multiplexer structure which is far simpler than a complete cross-bandwidth available register structure.
