Abstract: A service attribute management system is provided which is capable of automatically associating an appropriate attribute with a distributed object service without much labor and of providing consistency in attributes to be set. In the service attribute management system, attributes of distributed object services are stored in the service directory as management information, where attributes and its values are decided by an attribute setting section in accordance with some pre-defined rules.

Abstract: A service quality management system which is capable of adaptively controlling a quality of a service provided by a distributed object is provided. The system is provided with a first storage for saving information about a relation between a server for the distributed object and a priority set to services to be provided by the server and a second storage for saving information about a relation between an identifier for communication path under the control of a node and a priority set for processing made on the node. At the time of a request for activation of the server, the priority set to services provided by the server is read out by using priority reading from the first storage and the information about the identifier for communication path corresponding to processing with the same priority as that read from the priority reading device is read out by using an identifier reading device from the second storage.
