摘要:
A scheme for systematically registering meta-data with respect to various types of individual data so as to enable sophisticated retrieval or application program construction assistance utilizing the meta-data in a data server is disclosed. A data type of registering data to be registered into a data server that registers and manages data and meta-data for data, and one procedure corresponding to the detected data type is selected from a plurality of procedures provided in correspondence to respective data types and stored in advance, each procedure having a program code for generating the meta-data for data according to a corresponding data type. Then, the meta-data for the registering data are generated by executing the program code of the selected procedure, and the generated meta-data are registered in relation to the registering data.
摘要:
A method and an apparatus for controlling a continuous data server, capable of dealing with a fault in the control device without affecting operations of the continuous data server, by using a plurality of control devices. One control devices is operated as a master control device for actually controlling operations of the continuous data server, while at least one control device other than the master control device is operated as a slave control device for monitoring the master control device and taking over a function of the master control device when a fault is detected in the master control device.

摘要:
A node manages a virtual connection (VC) in a network such that at least one unused virtual connection to the neighboring node is established and registered. When a VC is needed to transmit a packet, the node obtains the required VC by selecting one of the registered unused VCs instead of setting up a new VC. When a VC in use becomes no longer necessary, the node registers the VC as an unused VC instead of releasing the VC.
