Abstract: A cache device and a method for controlling cached data that enable efficient use of a storage area and improve the hit ratio are provided. When cache replacement is carried out in cache devices connected to each other through networks, data control is carried out so that data blocks set to a deletion pending status in each cache device, which includes lists regarding the data blocks set to a deletion pending status, in a cache group are different from those in other cache devices in the cache group. In this way, data control using deletion pending lists is carried out. According to the system of the present invention, a storage area can be used efficiently as compared with a case where each cache device independently controls cache replacement, and data blocks stored in a number of cache devices are collected to be sent to terminals in response to data acquisition requests from the terminals, thereby facilitating network traffic and improving the hit rate of the cache devices.

Abstract: A transmitting-end terminal device transmits an electronic mail including large-size data such as video data to a transmitting-end cache via a transmitting-end router. The transmitting-end cache temporarily stores the received data. A POB server authenticates a user of the transmitting-end terminal device and determines whether a receiving-end terminal device can receive the electronic mail. If the authentication of the user is successful and if it is determined that receiving-end terminal device can receive the electronic mail, the transmitting-end cache transmits the electronic mail directly to the receiving-end cache without passing it through the POB server. The receiving-end cache stores the received electronic mail and transmits a message, indicating that the electronic mail has arrived, to the receiving-end terminal device. In response to a request issued by the receiving-end terminal device, the receiving-end cache supplies the electronic mail stored therein to the receiving-end terminal device.

Abstract: In an improved address management system using portable storage media, an anycast address is supplied via a portable storage medium so that the anycast address can be used by various communication terminals. When a communication terminal is replaced with a new one, the same anycast address can be used for the new communication terminal, and thus IPv6-based communication can be employed in a service such as telephone service in which high availability is required. Furthermore, an anycast address can be used as an identifier uniquely identifying a user. Thus, this technique provides an infrastructure which is very useful, in particular, in applications in which service is provided differently depending on customers. Furthermore, an anycast address can be moved, copied, and returned. This makes it possible for a number of users or devices to use the same anycast address in a very efficient manner.
