    • 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.
    • 发送端终端装置经由发送端路由器将包含视频数据等大尺寸数据的电子邮件发送给发送端缓存。 发送端缓存临时存储接收到的数据。 POB服务器认证发送终端设备的用户,并确定接收终端设备是否可以接收电子邮件。 如果用户的认证成功,并且如果确定接收终端设备可以接收电子邮件,则发送端缓存将电子邮件直接发送到接收端缓存,而不通过POB服务器。 接收端缓存存储所接收的电子邮件,并向接收端终端装置发送指示电子邮件已经到达的消息。 响应于接收终端装置发出的请求,接收端​​缓存将存储在其中的电子邮件提供给接收端终端装置。

    • 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.
    • 提供了一种缓存设备和用于控制高速存储区域的高速缓存数据的控制方法,提高了命中率。 当在通过网络彼此连接的高速缓存设备中执行高速缓存替换时,执行数据控制,使得在每个高速缓存设备中设置为删除等待状态的数据块包括关于设置为删除挂起状态的数据块的列表, 在高速缓存组中与缓存组中的其他高速缓存设备不同。 以这种方式,执行使用删除挂单的数据控制。 根据本发明的系统,与每个高速缓存设备独立地控制高速缓存替换的情况相比,可以有效地使用存储区域,并且收集存储在多个高速缓存设备中的数据块以响应于 来自终端的数据采集请求,从而促进网络流量并提高缓存设备的命中率。
