    • A router controls transmission of packets over a plurality of networks. The router has a function of carrying out address translation of addresses added to the packets between private addresses and global addresses. A plurality of interfaces are each connected to a corresponding one of the plurality of networks. A first storage device stores data for the address translation, the data being set by a user. A second storage device stores information for applying the data stored in the first storage device to each of the plurality of interfaces, the information being set by the user. A control device prepares translation management information for each of the plurality of interfaces, based on the data stored in the first storage device and the information stored in the second storage device. A translation device is arranged in each of the plurality of interfaces, for carrying out the address translation of one of the addresses added to each packet of the packets, based on the translation management information.
    • 路由器控制在多个网络上的分组的传输。 路由器具有在专用地址和全局地址之间进行地址转换的功能。 多个接口各自连接到多个网络中的对应的一个。 第一存储装置存储用于地址转换的数据,数据由用户设置。 第二存储装置存储用于将存储在第一存储装置中的数据应用于多个接口中的每一个的信息,该信息由用户设定。 控制装置基于存储在第一存储装置中的数据和存储在第二存储装置中的信息来准备多个界面中的每一个的翻译管理信息。 翻译装置布置在多个接口中的每一个中,用于基于翻译管理信息执行添加到分组的每个分组的地址之一的地址转换。

    • An optical disc reading device successively reads out data from an optical disc where the data are recorded on a packet-by-packet basis in such a manner that a link block is formed as a written-data gap between every adjoining packets. The data read out from the optical disc are decoded and subjected to an error detecting and correcting operation block by block. The blocks decoded and subjected to the error detecting and correcting operation are then sequentially stored into a data buffer. When a non-correctable error is found in a specific one of the blocks stored in the data buffer, the data reading section is controlled to continue the successive data readout from the optical disc if the specific block having the non-correctable error is a link block. But, if the specific block is not a link block, it is invalidated and the data reading section is controlled to stop the successive data readout from the optical disc. This arrangement effectively avoids degradation in reading performance even when an error occurs in a link block during advance readout of the data written on the packet-by-packet basis.
    • 光盘读取装置从光盘中连续地读出数据,其中数据被逐个分组地记录,使得链接块形成为每个邻接的分组之间的写入 - 数据间隙。 从光盘读出的数据被解码并逐块进行错误检测和校正操作。 解码并进行错误检测和校正操作的块然后被顺序地存储到数据缓冲器中。 当在存储在数据缓冲器中的特定块中发现不可校正的错误时,如果具有不可校正错误的特定块是链接,则控制数据读取部分以从光盘继续连续的数据读出 块。 但是,如果特定块不是链路块,则其被无效,并且数据读取部分被控制以停止从光盘读取连续的数据。 即使在以逐个分组为单位写入的数据的预先读出期间在链接块中发生错误时,这种布置也有效地避免了读取性能的降低。
