    • A technique for translating addresses in a communication network having multiple overlapping address domains involves mapping an overlapping local address from a first address domain to a unique global address that is specific to a second address domain. The unique global address is used by any device in the second address domain to reference the device in the first address domain having the overlapping local address. Furthermore, a packet sent from a source host in the first address domain to a destination host in the second address domain requires at least a source address translation in order to translate the source host local address used within the first address domain into a source host global address that is used within the second address domain, and may also require a destination address translation in order to translate the destination host global address used within the first address domain into a destination host local address used within the second address domain.
    • 用于翻译具有多个重叠地址域的通信网络中的地址的技术涉及将重叠的本地地址从第一地址域映射到特定于第二地址域的唯一全局地址。 唯一的全局地址由第二地址域中的任何设备用于引用具有重叠本地地址的第一地址域中的设备。 此外,从第一地址域中的源主机发送到第二地址域中的目的主机的分组至少需要源地址转换,以便将第一地址域内使用的源主机本地地址转换为源主机全局 地址,并且还可能需要目的地地址转换,以将第一地址域内使用的目的地主机全局地址转换为在第二地址域内使用的目的地主机本地地址。
