| 摘要 | A communication apparatus for carrying out communications to and from an external apparatus that includes a first interconnecting unit and a first non-transparent port and effects an interconnection for communications via the first non-transparent port is provided. The communication apparatus includes a second interconnecting unit that includes a second non-transparent port communicably connected to the first non-transparent port. The second interconnecting unit effects an interconnection for communications via the second non-transparent port. The second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port. | ||

| 主权项 | 1. A communication apparatus for carrying out communications to and from an external apparatus, the external apparatus including a first interconnecting unit having a first non-transparent port and effecting an interconnection for communications via the first non-transparent port, the communication apparatus comprising: a second interconnecting unit including a second non-transparent port communicably connected to the first non-transparent port, the second interconnecting unit effecting an interconnection for communications via the second non-transparent port, wherein the second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus via the second non-transparent port, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port, and wherein when the communication apparatus carries out communications to and from the external apparatus via the second non-transparent port, the address for use by the communication apparatus is translated into the address for use by the second non-transparent port, which is a first address in an address space in common with the first non-transparent port and the second non-transparent port, and an address for use by the external apparatus is translated into a second address in the address space in common with the first non-transparent port and the second non-transparent port. | ||
