Slot interface access unit, method thereof, and program thereof, as well as redundancy configuration of main unit, and replacing method of the same

A slot interface access method carried out in a slot interface access unit comprising a slot management module, a slot control module, and a physical slot/managed slot comparison table between an input/output control module and a slot interface subordinate thereto, the method comprising:

• the input/output control module accessing the slot interface by using virtual slot identification information;
• and
• the slot management module referring to the physical slot/managed slot comparison table, converting the virtual slot identification information into physical slot identification information, and accessing a slot control module corresponding to the physical slot identification information obtained by the conversion, thereby realizing a physical access of the input/output control module to the slot interface,
• wherein the slot interface is architecturally lower than the input/output control module, and
• wherein the input/output control module is in a layer below an application layer of the slot interface access unit.

A slot interface access unit comprising a slot management module, a slot control module, and a physical slot/managed slot comparison table which are provided between an input/output control module and a slot interface subordinate thereto,

• wherein the input/output control module accesses the slot interface by using virtual slot identification information,
• the slot management module refers to the physical slot/managed slot comparison table, converts the virtual slot identification information into physical slot identification information, and accesses a slot control module corresponding to the physical slot identification information obtained by the conversion, thereby realizing a physical access of the input/output control module to the slot interface,
• wherein the slot interface access unit has a CPU power higher than that of other units having a slot interface,
• wherein the slot interface is architecturally lower than the input/output control module, and
• wherein the input/output control module is in a layer below an application layer of the slot interface access unit.
