Abstract

An information processing system according to the present invention includes: a plurality of processing units; a plurality of input/output units controlled by any one of the processing units; a plurality of first connection units connecting one of the processing units to a first communication channel; a second connection unit connecting the input/output units to a second communication channel; a first mediating unit mediating the second communication channel and a communication network, and transmits identifiers of the input/output units via the communication network; and a plurality of second mediating units mediating a connection between the communication network and the first communication channel, receiving the identifier, and, when an identifier of its own is included in the received identifiers, establishing a connection between the input/output unit with the own identifier and the processing unit and detaches connections between the input/output unit with different identifier and the processing unit.

First claim

What is claimed is:

1. An information processing system comprising:
a plurality of processing units which perform predetermined processing;
a plurality of input/output units, each of which performs input and/or output processing under the control of any one of the processing units;
a plurality of first connection units, each of which connects one of the processing units to a first communication channel corresponding to the processing unit;
a second connection unit which connects the plurality of input/output units to a second communication channel;
a first mediating unit which mediates the second communication channel and a communication network, and transmits identifiers of the plurality of input/output units via the communication network; and
a plurality of second mediating units, each of which respectively mediates a connection between the communication network and the first communication channel, receives the identifier transmitted to the communication network, and, when an identifier of the second mediating unit is included in the received identifiers, establishes a connection between the input/output unit corresponding to the identifier of the second mediating unit and the processing unit via the first mediating unit and detaches connections between the input/output unit corresponding to identifier different from the identifier of the second mediating unit and the processing unit.

2. The information processing system according to claim 1 ,
wherein the first communication channel is a communication channel of the same specification as the second communication channel.

3. The information processing system according to claim 1 ,
wherein the first mediating unit transmits identifiers which are changed by changes in connections of the plurality of input/output units to the communication network; and
the second mediating unit receives the changed identifiers via the communication network, and, when the received identifiers do not include an identifier of its own, detaches the connection between the input/output unit corresponding to the identifier of its own and the processing unit.

4. The information processing system according to claim 3 ,
wherein the second mediating unit, when the received identifiers being changed include an identifier of its own and the second mediating unit has not established a connection between the input/output unit and the processing unit corresponding to the identifier of its own, establishes a connection between the input/output unit and the processing unit corresponding to the identifier of its own.

5. The information processing system according to claim 1 , further comprising:
a management unit which notifies the first mediating unit of the identifiers of the plurality of input/output units.

6. The information processing system according to claim 5 , further comprising:
a third connection unit which connects the management unit to a third communication channel; and
a third mediating unit which mediates a connection between the third communication channel and the communication network.

7. An information processing method for an information processing system, the system comprising:
a plurality of processing units which perform predetermined processing;
a plurality of input/output units, each of which performs input and/or output processing under the control of any one of the processing units;
a plurality of first connection units, each of which connects one of the processing units to a first communication channel corresponding to the processing unit;
a second connection unit which connects the plurality of input/output units to a second communication channel;
a first mediating unit which mediates a connection between the second communication channel and a communication network; and
a plurality of second mediating unit, each of which respectively mediates a connection between the communication network and the first communication channel,
the method comprising:
by the first mediating unit, transmitting identifiers of the plurality of input/output units via the communication network; and
by the second mediating unit, receiving the identifiers transmitted to the communication network, and, when an identifier of the second mediating unit is included in the received identifiers, establishing a connection between the input/output unit and the processing unit corresponding to the second mediating unit identifier via the first mediating unit and detaching connections between the input/output unit corresponding to identifier different from the identifier of the second mediating unit and the processing unit.

8. A computer readable non-transitory recording medium embodying a program, the program causing an information processing system to perform a method, the system comprising:
a plurality of processing units which perform predetermined processing;
a plurality of input/output units, each of which performs input and/or output processing under the control of any one of the processing units;
a plurality of first connection units, each of which connects one of the processing units to a first communication channel corresponding to the processing unit;
a second connection unit which connects the plurality of input/output units to a second communication channel;
a first mediating unit which mediates a connection between the second communication channel and a communication network; and
a plurality of second mediating unit, each of which respectively mediates a connection between the communication network and the first communication channel,
the method comprising:
by the computer as the first mediating unit, transmitting identifiers of the plurality of input/output units via the communication network; and
by the computer as the second mediating unit, receiving the identifiers transmitted to the communication network, and, when an identifier of the second mediating unit is included in the received identifiers, establish a connection between the input/output unit corresponding to the second mediating unit identifier and the processing unit via the first mediating unit and detach connections between the input/output unit corresponding to identifier different from the identifier of the second mediating unit and the processing unit.
