Abstract

An information processing device is provided that includes a receiver to receive information from another information processing device that mutually communicates the information and a processor to process the information received by the receiver. The receiver detects occurrence of a burst error in the received information, sequentially writes the received information in a first memory, stops the writing of the information to the first memory based on detection of the burst error, shuts off transmission of the information received from the another information processing device based on a reproducing instruction, and transmits the information read from the first memory.

Claims (82)

1. An information processing device comprising:

a receiver configured to receive information from another information processing device; and

a processor configured to process received information received by the receiver,

the receiver:

detects occurrence of a burst error in the received information;

writes the received information in a first memory;

stops the writing of the received information to the first memory based on detection of the burst error;

shuts off transmission of the received information based on a reproducing instruction;

reads the written information from the first memory; and

transmits the read information, wherein

the burst error is an error state in which the bit error rate exceeds a certain threshold.

2. The information processing device according to claim 1 , wherein

the receiver:

reads the written information including the burst error from the first memory based on a first reproducing instruction of the reproducing instruction;

shuts off transmission of the received information to an internal transmission line within the information processing device based on a second reproducing instruction of the reproducing instruction; and

couples the read information to the internal transmission line.

3. The information processing device according to claim 2 , wherein

the receiver:

stores, in a second memory, positional information indicating a position of a storage area storing oldest information in the first memory; and

reads the written information in the first memory from the storage area indicated by the positional information stored in the second memory.

4. The information processing device according to claim 2 , wherein

a transmission rate at which the read information is output to the internal transmission line is equal to a transmission rate of the information from the another information processing device.

5. The information processing device according to claim 2 , wherein

the receiver:

shuts off transmission of the read information to the internal transmission line and couples the path through which the received information from the another information processing device to the internal transmission line based on a return instruction; and

releases a stopped state of writing the received information to the first memory based on a release instruction.

6. The information processing device according to claim 5 , wherein

the first reproducing instruction, the second reproducing instruction, the return instruction, or the release instruction is generated based on a request from a management device.

7. The information processing device according to claim 1 , wherein

the receiver:

checks the received information from the another information processing device;

outputs error detection information each time an error is detected;

counts a number of outputs of the error detection information;

reads a counter value at a first time interval,

calculates an increase rate of the counter value; and

detects the occurrence of the burst error when the calculated increase rate exceeds a first threshold value.

8. The information processing device according to claim 7 , wherein

the receiver:

rewritably retains the first time interval and the first threshold value in a second memory; and

detects the occurrence of the burst error based on the first time interval and the first threshold value, and

the first memory has a storage capacity capable of writing the received information from the another information processing device within a maximum first time interval that is settable in the second memory.

9. The information processing device according to claim 1 , wherein

the receiver:

receives the received information from the another information processing device as packets; and

sequentially writes the received packets to the first memory.

10. A burst error producing method comprising:

receiving information from another information processing device; and

detecting, by a computer, occurrence of a burst error in the received information;

writing the received information in a first memory;

stopping the writing of the received information to the first memory based on detection of the burst error;

shutting off transmission of the received information based on a reproducing instruction;

reading the written information from the first memory; and

transmitting the read information, wherein

the burst error is an error state in which the bit error rate exceeds a certain threshold.

11. The burst error producing method according to claim 10 , further comprising:

reading the written information including the burst error from the first memory based on a first reproducing instruction of the reproducing instruction;

shutting off transmission of the received information to an internal transmission line within the information processing device based on a second reproducing instruction of the reproducing instruction; and

coupling the read information to the internal transmission line.

12. The burst error producing method according to claim 11 , further comprising:

storing, in a second memory, positional information indicating a position of a storage area storing oldest information in the first memory; and

reading the written information in the first memory from the storage area indicated by the positional information stored in the second memory.

13. The burst error producing method according to claim 11 , wherein

a transmission rate at which the read information is output to the internal transmission line is equal to a transmission rate of the information from the another information processing device.

14. The burst error producing method according to claim 11 , further comprising:

shutting off transmission of the read information to the internal transmission line and couples the path through which the received information from the another information processing device to the internal transmission line based on a return instruction; and

releasing a stopped state of writing the received information to the first memory based on a release instruction.

15. The burst error producing method according to claim 14 , wherein

the first reproducing instruction, the second reproducing instruction, the return instruction, or the release instruction is generated based on a request from a management device.

16. The burst error producing method according to claim 10 , further comprising:

checking the received information from the another information processing device;

outputting error detection information each time an error is detected;

counting a number of outputs of the error detection information;

reading a counter value at a first time interval,

calculating an increase rate of the counter value; and

detecting the occurrence of the burst error when the calculated increase rate exceeds a first threshold value.

17. The burst error producing method according to claim 16 , further comprising:

rewritably retaining the first time interval and the first threshold value in a second memory; and

detecting the occurrence of the burst error based on the first time interval and the first threshold value, and

the first memory has a storage capacity capable of writing the received information from the another information processing device within a maximum first time interval that is settable in the second memory.

18. The burst error producing method according to claim 10 , further comprising:

receiving the received information from the another information processing device as packets; and

sequentially writing the received packets to the first memory.
