Abstract

A control method to be executed by a processor included in a transmission apparatus, the control method includes receiving, from a first interface device storing first circuit data, a first version of the first circuit data at a time of coupling of the first interface device to the transmission apparatus; extracting, from a plurality of interface devices included in the transmission apparatus, second circuit data of a second interface device storing the second circuit data, where a second interface device type is a same as a first interface device type, when the second interface device exists in the plurality of interface devices and when the first version matches a second version stored in a memory, the second version being associated with the second interface device type of the second version stored in the memory; and copying the second circuit data to the first interface device.

First claim

What is claimed is:

1. A control method to be executed by a processor included in a transmission apparatus, the control method comprising:
receiving, from a first interface device storing first circuit data, a first version of the first circuit data at a time of coupling of the first interface device to the transmission apparatus;
extracting, from a plurality of interface devices included in the transmission apparatus, second circuit data of a second interface device storing the second circuit data, where a second interface device type is a same as a first interface device type, when the second interface device exists in the plurality of interface devices and when the first version matches a second version stored in a memory, the second version being associated with the second interface device type of the second version stored in the memory; and
copying the second circuit data to the first interface device.

2. The control method according to claim 1 , further comprising:
receiving, from a computer coupled to the transmission apparatus, third circuit data corresponding to the first interface device when the second interface device does not exist in the plurality of interface devices; and
copying the third circuit data to the first interface device.

3. The control method according to claim 2 , further comprising:
requesting the computer to transmit the third circuit data corresponding to the first interface device when the second interface device does not exist in the plurality of interface devices.

4. The control method according to claim 2 , wherein
the receiving of the third circuit data includes receiving, from a data center that stores circuit data for the first interface device and each of the plurality of interface devices, the third circuit data corresponding to the first interface device.

5. The control method according to claim 1 , further comprising:
conducting a reconfiguration of a field programmable gate array in the first interface device based on the second circuit data.

6. The control method according to claim 1 , further comprising:
storing information of the first interface device type and the first version associated with each other in the memory.

7. The control method according to claim 6 , further comprising:
deleting the information of the first interface device type and the first version stored in the memory when the first interface device is decoupled from the transmission apparatus.

8. The control method according to claim 1 , wherein
the copying of the second circuit data includes copying the second circuit data to a first region of the first interface device; and
the control method further comprises:
extracting, from the plurality of interface devices except for the second interface device, a third interface device based on a slot number of the first interface device; and
copying fourth circuit data of the third interface device to a second region of the first interface device.

9. The control method according to claim 8 , wherein
the extracting of the third interface device includes extracting the third interface device coupled to a slot with another number next to the slot number of the first interface device in ascending order.

10. The control method according to claim 9 , further comprising:
updating the second region of a fourth interface device coupled to a further slot with a further number next to the slot number of the first interface device in descending order, when the first interface device is decoupled from the transmission apparatus.

11. A transmission apparatus, comprising:
a memory, and
a processor coupled to the memory and configured to:
receive, from the first interface device storing first circuit data, a first version of the first circuit data at a time of coupling of the first interface device to the transmission apparatus;
extract, from a plurality of interface devices included in the transmission apparatus, second circuit data of a second interface device storing the second circuit data, where a second interface type is a same as a first interface device type, when the second interface device exists in the plurality of interface devices and when the first version matches a second version stored in a memory, the second version being associated with the second interface device type of the second version stored in the memory; and
copy the second circuit data of the second interface device to the first interface device.

12. A computer-readable non-transitory recording medium storing a program causing a computer to execute a process, the process comprising:
receiving, from a first interface device storing first circuit data, a first version of the first circuit data at a time of coupling of the first interface device to the transmission apparatus;
extracting, from a plurality of interface devices included in the transmission apparatus, second circuit data of a second interface device storing the second circuit data, where a second interface device type is a same as a first interface device type, when the second interface device exists in the plurality of interface devices and when the first version matches a second version stored in a memory, the second version being associated with the second interface device type of the second version stored in the memory; and
copying the second circuit data to the first interface device.
