The following uses several examples to illustrate how to modify business data.

Assume that the corresponding modification methods for the five service data (data a~data e) in service 1 are pre-configured in the router (of course, the same modification method can also be configured for more than two of the data). The backed up business data, original business data format, new business data format and modification methods are as follows:

Business 1 Data a

{

1,

2

};

The corresponding original data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2

};

The modification method is:

new data1 = old data1

new data2 = old data2

new data3 = 0

Then the new data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2,

Int (4 bytes) data3

};

Business 1 data b

{

4,

5,

6

};

The corresponding original data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2,

Int (4 bytes) data3

};

The modification method is:

new data1 = old data1

new data2 = old data2

Then the new data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2,

};

Business 1 Data c

{0x01, 0x00, 0x5e, 0x01, 0x01, 0x01}

The corresponding original data format is:

Char (6 bytes) data1

The modification method is: copy the last 4 bytes of old data1 to new data1;

Then the new data format is:

Int (4 bytes) data1

business 1 data d

0x01020304,

The corresponding original data format is:

int (4 bytes) data1,

The modification method is: copy the first 4 bytes of the old data1 to the last four bytes of the new data1;

Then the new data format is:

Char (6 bytes) data1

Business 1 data e

{

0x01010101,

0x02020202

};

The corresponding original data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2

}

The modification method is:

new data1 = old data2

new data2 = old data1

Then the new data format is:

{

Int (4 bytes) data1,

Int (4 bytes) data2

}

From the above example, it can be seen that in the service data backed up in the router and the modification method of the configuration, the description of the format of each service data should define fields with type and length.

On the other hand, several operations are defined in the modification method, such as assignment, copying the first/last n bytes of the old data to the first/last n bytes of the new data, changing the order of the old and new data, etc.; way to perform these operations.
