In a specific application scenario, fig. 3 is a schematic diagram showing a sample format of a first padding replacement control sequence, i.e., a first control byte in the diagram, in which padding characters, i.e., padding values, are removed to compress a message, the first padding replacement control sequence is shown as a single byte with 8 bits, which is very consistent with the current CORBA GIOP protocol, and other sequence lengths are also applicable thereto.
The first bit (0) of the first padding replacement control sequence is set to '0' and represents the GIOP message as including compression based on the padding value, and the remaining 7 bits (1-7) of the first padding replacement control sequence store an index to the first sequential padding replacement control sequence, i.e., an index of a next sequential padding replacement control sequence set by other bits in the first padding replacement control sequence, which is formatted as shown in fig. 3, and in the case where the first padding replacement control sequence has a length of 8 bits, the index may have a value between 0 and 127.

For example, bytes 1-3,5-7,9-B and D-F in the first row (row 0) are all "0".
Fig. 6 is a schematic diagram showing a format of a GIOP message compressed by the first compression method, in which a first padding replacement control sequence and a plurality of sequential padding replacement control sequences replace a padding value "0" in an uncompressed GIOP message, the first padding replacement control sequence being located in a first byte (0) of the compressed message, the first padding replacement control sequence having a binary-coded decimal value and a hexadecimal value equal to 2, the first padding replacement control sequence being identified in the diagram by a letter "fcb" in the first byte (0) of the compressed GIOP message, the decimal value being recorded in a top row of cells identifying corresponding bytes of the GIOP message, and the hexadecimal value being recorded in a second row of the cells and beginning with the letter "x", the decimal value 2 and the hexadecimal value 02 representing a bit string: "00000010", referring to the format shown in fig. 2, the first bit (0) represents the first padding control sequence and the remaining 7 bits (1-7) identify the index of the next sequential padding replacement control sequence, in this case, the index is equal to 2, and therefore the next sequential padding replacement control sequence is two bytes from the first replacement padding control sequence, occurring at the third byte (2) of the compressed GIOP message.
The sequential fill replacement control sequence has a decimal value 98 and a hexadecimal value 62 and is represented by the character string "scb", the decimal value 98 and the hexadecimal value 62 representing a bit string: "0110010", referring to fig. 3, the first three bits "011" correspond to the length of the padding sequence, and the remaining 5 bits "00010" correspond to the index of the next sequential padding replacement control sequence, so that the padding sequence has a length of 3 and the index to the next sequential padding replacement control sequence is equal to 2, confirming with reference to fig. 4 that the first padding sequence has a length of 3.
The terminal can easily identify the remaining sequential padding replacement sequences from the letter "scb" identifying the cell length of the compressed GIOP message bytes, the final sequential padding replacement control sequence is displayed at byte 61 (line 48, column C) with a decimal value of 96 and a hexadecimal value of 60, the decimal value 96 and the hexadecimal value 60 representing the bit string "01100000", the first three bits "011" of the bit string identifying the length of the padding sequence equal to 3, the last 5 bits "00000" identifying the index equal to 0, identifying that there is no further sequential padding replacement control sequence in the compressed GIOP message.
