Method and system for processing correction field information

A system for processing correction field information, comprising:

• a first correction value acquiring unit, adapted to receive a packet carrying correction field information, and obtain a first correction value contained in the correction field information;
• a first time acquiring unit, adapted to obtain first time information and second time information according to a time for the packet entering device, the first time information is nanosecond value information, the second time information is second value information;
• a second correction value acquiring unit, adapted to obtain a second correction value according to the first correction value and the first time information;
• a second correction value setting unit, adapted to update the first correction value in the correction field information to be the second correction value;
• a second time information setting unit, adapted to insert the second time information into the correction field information;
• a second time acquiring unit, adapted to obtain third time information and fourth time information according to a time for the packet exiting device, the third time information is nanosecond value information, the fourth time information is second value information;
• a third correction value acquiring unit, adapted to obtain a third correction value according to the second correction value, the second time information, the third time information, and the fourth time information;
• and
• a third correction value setting unit, adapted to update the second correction value in the correction field information to be the third correction value.
