Packet modification method and apparatus, computer device, and storage medium

A packet modification apparatus, comprising:

• a dividing module configured to divide a field to be modified that is related to packet encapsulation information into M containers;
• an extraction module configured to perform instruction extraction on a very long instruction word executing a modification command, to obtain N groups of initial instructions, where 2≤N≤M;
• a processing module configured to process the N groups of initial instructions to obtain N groups of source operands and N groups of modification field configuration information;
• a determining module configured to determine, according to the N groups of modification field configuration information, N containers matched with the N groups of source operands, respectively;
• and
• a modification module configured to modify, according to the N groups of source operands, the N matched containers, respectively.
