Packet Edit Processing Method and Related Device

摘要

A packet edit processing method and a device are provided. In an embodiment, the method includes: generating an input packet template based on N to-be-edited protocol header fields of an input packet, and a preset protocol field mapping relationship, where the input packet template includes N protocol descriptors, and the protocol field mapping relationship is a mapping relationship between a protocol field included in a protocol descriptor and a protocol field included in a protocol header field; performing edit processing on the input packet template to obtain an output packet template; and converting, based on the preset protocol field mapping relationship, M protocol descriptors into M protocol header fields of an output packet, and replacing the N protocol header fields in the input packet with the M protocol header fields to obtain the output packet.

1. A packet edit processing method, the method comprising:
generating an input packet template based on N to-be-edited protocol header fields of an input packet, and a preset protocol field mapping relationship, wherein the input packet template comprises N protocol descriptors that are corresponding, in a one-to-one manner, to the N protocol header fields, and the protocol field mapping relationship is a mapping relationship between a protocol field comprised in a protocol descriptor and a protocol field comprised in a protocol header field that has a correspondence with the protocol descriptor; performing edit processing on the input packet template to obtain an output packet template; and converting, based on the preset protocol field mapping relationship, M protocol descriptors comprised in the obtained output packet template into M protocol header fields of an output packet, and replacing the N protocol header fields in the input packet with the M protocol header fields to obtain the output packet, wherein N and M are positive integers.
