Abstract

The application provides an operation request generating method. The method includes: a generation device generates a first operation request that requests to perform an operation on a first packet, where the first operation request includes first assignment content and information used to indicate a first assignment location, the first assignment location is a location in the first packet, the first assignment content is data used to assign a value to the first assignment location, and the information used to indicate the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, where the first packet header is a packet header in the first packet, and the first offset is an offset relative to a start location of the first packet header; and the generation device sends the first operation request to a description device or a receiving device.

Claims13

Dependent claims

An operation request generating method, the method comprising:

receiving, by a description device, a first operation request that requests performance of an operation on a first packet, wherein the first operation request includes first assignment content and information indicating a first assignment location, wherein the first assignment location is a location in the first packet, wherein the first assignment content is data used to assign a value to the first assignment location, wherein the information indicating the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, wherein the first packet header is a packet header in the first packet, wherein the type of the first packet header is indicated by an identifier of the type of the first packet header, wherein a first field corresponding to the first assignment location is indicated by an identifier of the first field associated with a format of the first packet header, the first offset, and the first length, wherein the first field is a field in the first packet header, and wherein the format of the first packet header is indicated by the type of the first packet header, and wherein the first offset is an offset relative to a start location of the first packet header;
obtaining, by the description device, a second operation request according to the first operation request, wherein the second operation request is described in a first description language recognizable to a receiving device, wherein the first operation request is not described in the first description language, and wherein the second operation request requests the performance of the operation on the first packet;
and
sending the second operation request to the receiving device.

1 more element

A packet processing method, the method comprising:

receiving, by a receiving device, a first operation request that requests performance of an operation on a first packet, wherein the first operation request includes first assignment content and information indicating a first assignment location, wherein the first assignment location is a location in the first packet, wherein the first assignment content is data assigning a value to the first assignment location, and wherein the first operation request is described in a first description language recognizable to the receiving device;
and
determining, by the receiving device according to the information indicating the first assignment location, an identifier of a first field corresponding to the first assignment location, wherein the information indicating the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, wherein the first packet header is a packet header in the first packet, and wherein the first offset is an offset relative to a start location of the first packet header, and wherein the determining the identifier of the first field corresponding to the first assignment location comprises:
determining the type of the first packet header according to the identifier of the type of the first packet header;
and
determining the identifier of the first field according to a format of the first packet header, the first offset, and the first length, wherein the first field is a field in the first packet header, and wherein the format of the first packet header is determined according to the type of the first packet header.

3 more elements

A receiving device, comprising:

a receiving port configured to receive a first operation request that requests performance of an operation on a first packet, wherein the first operation request comprises first assignment content and information indicating a first assignment location, wherein the first assignment location is a location in the first packet, and the first assignment content is data used to assign a value to the first assignment location, wherein the first operation request is described in a first description language recognizable to the receiving device;
a processor connected to the receiving port;
and
a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed by the processor, cause the receiving device to:
determine, according to the information indicating the first assignment location, an identifier of a first field corresponding to the first assignment location, wherein the information indicating the first assignment location includes an identifier of a type of a first packet header, a first offset, and a first length, wherein the first packet header is a packet header in the first packet, and wherein the first offset is an offset relative to a start location of the first packet header, and wherein the instructions to determine the identifier of the first field corresponding to the first assignment location comprises instructions to cause the receiving device to:
determine the type of the first packet header according to the identifier of the type of the first packet header;
and
determine the identifier of the first field according to a format of the first packet header, the first offset, and the first length, wherein the first field is a field in the first packet header, and wherein the format of the first packet header is determined according to the type of the first packet header.
