In-situ flow information telemetry method, encapsulation node, telemetry node, and computer-readable medium

A method of in-situ flow information telemetry for a telemetry node in a Multi-Protocol Label Switching (MPLS) network, the method comprising:

• parsing a label stack of a received MPLS packet;
• in response to the label stack comprising a telemetry indication label, determining a telemetry information label in the label stack based on the telemetry indication label, wherein the telemetry indication label is used to indicate the telemetry information label in the label stack, the telemetry information label is used to indicate a telemetry type and telemetry information of in-situ flow information telemetry to be performed;
• determining, based on the telemetry information label, a telemetry type and telemetry information of in-situ flow information telemetry to be performed;
• and
• performing the in-situ flow information telemetry based on the telemetry type and the telemetry information.

A telemetry node applied to a Multi-Protocol Label Switching (MPLS) network, comprising one or more memories and one or more processors, wherein the one or more memories store a computer program executable by the one or more processors causing implementation operations of in-situ flow information telemetry, comprising:

• parsing a label stack of a received MPLS packet;
• in response to the label stack comprising a telemetry indication label, determining a telemetry information label in the label stack based on the telemetry indication label, wherein the telemetry indication label is used to indicate the telemetry information label in the label stack, the telemetry information label is used to indicate a telemetry type and telemetry information of in-situ flow information telemetry to be performed;
• determining, based on the telemetry information label, a telemetry type and telemetry information of in-situ flow information telemetry to be performed;
• and
• performing the in-situ flow information telemetry based on the telemetry type and the telemetry information.
