Abstract
This application provides an example delay measurement method and an example network device. The method includes receiving, by a first network device, a first service flow. The method also includes determining, by the first network device, a first delay value based on a first measurement code block in the first service flow. The first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device.

A delay measurement method, comprising:
- receiving, by a first network device, a first service flow;
- determining, by the first network device, a first delay value based on a first measurement code block in the first service flow, wherein the first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device;
- receiving, by the first network device, a second service flow, wherein a transmission direction of the second service flow is opposite to a transmission direction of the first service flow, and the second service flow and the first service flow belong to a same service;
- and
- determining, by the first network device, a second delay value based on a second measurement code block in the second service flow, wherein the second delay value is a time difference between a third moment at which the second measurement code block is detected in the first network device and a fourth moment at which the second measurement code block is detected in the first network device.
A network device, wherein the network device is a first network device and comprises:
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to:
- receive a first service flow;
- determine a first delay value based on a first measurement code block in the first service flow, wherein the first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device;
- receive a second service flow, wherein a transmission direction of the second service flow is opposite to a transmission direction of the first service flow, and the second service flow and the first service flow belong to a same service;
- and
- determine a second delay value based on a second measurement code block in the second service flow, wherein the second delay value is a time difference between a third moment at which the second measurement code block is detected in the first network device and a fourth moment at which the second measurement code block is detected in the first network device.
A non-transitory computer-readable medium storing computer instructions that, when executed by one or more processors, cause a computer to perform operations comprising:
- receiving, by a first network device, a first service flow;
- determining, by the first network device, a first delay value based on a first measurement code block in the first service flow, wherein the first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device;
- receiving, by the first network device, a second service flow, wherein a transmission direction of the second service flow is opposite to a transmission direction of the first service flow, and the second service flow and the first service flow belong to a same service;
- and
- determining, by the first network device, a second delay value based on a second measurement code block in the second service flow, wherein the second delay value is a time difference between a third moment at which the second measurement code block is detected in the first network device and a fourth moment at which the second measurement code block is detected in the first network device.
