Network performance measurement method, apparatus, device, and system, and storage medium

A network performance measurement apparatus applied to a first network device, wherein the network performance measurement apparatus comprises:

• a processor;
• and
• a transmitter coupled to the processor and configured to:
• send, to a second network device, a first active measurement protocol (AMP) packet, wherein the first AMP packet comprises measurement indication information that indicates a first measurement device on a forward path, wherein the forward path is a forwarding path of the first AMP packet, wherein the first network device is a first end of the forward path, wherein the second network device is a second end of the forward path, and wherein the first measurement device is an intermediate device on the forward path;
• and
• receive, after sending the first AMP packet, a second packet from the second network device, wherein the second packet is a reflected test packet of the first AMP packet and comprises reverse indication information, wherein the reverse indication information indicates a second measurement device on a reverse path for measuring network performance on the reverse path, wherein the second network device is a first end of the reverse path, and wherein the first network device is a second end of the reverse path, and wherein the second measurement device is a second intermediate device on the reverse path.

A network performance measurement system, comprising:

• a first network device configured to send, to a second network device, a first active measurement protocol (AMP) packet, wherein the first AMP packet comprises measurement indication information that indicates a first measurement device on a forward path, wherein the forward path is a forwarding path of the first AMP packet, wherein the first network device is a first end of the forward path, and wherein the first measurement device is an intermediate device on the forward path;
• a second network device coupled to the first network device, wherein the second network device is configured to:
• receive, from the first network device, the first AMP packet, wherein the second network device is a second end of the forward path, wherein the first AMP packet further comprises first measurement information obtained by the first measurement device on the forward path by measuring network performance of the forward path based on the measurement indication information;
• receive the first measurement information;
• and
• send, after receiving the first AMP packet, a second packet to the first network device, wherein the second packet is a reflected test packet of the first AMP packet and comprises reverse indication information, wherein the reverse indication information indicates a second measurement device on a reverse path for measuring network performance on the reverse path, wherein the second network device is a first end of the reverse path, and wherein the first network device is a second end of the reverse path, and wherein the second measurement device is a second intermediate device on the reverse path;
• and
• a third network device coupled to the first network device and to the second network device, wherein the third network device is a second intermediate device on the forward path, and wherein the third network device is configured to:
• receive the first AMP packet, wherein the first measurement device on the forward path comprises at least one intermediate device on the forward path and
• measure the network performance on the forward path based on the measurement indication information to obtain first measurement information;
• and
• send the first measurement information.
