Sampling Packets To Measure Network Performance

摘要

Disclosed are system, method, and computer-readable medium embodiments for a network to provide network applications and services and estimate network metrics for individual applications and services. In an embodiment, a first routing device receives a packet and determines that the packet is to be sampled. The first routing device samples the packet by storing first information associated with the packet and transmits the first information to a measurement server. The first routing device transmits the packet towards a destination according to routing information. A second routing device receives the packet and determines that the packet is to be sampled. The second routing device samples the packet by storing second information associated with the packet and transmitting the second information to the measurement server. The measurement server determines a measurement based on the first information and second information.

1. A method of measuring network performance comprising:
receiving a packet at a first routing device; determining, by the first routing device, that the packet is to be sampled; sampling, by the first routing device, the packet by storing first information associated with the packet; transmitting, by the first routing device, the first information to a measurement server; transmitting, by the first routing device, the packet towards a destination according to routing information; receiving the packet at a second routing device; determining, at the second routing device, that the packet is to be sampled; sampling, by the second routing device, the packet by storing second information associated with the packet; transmitting, by the second routing device, the second information to the measurement server; and determining, by the measurement server, a performance measurement based on the first information and second information.
