| Abstract: |
| Packet sampling measurement is a key technique in high-speed network traffic measurement and QoS monitoring. Starting with some basic principles of packet sampling , this paper first examines the significant mathematical conclusion of samlping strategies,then analyzes the current development of sampling technique after the comparison of strategies, mechanism and performance of different packet sampling methods. Especially it analyzes the latest development of packet sampling. Finally it expatiates the applications of packet sampling techniques in modern network measurement and monitoring. |
