| 英文摘要 | DPDK burst-oriented packet processing boosts up the performance of packet capture at the cost of packet timestamp accuracy. Being blind to packet timestamp deviates from the goal of monitoring since it has a significant effort on network traffic monitoring and analysis. In this paper, we analyze packet timestamp of DPDK burstoriented packet processing and model the cumulative time gaps of packet timestamp in the same burst. Then, we demonstrate that timestamping packet in a 1-by-1 fashion after acquiring system time is not suitable for DPDK as the cumulative time gaps depending on packets number in a burst and subsequent operations on each packet make it uncontrollable. At last, a packet length aware timestamping mechanism is proposed and demonstrated that it can conform to the theoretical model we give. Experiments show the rationality and effectiveness of our proposed timestamping mechanism. |
