【摘要】：针对采用单一性能参数推测网络拓扑结构算法的问题,如有效性与网络负载有关以及测量节点性能参数时大多需要节点间时钟的同步等,在现有的测量方法基础上,提出了一种不需要节点间时钟同步可以测量端到端时延抖动和丢包相关性的紧接分组对序列测量方法,同时设计了一种综合端到端时延抖动和丢包相关性的双参数拓扑推测算法,该算法能够适应不同的网络负载环境。最后通过NS-2仿真实验验证了该算法的有效性和准确性。
[Abstract]:In order to solve the problem of using single performance parameter to estimate network topology algorithm, such as efficiency related to network load and synchronization of clock between nodes when measuring node performance parameters, the existing measurement methods are used to solve the problem. This paper proposes a method for measuring the sequence of back-to-back packet pairs without the need for clock synchronization between nodes to measure end-to-end delay jitter and packet loss correlation. At the same time, a two-parameter topology estimation algorithm combining end-to-end delay jitter and packet loss correlation is designed, which can adapt to different network load environments. Finally, the validity and accuracy of the algorithm are verified by NS-2 simulation.
