Jie Xu, Wei Ding, Xiaoyan Hu

摘要:

超级主持人是一种特殊的主持人,是一种能够与众多的主持人进行交流的主持人。网络边缘超点挖掘是网络研究的基础。本文提出了一种存储效率最高的超点检测方案。该方案包括一个超点重建算法(短估计器)和一个超点滤波算法(长估计器)。短估计器使用数千字节的存储器给出超级点候选列表,长估计器使用数百万字节的存储器提高检测结果的准确性。结合短估计器和长估计器,我们的方案获得了最高的精度,使用最小的内存比其他算法。在我们的方案中没有数据冲突和浮动操作。这确保了我们的方案适合并行运行,我们将我们的方案部署在一个共同的GPU上,以加快处理速度。我们还描述了如何将我们的算法扩展到滑动时间。在几个真实的核心网络流量上的实验表明,该算法仅占用其他算法的五分之一的内存,就获得了最高的准确率。

英文摘要:

The super point, a host which communicates with lots of others, is a kind of special hosts gotten great focus. Mining super point at the edge of a network is the foundation of many network research fields. In this paper, we proposed the most memory efficient super points detection scheme. This scheme contains a super points reconstruction algorithm called short estimator and a super points filter algorithm called long estimator. Short estimator gives a super points candidate list using thousands of bytes memory and long estimator improves the accuracy of detection result using millions of bytes memory. Combining short estimator and long estimator, our scheme acquires the highest accuracy using the smallest memory than other algorithms. There is no data conflict and floating operation in our scheme. This ensures that our scheme is suitable for parallel running and we deploy our scheme on a common GPU to accelerate processing speed. We also describe how to extend our algorithm to sliding time. Experiments on several real-world core network traffics show that our algorithm acquires the highest accuracy with only consuming littler than one-fifth memory of other algorithms.
