For the limit of false positives probability in Bloom Filter (BF), this paper proposed a novel mechanism based on Hierarchy Bloom Filter (HBF) for recording network flows statistic. By extending the standard structure of Bloom Filter to multi-layer with the false positives probability which predefined each layer, the mechanism could not only record more flows, but also adapt dynamically when the number...
Identifying elephant flows is very important in developing effective and efficient traffic engineering schemes. In this paper, according to the characteristic of network flows, an algorithm based on multiple filters is proposed to realize elephant flows identification. Multiple filters algorithm improves the performance and saves the storage from three aspects: large flows handled firstly, using Timeout-Counting...
Identifying elephant flows is very important in developing effective and efficient traffic engineering schemes. In this paper, according to the characteristic of network flows, a new packet filtering technique is proposed to realize elephant flows identification. The algorithm is combined by Time-out Bloom filter and Counting Bloom Filter, where TBF filtrate small flows and CBF record large flows...
