数据流测量的非对称主备切换机制
Asymmetrical Primary-standby Switching Mechanism for Data Flow Measurement
摘要
Abstract
The Symmetrical Primary Standby Switching(SPSS) mechanism employed by existing flow traffic measurement algorithms can not make full use of memory space. An Asymmetrical Primary Standby Switching(APSS) mechanism is presented for improving the space efficiency of data flow measurement algorithms. The APSS mechanism is based on the observations that flow arrival process is stable, and DRAM can support bulk write which is much faster than random access. A small standby memory is enough to realize the primary-standby mechanism. Experimental results show that compared with SPSS, APSS can reduce memory consumption by almost a half while having trivial impact on the measurement error probability.关键词
