摘要: Under the assumption that packets are sufficiently interleaved and sampling rate is small, we show in this paper those characteristics of flows like number packets, volume, etc. obtained through deterministic 1-out-of-k packet equivalent to random with p = 1/k. In particular, under mild assumptions, tail distribution total a given flow can be estimated from sampled packets. Explicit theoretical bounds then derived by using technical tools relying on Poisson approximation (Le Cam's Inequality) refinements central limit theorem (Berry-Essen bounds). Experimental results an ADSL traffic trace good agreement established paper.
