Webb15 sep. 2009 · An adiabatic process (one which does not generate any heat) from state A to state B is therefore only possible if it is entropy increasing: S Θ (A) ≤ S Θ (B).. This definition, of thermodynamic entropy, depends upon cyclic processes that can reach the equality, which are called reversible processes. The existence of such processes … Webbthis difficulty: sampling and sketching. In sampling a subset of the incoming traffic is selected. It is the dominant approach currently, for example it is used in Cisco’s Netflow [1], which is based on a simple pseudo-random per-packet sampling scheme. Sustainable sampling rates are commonly quoted to be 1 in 256 packets. The
