They aim at achieving better performance than the estimation algorithm adopted by the Transfer Control Protocol (TCP) standard proposed in the late eighties. In general, the algorithms in the literature are assessed qualitatively, observing the estimation errors for a single connection scenario or via simulations. There are no works considering a quantitative evaluation metric, comparing the performance achieved by different algorithms. This motivates the present work in which several RTT estimation algorithms are compared using a common performance metric, and common experimental scenarios. As a second contribution, we propose an adaptive algorithm to estimate RTT, which is able to react quickly against sudden changes in the signal and, simultaneously, is less sensitive to noise interference than alternatives in the literature.</p>" ] ] "bibliografia" => array:2 [ "titulo" => "Referencias" "seccion" => array:1 [ 0 => array:2 [ "identificador" => "bibs0005" "bibliografiaReferencia" => array:33 [ 0 => array:3 [ "identificador" => "bib0005" "etiqueta" => "Anderson and Moore, 1979" "referencia" => array:1 [ 0 => array:1 [ "referenciaCompleta" => "Anderson, B.
