“…En [74], los autores presentaron un estudio de simulación, de la influencia de un método de multiplexión en los parámetros que definen la calidad subjetiva de los juegos online (principalmente retardo, jitter y pérdida de paquetes). Los resultados muestran que los buffer pequeños, presentan mejores características para mantener el retardo y el jitter en valores adecuados, pero a costa de incrementar la pérdida de paquetes.…”

“…As a counterpart of the savings, a small multiplexing delay is required in order to get a number of packets to be sent together. This delay will vary between 0 and the multiplexing period PE, with an average value of PE/2 [6].…”

This paper explores the application of traffic optimization techniques, based on header compression and multiplexing, to the flow of ACKs sent by a TCP client when downloading a file. Significant compression rates can be obtained, but a multiplexing delay has to be added as a counterpart. The influence of this delay in TCP dynamics is explored by means of simulations including FTP flows sharing a bottleneck. The results show that the impairments can be maintained in reasonable limits, by selecting proper values of the multiplexing period. Thus, the multiplexing of these ACK flows can be further studied and considered as a possibility for traffic optimization.

“…In [13] the authors present study of the influence of a multiplexing method on the parameters that define the subjective quality of online games: mainly delay, jitter and packet loss. The work considers two buffer implementations, each one with two buffer sizes, in order to study the relationship between router's buffer and multiplexing on subjective quality.…”

The behaviour of the routers' buffer is of primary importance when studying network traffic, since it may modify some characteristics, as delay or jitter, and may also drop packets. As a consequence, the characterization of this buffer is interesting, especially when real-time flows of interactive services are being transmitted. If the buffer characteristics are known, then different techniques can be used so as to adapt the traffic: multiplexing a number of small packets into a big one or fragmentation.This work presents a study of how to determine the technical and functional characteristics of the buffer of a certain device (e.g. size, input and output rate and others characteristics related to its behaviour), or even in a remote node. Two different methodologies are considered, and tested on two real scenarios which have been implemented; real measurements permit the estimation of the buffer size, and the input and output rates, when we have physical or remote access to the "System Under Test". In case of having physical access, the maximum number of packets in the queue can be determined by counting. In contrast, if the node is remote, its buffer size can be estimated. We have obtained accurate results in wired and wireless networks.
