El impacto del buffer en la calidad de servicio

TL;DR

This paper analyzes how buffer characteristics in access networks impact quality of service, especially during bursty traffic, affecting multimedia and other applications sharing the same link.

Contribution

It provides an analysis of buffer effects on QoS in access networks, focusing on buffer size, packet loss, and their influence on multimedia traffic during congestion.

Findings

Buffer size influences packet loss during congestion.

Bursty traffic can degrade multimedia quality.

Buffer characteristics affect overall network performance.

Abstract

The response in data flows transmission in real time is analyzed, for access network scenarios, in which said flows converge on an outgoing link, competing to achieve a certain level of quality of service. The concurrence of these types of flows can generate bursts of packets, which in certain circumstances can compromise the capacity of the buffers to absorb packets in congestion periods. In addition, an analysis of the characteristics of buffers in access devices is presented, especially their size and packet loss. In particular, it describes how these characteristics can affect the quality of multimedia applications when bursty traffic is generated, it also presents possible effects on the traffic of other applications that share a common link.
