In this regard, it is appropriate to make use of existing network structures in different hospitals and allow Telemedicine and Telehealth applications to function satisfactorily in these environments. However, the structures of existing networks are mostly Ethernet networks that serve well typical applications, but do not meet the requirements for some applications in healthcare, especially those applications that require real-time video broadcast. Therefore, this paper an approach based on QoS (Quality of Service) policies and analyzes the behavior of the metropolitan network of telemedicine in university hospitals of Natal in cases of peak usage. The purpose of these policies is to ensure the necessary conditions, such as improvements on the characteristics of predictability of the network and decrease in the jitter (the variation of delay of messages), so that telemedicine applications can be used in these computer networks in a satisfactory wayAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Rede MetropolitanaTelemedicinaQualidade de Serviçoarticle10.15628/holos.2014.987
