    RESUMEN: Proveer Calidad de Servicio (QoS) es un requerimiento obligatorio cuando se requiere transmitir tr谩fico de telemedicina, debido a la importancia de la informaci贸n sobre el estado de salud del paciente. La Administraci贸n Activa de Colas (AQM) se ha convertido en una estrategia ampliamente elegida para proporcionar QoS, porque no requiere interacci贸n con los equipos de comunicaci贸n de la red. Este documento propone un nuevo esquema de control de acceso basado en ocupaci贸n de colas y la definici贸n de 3 clases de tr谩fico. Esto con el objetivo de ofrecer las mejores caracter铆sticas de QoS a las altas prioridades, mediante la adaptaci贸n de la probabilidad de rechazo del tr谩fico de llegada

    VoIP network architectures and QoS strategy

    Voice over IP (VoIP) has received much attention in recent years with the promise of lower costs, as well as new revenue-generating services. Cost and services advantages of carrying voice over IP compared to over the current circuit network are made possible by a common high-capacity packet infrastructure for voice, data, and multimedia services. An important requirement of such a packet infrastructure is the ability to provide publicswitched telephone network (PSTN) grade quality without excessive overprovisioning. In this paper, we describe an approach to offer AbsoluteQoS TM to voice and other demanding applications over a general-purpose packet network. AbsoluteQoS is defined as the ability to provide an engineered bound on call-blocking and quantitative QoS guarantee that calls-in-progress will receive. The proposed strategy is based on key innovations in architectures and protocols, as well as business models of PSTN and packet networks. 漏 2003 Lucent Technologies Inc
