Abstract

This paper presents an overview of software radio architectures for testing quality-of-service (QoS) aware IP data services over a typical third-generation radio interface. The testbed is implemented using a hard real-time micro-kernel known as RTLinux, running beneath the Linux operating system, for providing real-time end-to-end functionality. The testbed runs on a variety of Intel Pentium-based computing platforms including laptops and high-end servers. Layers 1 and 2 are compliant with the 3GPP specifications forTdd operation and layer 3 provides a direct interconnection with an IPv6 core network. The intent is to study the impact of an ip core network and QoS constraints on the physical and link layers as well as the co-design of physical layer configurations and IP layer networking.

Résumé

Cet article présente un aperçu des architectures radio logicielles destinées aux tests de la qualité de service (Quality of Service: QoS) pour des services IP de transmission de données à travers des interfaces radio 3e génération. Le banc d’essai est réalisé en utilisant un micro-noyau temps réel comme RTLinux, qui tourne sous un système d’exploitation Linux, assurant ainsi des fonctionnalités temps réel de bout en bout. Le banc d’essai consiste en une plateforme comprenant des PC portables et des serveurs à base de processeurs Intel Pentium. Les couches 1 et 2 sont totalement compatibles avec les spécifications de la norme 3GPP pour le modeTdd. Quant à la couche 3, elle est conçue pour offrir une interconnexion directe avec des réseaux IPv6. Notre objectif étant d’étudier, aussi bien, l’impact des architectures ip et des contraintes de la qualité de service sur les couches physique et de liaison, que la conception conjointe des configurations de la couche physique et de la couche IP.
