Abstract
Improving quality of service (QoS) has always been a challenging task. On one hand a user or an application makes subjective QoS requests; on the other hand, a number of host machines are ready to provide resources to satisfy these requests. The architecture we propose in the paper helps build an efficient link between a user and the resource providers. This architecture implements the mobile agent technology and the concept behind the logical disk interface introduced by M. Wiebren de Jonge et al. (1993) by clearly separating QoS negotiation and resource management. Here, the mobile agent system takes care of the QoS negotiation process and the virtual host manages-allocates, reserves and deallocates-needed resources. Mobile agents help reduce network traffic through remote programming and virtual hosts handle environmental changes transparently.
