System resource management for network servers

The Internet Engineering Task Force (IETF) is currently in the process of overhauling the architecture of the Internet to meet new challenges and support new applications. One of the most important components of that venture is the enhancement of the Internet service model from a class-less best-effort service architecture to an integrated services architecture supporting a multitude of classes and types of services. In this paper we present an overview of the different services being defined and their intended target applications. We also explore some of the challenges in designing network servers for this environment and present an architecture for system resource management that enables applications to exploit the new services offered by the emerging Internet
