Paper Abstract

We have designed and are implementing a research platform, NIST Switch, for experimenting with novel approaches to routing with quality of service (QoS) guarantees in an IP environment. NIST Switch is based on commodity PC hardware running freely-available operating systems. It implements quality of service through label switching over Ethernet, using proposed extensions to RSVP and differentiated services to signal QoS requests and distributed labels. In NIST Switch, the labels applied to packets have two fundamental uses in QoS traffic management: locally, labels select the characteristics of the queuing and traffic shaping measures applied to packets. In the network, labels identify the path segments over which traffic will flow. A label-switched route then consists of a 'bundle' of these sticks and brushes, chosen so as to achieve the appropriate aggregate behavior. NIST Switch routing algorithms attempt to optimize the set of path segments used, so as to maximize the number of service requests which can be met while bounding the number of labels allocated. As an experimental platform, NIST Switch is designed to be easily altered. Each of its key components are independently configurable modules which are readily replaceable.
