Abstract
In this paper, we study the Assured Service model proposed by Clark and Wroclawski [3, 4]. While existing schemes use service profiles that are defined in terms of absolute bandwidth, it is difficult, if not impossible, to design provisioning algorithms that achieve simultaneously good service quality and high resource utilization for such services with large spatial granularities. We propose an Assured Service model, called LIRA (Location Independent Resource Accounting), in which service profiles are defined in units of resource tokens, rather than absolute bandwidth. The number of resource tokens charged for each in-profile packet is a dynamic function of the path it traverses and the congestion level. Defining service profile in terms of resource tokens allows more dynamic and flexible network control algorithms that can simultaneously achieve high utilization and ensure high probability delivery of in-profile packets. We present an integrated set of algorithms that implement the m...
