For internal calculation as well as external price representation, a notion of costs and prices for communication services is needed. In this paper, general requirements for cost and price calculation are analysed for packet-switched multi-service networks. We conclude that internal price calculation should be linear, based on resource usage and uniform across multiple service classes. Accordingly, we specify refinements for service class definitions and present a price calculation method for the IETF's integrated services architecture. The application of such a price representation to existing pricing and charging approaches is shown. Finally, certain economic aspects of the guaranteed service class are analysed and the results are expressed using linear price representation.","PeriodicalId":435117,"journal":{"name":"1999 Seventh International Workshop on Quality of Service.

In other words MPLS integrates the label-swapping paradigm with network-layer routing. Differentiated Services define a model for implementing scalable differentiation of QoS in the Internet. Packets are classified and marked, policed and shaped at the edge of the network in order to receive a particular per-hop forwarding behaviour on nodes along their path. The per-flow state does not need to be maintained in the interior network nodes, thus leading to increased scalability. This obviates the use of complex signalling protocols like RSVP. The inherent characteristics of MPLS make it a very good candidate for providing differentiated services. In this paper we describe various approaches which can be used to support differentiated services in MPLS environments.","PeriodicalId":435117,"journal":{"name":"1999 Seventh International Workshop on Quality of Service.

This is due to the ambitious goal of providing per-flow QoS and the resulting complexity of fine-grained traffic management. One solution to this problem is the aggregation of IntServ traffic flows in the core of the network. While one might suspect that aggregation leads to allocating more resources for the aggregated flow than for the sum of the separated flows if flow isolation is to be guaranteed, we show in this paper that for IntServ's guaranteed service flows this is not necessarily the case even if flow isolation is retained. We compare different approaches to describing the aggregated traffic and analyze their impact on bandwidth consumption and ease of flow management. Applications of these theoretical insights could be to use the derived formulas for resource allocation in either a hierarchical RSVP/IntServ, IntServ over DiffServ (differentiated services), or IntServ over ATM network.","PeriodicalId":435117,"journal":{"name":"1999 Seventh International Workshop on Quality of Service.
