“…The performance guarantees field depicts the guarantees that the network offers to the customer for the packet stream described by the flow descriptor over the topological extent given by the scope value. A set of performance parameters for service-compliant traffic (in accordance with the IETF IP Performance Metrics Working Group, Roth, 2003) that applies to the case of the EF-based service but also to other DiffServ-based services is the following:…”

“…New applications, such as IP telephony, require Contract/grant sponsor: GEANT and SEQUIN; Contract/grant sponsor: GRNET mechanisms. SEQUIN [3], a European Commission Information Society Technologies (IST) research project, in cooperation with DANTE, the coordinator of GEANT, specified the 'Premium IP' service implementation model based on the DiffServ Expedited Forwarding PHB (EF-PHB) [4]. Premium IP offers explicit QoS guarantees, such as bounded delay and delay variation, and negligible packet loss to conforming traffic.…”

SUMMARYThe differentiated services (DiffServ) framework is widely proposed as an efficient method for providing advanced IP services to large-scale networks, with QoS requirements. However, the provisioning of such services in production networks has proved to be more difficult than initially expected, in defining, setting and verifying appropriate Service Level Agreements (SLAs). GEANT, the Gigabit core pan-European research network, on a pilot basis introduced 'Premium IP' service, offering bounded delay and negligible packet loss to the European National Research & Education Networks (NRENs) that it interconnects. However, large scale provisioning of this new service requires the definition of efficient interaction procedures between administrative domains involved and methods for SLA monitoring. This paper focuses on these issues and presents the experience acquired from the early experiments in GEANT, as an example of hierarchical Gigabit multi-domain environment, enabled with QoS provisioning to its constituent NRENs. This model scales more efficiently than the common peering Internet Service provider (ISP) commercial paradigm. Finally, we outline other options that promise QoS, such as Layer 2 VPNs in MPLS backbones, with non-standard (yet) mechanisms.

“…Therefore, concepts are being developed to address the challenge of provisioning QoS assurances at various levelsmanagement of packets, configuration of inter-networks, and service delively modes to customers (Giordano et al 2003;Cortese et al 2003;Engle et al 2003;Mykoniati et al 2003). Pilot studies are in progress that test these concepts (Roth et al 2003). There has also been substantial empirical work in internet traffic monitoring and characterization and network performance analysis (Paxon 1999;Yajnik et al 1999; SLAC; CAIDA; NLANR).…”

The technological advances in recent years are allowing Internet Service Providers (ISPs) to provide Quality of Service (QoS) assurance for traffic through their domains. This article develops a spot pricing framework for intra-domain expected bandwidth contract with'a loss based QoS guarantee. The framework accounts for both the cost and the risks associated with QoS delivery. A nonlinear pricing scheme is used in pricing for cost recovery; a utility based options pricing approach is developed for risk related pricing. The application of options pricing in intemet services provides a mechanism for fair risk sharing between the provider and the customer, and may be extended to price other uncertainties in QoS guarantees.
