    This paper presents a decentralized auction-based approach to pricing of edge-allocated bandwidth in a differentiated services model for the Internet. The players in this architecture are users, one raw-capacity seller per network and one broker per service per network. With the progressive second price auction mechanism as the basic building block, we conduct a game theoretic analysis, deriving o... View full abstract»

    When reservation-based service differentiation is offered in an IP network, it is crucial for a network provider to appropriately charge for service invocations. 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 mult... View full abstract»

    We present an approach to managing and pricing service level agreements (SLA) for differentiated services that uses a simple upper bound for the effective bandwidth of the conforming traffic as a proxy for resource usage. The bound depends on the user's traffic profile (peak rate and token bucket descriptor). Usage charges for a specific time period are proportional to this proxy, and their calcul...

    The creation, deployment and management of network architecture is manual, time consuming and costly. To the network architect the creation process is ad-hoc in nature, based on hand crafting small-scale network prototypes that evolve toward wide scale deployment. We envision a different paradigm where `spawning networks' are capable of profiling, spawning, architecting and managing distinct virtu... View full abstract»

    We have designed an agent-based architecture for quantitative service provisioning in differentiated services capable networks. For each link-state routing domain in the network there is a topology-aware QoS agent (also known as a bandwidth broker) responsible for admission control. The architecture provides resource reservations for aggregated virtual leased lines between network domains. In this... View full abstract»

    In this paper, we study one type of DoQoNS (denial of quality of network service) attacks: attacks directly on the resource reservation and setup protocol. Particularly, we have studied and analyzed the RSVP protocol. Two contributions are: first, we performed a security analysis on RSVP which demonstrates the key vulnerabilities of its distributed resource reservation and setup process. Second, w...

    In the Coqos project task performance measures and a corresponding framework are suggested and pursued as a novel and more suitable means for determining utility curves. TPM are intended to avoid limits inherent in traditional measures like mean opinion scores. MOS rely merely on subjective ratings rather than on more objective performance in relation to a particular task or application of interes... View full abstract»

    We present a software framework that facilitates the development of adaptive applications. This framework allows the installation of application-dependent policies which govern the adaptive behaviour of the application. These policies take into account user preferences and resource availability. The framework provides a generic interface to a variety of re-usable resource classes. We describe an a...

    It is common belief that the integrated services architecture (IntServ) is not scalable to large networks as, e.g., the global Internet. 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 aggregat... View full abstract»

    We prove analytically that, as claimed in Jacobson and Floyd's (1993) initial paper on RED, RED gateways “avoid the bias against bursty traffic”, meaning that bursty traffic suffers more losses than smooth traffic with tail drop (TD) gateways, but both types of traffic suffer equally with RED gateways. We also show, again as claimed by Jacobson and Floyd, that RED gateways mark or drop... View full abstract»

    IP is often referred to as the waist of the hourglass, because of the simple model the Internet provides packet level communication compared to other approaches (e.g., FR, X.25 or B-ISDN), but runs over a complex plethora of links and switched networks, and is used by a firmament of application and transport protocols. The ever increasing demand for capacity is pushing us past the 40 Gbit/s barrie... View full abstract»

    We apply and evaluate a new efficient algorithm for finding maximally link disjoint pairs of paths in a network. We apply this algorithm for QoS routing in connection-oriented networks that support calls with multiple QoS requirements. Our algorithm (called MADSWIP) is applied for precomputing paths in advance of call arrivals. Through simulations, we compare our QoS routing method to another meth... View full abstract»

    We investigate the problem of topology aggregation (TA) for scalable, QoS-based routing in ATM networks. TA is the process of summarizing the topological information of a subset of network elements. This summary is flooded throughout the network, and is used by various nodes to determine appropriate routes for connection requests. A key issue in the design of a TA scheme is the appropriate balance... View full abstract»

    Many packet schedulers for QoS networks are equipped with a rate control mechanism. The function of a rate control mechanism (rate controller) is to buffer packets from flows which exceed their negotiated traffic profile. It has been established that rate controllers lead to reduced buffer requirements at packet switches, and do not increase the worst-case delays in a deterministic service. On the...

    There is much attention given today to the provisioning of service quality in the Internet. In this position paper we advocate the use of an architecture that improves the integrated-services architecture and allows it to be brought into a differentiated-services context. The main idea in our work is to move functionality and per-session state from the network nodes out to the hosts. Such decentra... View full abstract»

    Mechanisms for service differentiation in datagram networks, such as the Internet, rely on packet classification in routers to provide appropriate service. Classification involves matching multiple packet header fields against a possibly large set of filters identifying the different service classes. In this paper, we describe a packet classifier based on tries and binomial trees and we investigat... View full abstract»

    We propose asymmetric best-effort, a novel service to provide a “throughput versus delay jitter” differentiated service for IP packets. With this service, every best effort packet is marked as either green or blue. Green packets, typically sent by real-time applications such as interactive audio, receive more losses during bouts of congestion than blue ones. In return, they receive les... View full abstract»
