    The rapid deployment of interactive and multimedia applications, and the increased mobility of computers leads to the need for new technical solutions in computing systems. The Internet comprises a heterogeneous set of networks with very different characteristics, especially considering the increased usage of wireless networks. Even the end systems are architecturally very different, and these fac... View full abstract»

    Considers the problem of scheduling packets in a multiplexer, the aim being to provide sufficient service to each traffic stream such that their objectives are just satisfied, thus maximising the resources available for other streams. We propose a novel scheduling scheme based on stochastic learning automata which is capable of satisfying a variety of delay requirements in a dynamic traffic enviro... View full abstract»

    Combined input-output queueing switches (CIOQ) have better scaling properties than output queueing (OQ) switches. However, a CIOQ switch may have lower switch throughput and, more importantly, it is difficult to control delay in a CIOQ switch due to the existence of multiple queueing points. In this paper, we study the following problem: can a CIOQ switch be designed to behave identically to an OQ... View full abstract»

    A lightweight resource reservation protocol for unicast Internet traffic is described. The key feature of the protocol is that resources can be reserved on a per-connection basis without introducing connection states in the network. Issues addressed in the paper include robustness against lost signalling messages, route changes and robustness against theft-of-service attacks View full abstract»

    Network applications require certain individual performance guarantees that can be provided if enough network resources are available. Consequently, contention for the limited network resources may occur. For this reason, networks use flow control to manage network resources fairly and efficiently. This paper presents a distributed microeconomic flow control technique that models the network as co... View full abstract»

    Among packet scheduling disciplines for providing end-to-end quality-of-service (QoS) guarantees to different applications, two classes of algorithms have received particular attention: those based on generalized processor sharing (GPS) and those based on earliest-deadline first (EDF) scheduling. The powerful properties of GPS-based schemes translate easily into simple call admission control (CAC)... View full abstract»

    The vBNS (very-high-performance Backbone Network Service) is a high-speed Internet Protocol (IP) over an ATM national backbone network. A “reserved bandwidth” service is designed based on the network traffic characteristics as the initial quality-of-service (QoS) offering for the vBNS user community. This paper outlines the improved configuration in the ATM layer and the required new r... View full abstract»

    Online measurement of traffic can improve the quality of network monitoring and call admission control algorithms by providing reliable estimates of QoS parameters. We propose to estimate QoS by fitting an appropriate function to the buffer occupancy distribution of a single-server first-come/first-served queue. We collect samples of the buffer occupancy distribution just after packet arrivals in ... View full abstract»

    The current network architecture is based predominantly on stand-alone routers. It is becoming overtaxed with the introduction of integrated services. In this paper, we propose the SAAM (Server and Agent-based Active network Management) architecture that scales well with integrated services. SAAM relieves individual routers from most routing and network management tasks. Instead, it employs a smal... View full abstract»

    Presents an agent-based architecture for resource reservations. For each domain in the network, there is an agent that is responsible for admission control. The architecture provides scalable per-link resource reservations in agents and low per-packet overhead in routers. The key ideas are the following.

    In an integrated-services packet-switching network (e.g. the Internet of the future, which is expected to offer real-time as well as non-real-time services), the charging policy must be service-dependent, but how should charges vary with the type of service and with the quality of service (i.e. with the QoS parameters and with their respective values)? We start from a list of the properties the po... View full abstract»

    Shows that the selection of a quality of service (QoS) becomes a difficult task for the user when he is faced with different prices for different QoSs. Even if the user is only facing a best-effort service, he might be unable to determine the minimal-cost selection of bandwidth. This article shows that the user needs support to get the best service regarding his personal situation. The mechanisms ... View full abstract»

    Addresses the admission control problem for leaky bucket controlled sources when assuming fluid flows and employing bufferless multiplexing. We have derived new conservative upper bounds enabling us to use the simple admission criteria associated with a Gaussian distribution for the bit rate offered to a link.

    In a distributed environment where multiple applications compete and share a limited amount of system resources, applications tend to suffer from variations in resource availability and are desired to adapt their behavior to the resource variations of the system. We propose a task control model to rigorously model the dynamics of an adaptive system using digital control theory. With our task contr... View full abstract»

    In bandwidth-limited access networks, dynamic resource allocation can increase the link utilization and decrease the required network buffering. In this paper, we propose a new policy in which the visual content of video is used to determine the bandwidth needed for its transmission. The policy is based on a novel framework of content-based video traffic modeling. Based on simulation results, the ... View full abstract»
