  • Practical and analytical approaches for designing scalable on-Demand Policy-based resource allocation in stateless IP networks
    International Journal of Network Management, 2012
    Co-Authors: Kamel Haddadou, Samir Ghamri Doudane, Yacine Ghamri-doudane, Nazim Agoulmine
    Abstract:

    Today the Policy-based management (PBM) approach is recognized as an efficient solution to simplify the complex task of managing and controlling networks. To this end, the Internet Engineering Task Force (IETF) has introduced a reference framework to build PBM systems. However, this framework only addresses the provisioning of relatively long validity period services based on predefined service-level agreements. Furthermore, very little work addresses the scalability properties of the instantiation of this framework in a real network. This work aims to extend the IETF PBM framework in order to support dynamic provisioning of short-term services (end-system signalling) as well as an instantiation scheme that is scalable (distributed provisioning of edge routers). This instantiation scheme is based on the distribution of the provisioning process while keeping centralized only the parts that involve critical resources, namely bandwidth brokerage. The performance properties of the proposed scheme are then demonstrated throughout both extensive experimentation and an analytical study. The extension of this performance analysis to the case where multiple bandwidth brokers are used is also discussed. The results of this work are intended to be used as a guideline to help network operators to design a scalable PBM system in order to offer to their customers services with quality of service assurance on an on-Demand basis.

  • MMNS - A Dimensioning and Deployment Tool for on Demand Policy-Based Resource Management System
    Management of Converged Multimedia Networks and Services, 2008
    Co-Authors: Kamel Haddadou, Samir Ghamri Doudane, Yacine Ghamri-doudane, Nazim Agoulmine
    Abstract:

    Today the Policy-Based Management (PBM) approach is recognized as an efficient solution to simplify the complex task of managing and controlling networks. To this end, the IETF has introduced a reference framework to build PBM systems. However, this framework only addresses the provisioning of relatively long validity period services based on pre-defined SLAs (Service Level Agreements). Furthermore, very little work addresses the scalability properties of the instantiation of this framework in a real network. In our previous work, we presented an extension of the IETF PBM framework in order to support dynamic provisioning of short term services (end-system signaling) as well as an instantiation scheme that is scalable (distributed provisioning of edge routers). This instantiation scheme is based on the distribution of the provisioning process while keeping centralized only the parts that involve critical resources, namely the Bandwidth Brokerage. In this paper, we propose an extensive analytical study of this extended architecture. The results of this work are intended to be used as a guideline to help network operators to design a scalable PBM system in order to offer to their customers' services with QoS assurance in an on-Demand basis.

  • Proactive Two-Tier Bandwidth Brokerage for on-Demand Policy-based Resource Allocation in Stateless IP Networks
    2005
    Co-Authors: Kamel Haddadou, Samir Ghamri Doudane, Yacine Ghamri-doudane, Nazim Agoulmine
    Abstract:

    In order to improve the scalability of the IETF’s PBM architecture, we previously proposed an extension to this architecture. The aim of our proposal was to facilitate the support of on-Demand resource allocation in stateless IP networks. The proposed schema distribute part of the decision making process but keeps centralized the bandwidth brokerage operation as this latter uses a critical resources (traffic matrix). Our current work aims to render the PBM architecture completely distributed by designing a scalable scheme for bandwidth brokerage. To that end, we propose using a proactive two-tier scheme in order to improve the scalability of the resource management procedures. In this paper, we present the proposed scheme, its design features and the set of experimentations we realized in order to demonstrate its performances.

  • configuration scheduling using temporal locality and kernel correlation
    International Parallel and Distributed Processing Symposium, 2008
    Co-Authors: S Kandasamy, A Morton, Wayne M Loucks
    Abstract:

    This paper examines runtime decisions to configure hardware accelerators or execute in software. Traditionally, reconfigurable FPGAs are reconfigured on-Demand with the hardware accelerator, as it is needed by the application. If the software kernel which the hardware kernel replaces is available too, then more sophisticated decision making on reconfigurations may lead to improved execution time and reduced power consumption. The temporal locality algorithm is proposed for applications where individual kernels dominate during differing execution modes. The kernel correlation algorithm is proposed for applications where sequences of kernels are invoked in regular patterns. SystemC simulation is used to compare these two scheduling algorithms against the on-Demand Policy. Both timing and power consumption results are presented. They indicate that a fairly large reconfiguration time is required for configuration scheduling to be beneficial.
