    We present a decentralized design that dynamically allocates resources to multiple services inside a global server cluster. The design supports QoS objectives (maximum response time and maximum loss rate) for each service. A system administrator can modify policies that assign relative importance to services and, in this way, control the resource allocation process. Distinctive features of our design are the use of an epidemic protocol to disseminate state and control information, as well as the decentralized evaluation of utility functions to control resource partitioning among services. Simulation results show that the system operates both effectively and efficiently; it meets the QoS objectives and dynamically adapts to load changes and to failures. In case of overload, the service quality degrades gracefully, controlled by the cluster policies. View full abstract»

    We consider some implications of non-linear feedback, due to policy combinatorics, on policy-based management of networked services. We pay special attention to the case where the monitoring of certain aspects of Service Level Agreements is used to alter future policy dynamically, according to a control feedback scheme. Using two simple models, we show that nonlinear policies are generally unstable to service provision, i.e. provide no reliable service levels (QoS). Hence we conclude that automated control by policy-rule combinatorics can damage quality of service goals. View full abstract»

    While security is often supported in standard management frameworks, security is of major importance in the management plane. In this paper we address the provisioning of a security “continuum” for management frameworks based on multi-protocol gateways. We provide an in depth security extension of such a gateway using the Role Based Access Control paradigm and show how to integrate our approach within a broader XML-based management framework. Two case studies are investigated: while the first one proposes to map an XML-based RBAC policy to SNMP access control model, the second one maps the same policy to CLI security levels. The target objective is to provide consistent access control policies not only locally on each device whatever be the network management framework but also globally through the managed domain.

  • Techniques for integrating sensors into the enterprise network

    Cheap programmable sensor devices are becoming commercially available. They offer the possibility of transforming existing enterprise applications and enabling entirely new ones. The merging of sensor networks into the enterprise network poses some distinct problems. In particular, information from theses devices must be obtained in a way which minimizes their energy use and must be aggregated and filtered before being sent to the application server to prevent it from being overwhelmed. We describe a range of complementary techniques for integrating sensors into an enterprise network. These comprise new architectural entities within the enterprise network — edge server — new means of sharing information within the enterprise network — messaging binning — and new protocols for extracting information from the sensor network — Messo.
