A WSDM-Based Architecture for Global Usage Characterization of Grid Computing Infrastructurese use of infrastructures comprised of heterogeneous grid middleware. Second, they do not allow the specification of policies to publicize the collected information. Third, they do not generate statistics about the applications that are executed on the grid. To fill this gap, we propose an architectu

Management of DiffServ-over-MPLS Transit Networks with BFD/OAM in ForCES Architecture maintenance) in ForCES (Forwarding and Control Element Separation) architecture for QoS-guaranteed DiffServ-over-MPLS traffic engineering. The proposed BFD and ForCES functions are implemented on Intel 2400 network processor, where BFD/OAM packets for MPLS TE-LSP are exchanged every 5 ~ 10 ms inter

Detecting Bottleneck in ,-Tier IT Applications Through Analysisducing business risks associated with violating sophisticated service-level agreement (SLA). Currently, performance verification during the staging process is accomplished through either an expensive, cumbersome manual approach or ad hoc automation. This paper describes an automation approach as par

Fast Extraction of Adaptive Change Point Based Patterns for Problem Resolution in Enterprise Systemslem occurs in such environments, it is critical that the health monitoring software identifies the root cause with . delay. A technique commonly used for isolating root causes is rule definition, which involves specifying combinations of events that cause particular problems. However, such predefine

Business-Driven Decision Support for Change Management: Planning and Scheduling of Changes as .. This paper begins to address this problem by taking business considerations into account; this is done through a business-driven IT management (BDIM) approach. A reference architecture that follows BDIM principles is sketched; it includes a mathematical model linking IT availability metrics t

Using Argumentation Logic for Firewall Policy Specification and Analysis to configure correctly. Given their widespread use, it is crucial that network administrators have tools to translate their security requirements into firewall configuration rules and ensure that these rules are consistent with each other. In this paper we propose an approach to firewall policy spe

In an avian model the primitive erythropoiesis derived from extraembryonic yolk sac is short lived and the evidence that adult hematopoiesis arises from intraembryonic sources has been extended from birds to mammals.
