Virtualization technology is widely used in server consolidation, high performance computing, and cloud data center due to its benefits on high resource utilization, flexible manageability, and dynamically scalability. However, it also introduces additional performance overheads. It’s worthy to evaluate the overheads and to find the bottleneck of virtualization in different scenarios. In this p...

This application to the Santa Fe Institute’s Business Network Fellowship presents a model for distributed control that applies to current and planned work in computer network manageability and security. First I review the problems facing the industry in networks of large numbers of machines. Second, I describe methods from a current project on self-propagating worm detection. Finally I embed th...

As application developers move toward building component-based web service applications, the traditional tools and development models turn out insufficient to meet the new requirements from rapid evolution due to the speed of the Internet. This paper presents an XML-powered framework designed to build adaptive software components, in order to relieve developers from low-level implementation tas...

Corpus annotation is an important aspect in speech applications where stochastic models need to be trained and evaluated. Multimodal corpora are also annotated. Moreover, corpus annotation is an essential phase in the construction of emotion recognizer engines. Large corpora, as they are essential to construct representative knowledge bases, have been a problem for corpus annotators. Time consu...

VM Migration for Autonomic Fault Tolerance provides the continuous availability for applications in the event of virtual machine failures along with the benefits of improved performance and manageability. Multipath correlation coefficient approach for VM migration has been proposed, which takes into account the overutilization of CPU without performance degradation based on work variability. Th...

Organizations today face increasing pressures to integrate their processes across disparate divisions and functional units, in order to remove inefficiencies as well as to enhance manageability. Process integration involves two major types of changes to process structure: (1) synthesizing processes from separate but interdependent subprocesses, and (2) decomposing aggregate processes into disti...

Use of virtual machines (VM), which concept was introduced by IBM, are increasingly due its benefits like better resource utilization and ease system manageability. Although, virtualization of I/O devices can introduce an overhead due to layer increment between VM and host. This penalty is specially wrong when the requested devices have high sustained thoughput and/or low latency. An excellent ...

Distributed Computing, the exploitation of idle cycles on pervasive desktop PC systems, offers the opportunity to increase the available computing power by orders of magnitude (10× to 1000×). Such large-scale resource sharing is a key part of the emerging “Grid” computing technologies being developed and pursued by a broad array of researchers, software vendors, and hardware vendors. However, f...

The goal of ontology-based management is to improve the manageability of network resources through the application of formal ontologies. Prior research work has studied their application to represent the management information definitions, the mapping and merging processes to obtain a semantic integration of those definitions, and the representation of behaviour and policy definitions. Using on...
