A Weakly Coupled Adaptive Gossip Protocol for Application Level Active Networks
With the sharp increase in heterogeneity and distribution of elements in wide-area networks, more flexible, efficient and autonomous approaches for management and information distribution are needed. This paper proposes a novel approach, based on gossip protocols and firefly synchronisation theory, for the management policy distribution and synchronisation… (More)
Policy-Based Resource Management for Application Level Active Networks
The emerging active network concepts, particularly those focusing on the application level, will provide the users with the flexibility of deployment of customised services on the operator's infrastructure. This will be achieved through deployment of user customised control code in virtual execution environments residing on the network nodes such as routers… (More)
Active Robust Resource Management in Cluster Computing Using Policies
We present an implementation of a policy-based management architecture for emerging communications and computing paradigms such as Active Networks and the Grid. To manage such open, highly distributed and decentralized environments, an approach based on policy concepts is adopted, allowing support for active, dynamic adaptability in network elements,… (More)
Policy-based Management for ALAN-Enabled Networks
This paper presents the architecture, the policy schema, and the policy specifications necessary to accomplish effective management of the Application Level Active Networking (ALAN) environment. Using ALAN, developers can engineer applications through the network by utilising platforms (active servers) on which 3 rd party software (proxylets) can be… (More)
Development of Grid e-Infrastructure in South-Eastern Europe
Over the period of six years and three phases, the SEE-GRID programme has established a strong regional human network in the area of distributed scientific computing and has set up a powerful regional Grid infrastructure. It attracted a number of user communities and applications from diverse fields from countries throughout the South-Eastern Europe. From… (More)
Integrity and Security of the Application Level Active Networks
The advances in programmable networks enforce the importance of ensuring and maintaining the integrity and security of the network and the supporting systems. In the future programmable network scenarios, the threats to integrity and security will rapidly increase as third-party value added service providers and end-users start deploying their customised… (More)
Security and Resource Policy-based Management Architecture for
Application Layer Active Networks (ALAN) allow quick and efficient deployment, on the active servers, of user-customised services (proxylets). Programmability above the transport layer makes this approach distinct form other active network initiatives. This scenario raises the issues of efficient resource management on the active server. Moreover, the… (More)
Improving Similarity Search in Time Series Using Wavelets
AbstrAct Sequences constitute a large portion of data stored in databases. Data mining applications require the ability to process similarity queries over a large amount of time series data. The query processing performance is an important factor that needs to be taken into consideration. This article proposes a similarity retrieval algorithm for time… (More)
The DORII project test bed: Distributed eScience applications at work
Much interest has arisen recently on the access to and management of remote instrumentation and laboratory equipment in general. The complexity of activities related to these topics can be summarized under the name of Remote Instrumentation Services, where the term “instrumentation” includes any kind of experimental equipment, and the term… (More)
