Middleware de comunicação entre objetos distribuídos para gerenciamento de computadores baseado em redes sem fio (WSE-OS)
Universidade Estadual Paulista (UNESP), 2011Co-Authors: Crepaldi, Luis GustavoAbstract:Para simplificar o gerenciamento de computadores, vários sistemas de administração estruturados por conexões físicas adotam técnicas avançadas para gestão de configuração de software. No entanto, a forte ligação entre hardware e o software faz com que haja uma individualização desta gerência, além da penalização da mobilidade e ubiqüidade do poder computacional. Neste cenário, cada computador torna-se uma entidade individual a ser gerenciada, exigindo operações manuais de configuração da imagem de sistema. Tecnologias que oferecem gestão centralizada baseadas em conexões físicas cliente-servidor, combinando técnicas de virtualização com a utilização de sistemas de arquivos distribuídos, refletem a degradação em flexibilidade e facilidade de instalação deste sistema gerenciador. Outras arquiteturas para gerenciamento centralizado que estruturam o compartilhamento de dados através de conexões físicas e dependem do protocolo PXE, apresentam os mesmos impasses descritos anteriormente. Diante das limitações dos modelos de gerenciamento centralizado baseado em conexões físicas, o objetivo deste trabalho é o desenvolvimento de um middleware de comunicação cliente-servidor como parte integrante e necessária para um ambiente de gerenciamento centralizado em redes de comunicações sem fio. Este ambiente, denominado WSE-OS (Wireless Sharing Enviroment ? Operating Systems), é um modelo baseado Virtual Desktop Infrastructure (VDI) que associa técnicas de virtualização e sistema de acesso remoto seguro para criação de uma arquitetura distribuída como base de um sistema de gestão. WSE-OS é capaz de realizar a replicação de sistemas operacionais em um ambiente de comunicação sem fio além de oferecer abstração de hardware aos clientes. O WSE-OS pode substituir o boot local com disco rígido por um boot de uma Imagem de Sistema Única...To simplify computer Management, various administration systems structured with physical connections adopt advanced techniques to manage software configuration. Nevertheless, the strong link between hardware and software makes for an individualism of that Management, besides penalizing computational mobility and ubiquity. In this scenario, each computer becomes an individual entity to be managed, requiring manual operations of the system image configuration. Technologies that offer Centralized Management based on client-server physical connections, combining virtualization techniques with the use of distributed file systems in clusters with distributed processing on network computers reflect the deterioration in flexibility and ease of installation and maintenance of distributed applications. Other architectures for Centralized Management that structure the sharing of data through physical connections and depend on the PXE protocol, present the same dilemmas described above. Given the limitations models of Centralized Management based on physical connections, the objective of this project is the development of a middleware for client-server communication as part necessary of an environment for Centralized Management in wireless communications networks. This environment, called WSE-OS (Wireless Sharing Environment ? Operating Systems), is a model based Virtual Desktop Infrastructure (VDI), which combines virtualization techniques and secure access system for creating a distributed architecture as the basis for a Management system. WSE-OS is capable of replicating operating systems in a wireless environment, addition to providing hardware abstraction to clients. The WSE-OS can replace the boot with local hard disk to a boot from SSI (Single System Image) virtualized in server via communication middleware, increasing flexibility and allowing multiple operating systems...

p2pie a new enterprise application integration solution 60 70
Conference on Advanced Information Systems Engineering, 2015Co-Authors: Jorgen Hanson, Jens Ohlsson, Nevzat Ertan, Paul Johannesson, Stefan Wernmo, Ole Schjodtosmo, Shengnan Han, Tomas HedlundAbstract:In order to provide unified and consistent data and functionality, enterprises need to make all their applications work in an integrated manner. However, integration has become more difficult to handle when enterprises extend their business globally, more applications are implemented for supporting business activities, and more computing paradigms are adopted, e.g., cloud, social, and mobile, just to name a few. The state-of-the-art integration solutions have limitations to address the difficulty. In this paper, point to point integration engine-P2PIE, a new integration solution is presented and discussed. The solution combines distributed execution of integration with Centralized Management console, which innovate the fundamental integration infrastructures of point to point paradigm, and message systems. P2PIE is developed and tested by Sandvik over the decade. The solution has addressed Sandvik’s challenges in enterprise application integration. Agility, cost reduction and reliability of this solution are proved.

design and implementation of two level metadata server in small scale cluster file system
Journal of Chinese Computer Systems, 2007Co-Authors: Song WeiweiAbstract:The metadata server is the heart of the regular operation system in cluster file system. So the reliability and performance is one of the important problems when being designed. Presented our design of a two-level metadata server system, which behaves high reliability and performance. The merits both Centralized Management and distributed Management are considered simultaneously in our design. In this system, the advanced-metadata server is responsible for maintaining a global file directory and the whole file namespace. The double-metadata server is responsible for file metadata allocation. And this paper uses the Markov return model to analyze the reliability of the two-level metadata server. The experiment data indicates that the design can provide high throughput.
