چکیده

Computing grids require the underlying network infrastructure to be properly configured for provisioning of appropriate communications among their nodes. The management of networks and grids are currently executed by different tools, operated by different administrative personnel. Eventually, the grid communication requirements need corresponding support from the network management tools, but such requirements are fulfilled only when grid administrators manually asks the network administrators for the corresponding configurations. In this paper, we propose a policy translation mechanism that creates network policies given grid requirements expressed in grid policies. We also present a system prototype that allows (a) grid administrators to define grid policies, and (b) network administrators to define translating rules. These translating rules are used by the translation mechanism proposed by this work for the generation of the necessary underlying network configuration policies. Resumo. Grids computacionais requerem que a infra-estrutura de rede subjacente seja adequadamente configurada para o fornecimento apropriado dos serviços de comunicação entre os nodos do grid. O gerenciamento da rede e do grid atualmente são executados através de diferentes ferramentas, operadas por diferente pessoal administrativo. Eventualmente, os requisitos de comunicação do grid precisam de um suporte de comunicação correspondente das ferramentas de gerenciamento de redes, mas esses requisitos somente são atendidos quando os administradores do grid manualmente requisitam aos administradores da rede as configurações correspondentes. Este artigo propõe um mecanismo de tradução de polı́ticas que cria polı́ticas de rede a partir dos requisitos do grid expressos nas polı́ticas de grid. É apresentado também um protótipo que permite (a) administradores de grid definirem polı́ticas de grid e (b) administradores da rede definirem regras de tradução. Essas regras de tradução são usadas pelo mecanismo de tradução proposto neste trabalho para geração das polı́ticas necessárias para configuração da rede subjacente.

A New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions

Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...

Context Aware Adaptive Service based Dynamic Channel Allocation Approach for Providing an Optimal QoS over MANET

Large variations in network Quality of Service (QoS) in terms of bandwidth, latency and jitter may occur during media transfer over mobile ad-hoc networks. Applications need to adapt their functionality according to dynamic change of their QoS update. This paper proposes an enhanced service based platform to provide adaptive network management services to higher level application layer componen...

A JOINT DUTY CYCLE SCHEDULING AND ENERGY AWARE ROUTING APPROACH BASED ON EVOLUTIONARY GAME FOR WIRELESS SENSOR NETWORKS

Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...
