随着我国网络技术水平的飞速提升,网络被逐渐应用到生产生活的方方面面,人们对网络技术发展的关注度及使用需求度也逐渐提高。虽然现阶段计算机行业对网络技术应用的研究较为成熟,但针对网络管理模式升级与优化的研究却相对较少。传统的网络管理系统大多数都采用了集中式的管理模式,这种管理模式具有灵活度低、数据处理受限、占用带宽等方面的不足,而新兴的移动Agent技术恰巧弥补了传统网络管理中的问题。移动Agent具有信息移动、自主执行、并行操作等特点,能较好地满足现代网络发展的需求。为了提高网络管理的安全性和可靠性水平,全面优化现阶段网络管理中的不足之处,文章针对网络管理的定义、移动Agent的技术特点、技术难点等问题展开了讨论与探究,并对基于移动Agent的网络管理结构进行了描述,以期为移动Agent技术在网络管理领域中的应用等相关工作提供指导。 相似文献

The continuously increasing complexity of communication networks and the increasing diversity and unpredictability of traffic demand has led to a consensus view that the automation of the management process is inevitable. Currently, network and service management techniques are mostly manual, requiring human intervention, and leading to slow response times, high costs, and customer dissatisfaction. In this paper we present AutoNet, a self-organizing management system for core networks where robustness to environmental changes, namely traffic shifts, topology changes, and community of interest is viewed as critical. A framework to design robust control strategies for autonomic networks is proposed. The requirements of the network are translated to graph-theoretic metrics and the management system attempts to automatically evolve to a stable and robust control point by optimizing these metrics. The management approach is inspired by ideas from evolutionary science where a metric, network criticality, measures the survival value or robustness of a particular network configuration. In our system, network criticality is a measure of the robustness of the network to environmental changes. The control system is designed to direct the evolution of the system state in the direction of increasing robustness. As an application of our framework, we propose a traffic engineering method in which different paths are ranked based on their robustness measure, and the best path is selected to route the flow. The choice of the path is in the direction of preserving the robustness of the network to the unforeseen changes in topology and traffic demands. Furthermore, we develop a method for capacity assignment to optimize the robustness of the network. 相似文献

Network virtualization is receiving immense attention in the research community all over the world. There is no doubt that
it will play a significant role in shaping the way we do networking in the future. There have been different approaches to
virtualize different aspects of the network: some are focusing on resource virtualization like node, server and router virtualization;
while others are focusing on building a framework to set up virtual networks on the fly based on different virtual resources.
Nevertheless, one very important piece of the puzzle is still missing, that is “Wireless Virtualization”. The virtualization
of the wireless medium has not yet received the appropriate attention it is entitled to, and there have only been some early
attempts in this field. In this paper a general framework for virtualizing the wireless medium is proposed and investigated.
This framework focuses on virtualizing mobile communication systems so that multiple operators can share the same physical
resources while being able to stay isolated from each other. We mainly focus on the Long Term Evolution (LTE) but the framework
can also be generalized to fit any other wireless system. The goal of the paper is to exploit the advantages that can be obtained
from virtualizing the LTE system, more specifically virtualizing the air interface (i.e. spectrum sharing). Two different
possible gain areas are explored: spectrum multiplexing and multi-user diversity. 相似文献
