【摘要】 柔性试验床是在面向服务提供的新型网络体系架构下构建的具备“三网融合”能力、拥有全新网络体制、以提供服务为导向的新型示范性平台。在面向服务提供的网络体系下,不再按照特定的用户业务需求构建网络,而是根据网络服务提供能力,每一种网络服务都可以支撑多种具有相似特性的用户业务,大多数新兴业务可以利用现有网络服务支撑。因此与传统的面向业务网络体系相比,改造网络的几率大幅度下降,网络支撑新兴用户业务的能力显著提高。柔性网络底层物理资源的核心是平台化支撑构件化处理的逻辑抽象模型,因此需要研究可重构柔性试验床的管控系统,以对可重构路由设备进行管理,提供多业务支撑的服务能力,实现网络的功能重构、性能的编程分配以及分层的管理配置。本文分析了新型网络体系的分层结构模型,并对柔性试验床的组网规划进行讨论。处于分层结构上层的柔性管控平台,使用业务聚类方法的研究成果,为用户提供规范化的网络构建需求标准,并根据底层物理资源和网络规模的不同,可以采用合适的构建方法为用户业务构建嵌入式业务支撑网。本文的核心工作是在分析柔性管控平台研究意义的基础上,提出了管控平台的基本设计原则,并且将管控平台划分为用户操作层、核心处理层和通讯接口层的三层结构进行独立的研发,并且基于柔性试验床的实际特点对网络构建算法进行了优化和实验分析。同时,为了支持其他研究者对柔性试验床进行开发和实验,管控平台开放了多个标准接口,为柔性试验床的进一步研究和发展打下了良好的基础。最后本文基于柔性试验床设计和部署了两个可重构实验场景,进一步验证试验床的重构特性以及管控平台的功能实现,也为各层次的研究人员在柔性试验床上进行网络实验提供参考。更多还原

【Abstract】 Flexible test bed is a new kind of demonstration platform with "tri-network integration" capacity, new network system and service provision oriented characteristic under the new network architecture. Under services provision oriented network system, building a network is no longer based on specific user business needs, but on network service provision capacity. Each network service can support a variety of user business needs with similar characteristics, and most of the emerging business can take advantage of existing network services. Therefore, comparing with the traditional business-oriented network architecture, the probability of network transformation is significantly declined and the robustness of supporting user business is significantly improved.The core of underlying physical resources of flexible network is the logic abstract model of platform-supporting and component-processing. So it is necessary to research the flexible control and manage system to manage the reconfigurable router devices, supply multi-business service provision capacity and support network function upgrade and reconstruction.This paper analyzes the hierarchical model of the new network architecture, and discusses the network planning of flexible test bed. Flexible control and manage platform which is on the high level of hierarchical model uses the research results of business clustering method to provide network construction standards to users, and takes advantages of appropriate methods to construct embedded business supporting network based on the different underlying resources and network sizes.The major work of this paper is proposing the design principles, devising the platform to three layers for independence development based on the analysis of significance. And this paper optimizes the network constructing algorithm and carries out several experiments. At the same time, our platform opens its several interface standards to support other researchers to develop and experiment, and this method has laid a good foundation for further research and development on the flexible test bed. Finally this paper designs and deploys two reconfigurable experiments to further validate the test bed’s capacity of reconstruction and the function of flexible control and manage platform. And this also provides reference for researchers at every level to carry out network experiments on test bed.更多还原
