【摘要】：本文研究的内容是973项目《信息服务的模型与机理研究》的“面向公共信息服务的网络协同与主动服务”专题。我们从网络特性入手,在充分总结和分析各类融合网络的特点及其工作机理的基础上,针对互联网交互性强和广播网高带宽、覆盖面广的优点,提出将二者进行融合,弥补互联网访问所呈现的幂律分布特性和广播网的单向性所带来的劣势,互补工作。提出自适应互补机制,并给出融合网络下组播过程中轮播次数期望的解析解,从多方面感知外在环境变化的特征,使用户能够得到良好的信息服务。为证明以上原理和机制的可行性,设计并实现了一套基于融合网络播存机制的数据发布系统,实现了单向信道中大文件的发布、内容播出控制和自适应互补机制等关键技术。最后对原型系统进行了理论分析和验证,结果表明,该系统在大规模数据发布方面可靠性较强,传输效率较高。本文对融合网络的工作机制和相关技术进行分析和归纳,为今后研究数据在融合网络下的传输规律和性能提供了理论依据；提出网络融合情况下的数据发布机制、自适应互补机制等,能够高效地进行大规模数据分发；并在此基础上实现基于融合网络播存机制的数据交换系统,可以提高公共信息服务的服务质量。此外,可将本文研究的基于融合网络播存机制的数据发布架构,在内容定位方面进行扩展,形成同时具有内容标签和IP地址双重定位机制的传输模式,从而更好地提供公共信息服务。
[Abstract]:The research content of this paper is "Network collaboration and active Service for Public Information Service" of 973 Project "Model and Mechanism Research of Information Service". On the basis of summarizing and analyzing the characteristics and working mechanism of all kinds of convergent networks, we put forward to combine them in view of the strong interactivity of the Internet and the advantages of high bandwidth and wide coverage of broadcasting networks. It makes up for the disadvantage of power law distribution of Internet access and the unidirectionality of broadcasting network. An adaptive complementary mechanism is proposed, and an analytical solution to the expectation of the number of rotations in the multicast process under the fusion network is presented, which can perceive the characteristics of the external environment from many aspects, so that the users can get good information services. In order to prove the feasibility of the above principles and mechanisms, a data publishing system based on integrated network broadcast storage mechanism is designed and implemented. The key technologies such as the release of large files in one-way channels, content broadcast control and adaptive complementary mechanism are realized. Finally, the prototype system is theoretically analyzed and verified. The results show that the system is reliable and efficient in large-scale data release. In this paper, the working mechanism and related technologies of the fusion network are analyzed and summarized, which provides a theoretical basis for the future research on the transmission rules and performance of the data in the fusion network, and puts forward the data release mechanism under the condition of network convergence. The adaptive complementary mechanism can efficiently distribute large-scale data, and on this basis, a data exchange system based on integrated network broadcast and storage mechanism can be implemented, which can improve the quality of service of public information services. In addition, the data publishing architecture based on the integrated network broadcast and storage mechanism studied in this paper can be extended in content location to form a transmission mode with dual location mechanism of content label and IP address at the same time. In order to better provide public information services.
