【摘要】：随着互联网的迅速普及和爆炸性发展,其体系架构原始设计方案中的缺陷和弊端逐渐显露出来：现有互联网难以根据实时网络状态动态适配网络资源,导致网络传输效率低下、网络服务方式相对僵化；难以高效使用网络资源并提供便捷的网络服务,能耗问题突出。为了有效地解决这些问题,最终实现网络资源的动态适配,网络信息的收集和网络性能的监测显得尤为重要。本文的工作依托国家973项目“智慧协同网络理论基础研究”,研究并实现网络信息的采集和网络状态的监测。本文采用OSPF协议进行信息的收集和传递,实现对网络节点和链路状态的动态感知,研究重点在于信息获取与传递机制。网络状态信息的收集是动态适配网络资源的实现基础,利于智慧协同网络的进一步研究,具有重要的意义。本文首先简要分析了现有互联网架构存在的种种弊端和缺陷,提出了重新进行网络架构设计的必要性,阐述了“智慧协同网络”体系架构对现有网络问题带来的改善和彻底解决。其次,分析各种网络信息收集方案的利弊,并选择OSPF协议作为信息收集机制。随后,对基于OSPF协议的网络信息收集方案进行阐述,将系统设计成三个模块分别完成信息的基础收集、传递和存储展示,并针对网络信息传递模块进行更详细的设计。最后,搭建测试环境对该方案进行功能测试。本文所述网络信息收集方案成功的实现了网络信息的收集与传递,为智慧协同网络架构下动态适配网络资源的进一步实现奠定了基础。
[Abstract]:With the rapid popularization and explosive development of the Internet, the defects and disadvantages in the original design scheme of its architecture are gradually revealed: it is difficult for the existing Internet to dynamically adapt network resources according to the real-time network state, resulting in low network transmission efficiency and relatively rigid network service mode; it is difficult to use network resources efficiently and provide convenient network services, and the problem of energy consumption is prominent. In order to solve these problems effectively and finally realize the dynamic adaptation of network resources, the collection of network information and the monitoring of network performance are particularly important. The work of this paper relies on the national 973 project "basic Research of Intelligent Cooperative Network Theory", and studies and realizes the collection of network information and the monitoring of network status. In this paper, OSPF protocol is used to collect and transmit information to realize the dynamic perception of network nodes and link states, and the research focuses on the mechanism of information acquisition and transmission. The collection of network state information is the basis of dynamic adaptation of network resources, which is beneficial to the further research of intelligent collaborative network and is of great significance. This paper first briefly analyzes the disadvantages and defects of the existing Internet architecture, puts forward the necessity of redesigning the network architecture, and expounds the improvement and thorough solution of the existing network problems brought by the "intelligent collaborative network" architecture. Secondly, the advantages and disadvantages of various network information collection schemes are analyzed, and OSPF protocol is selected as the information collection mechanism. Then, the network information collection scheme based on OSPF protocol is described, and the system is designed into three modules to complete the basic information collection, transmission and storage display, and the network information transmission module is designed in more detail. Finally, the test environment is built to test the function of the scheme. The network information collection scheme described in this paper successfully realizes the collection and transmission of network information, which lays a foundation for the further realization of dynamic adaptation of network resources under the framework of intelligent collaborative network.
