[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.
