Research On Invulnerability Of Mapping Server In Smart Collaborative Identifier Network

With the rapid increase of users and applications in the internet,many of the defects(such as security,mobility,survivability,etc.)in the original design idea are gradually emerging.As one of the future network architecture research programs,the smart collaborative identifier network proposed by the national engineering laboratory of the next generation of Internet equipment of Beijing Jiaotong University,it aims to fundamentally solve the problems of "control and data","resources and location","users and networks" triple binding problem.Triple binding is the root cause of traditional Internet static,rigid,so the application of smart collaborative identifier network in various fields has been widely recognized.As the key indicator of the future network architecture,invulnerability characterizes the ability to maintain a certain level of performance after a network failure.Based on the theory of smart collaborative identifier network,this paper focuses on the problem of invulnerability from the network topology and mapping server and puts forward the relevant optimization strategy.The main contents of the thesis include:Firstly,a link weight optimization scheme is proposed.Based on the mathematical relationship between the first order difference and the invulnerability of the centroid degree,the usage rate of the network node is adjusted by changing the packet transmission path.A key node protection scheme is proposed.According to the maximum node degree to determine the key node set,through a reasonable increase in link redundancy,reducing the critical node attack probability.Secondly,the design and implementation of smart collaborative identifier network mapping server invulnerability optimization program.The thread pool module is designed to improve the mapping mode from single thread processing mapping mode to multi-thread processing and improve the processing ability of mapping server when receiving high concurrent request.The design of the hash module,the realization of the dynamic hash table,so that the mapping server memory hash table to meet the query mapping relationship between the time complexity of O(1),but also to ensure that the hash table will not take up too much memory,To improve the utilization of storage resources.Then,set up a test environment,and the above programs and modules were verified.The test results show that the above scheme and module can effectively improve the invulnerability of the smart collaborative identifier network mapping server.Finally,the paper is summarized and the future work is forecasted.
