Design And Implementation Of The Connectivity Protocol Based On Domestic Software And Hardware Platform For The New Internet

With the development of Internet,the number of users and scale of application are expanding every day.Due to the defects of the original design,the current network has exposed many difficult problems,such as poor security,insufficient mobility support,serious scalability and poor quality of service.The new network whitch adopts the idea of the separation of identity and position solved the above problems in a certain extent.This idea comes from the project of Universal Trustworthy Network and Pervasive Service.As the basic protocol in the new network,the Internet Connectivity Protocol is running on network devices,such as user terminals,switches,and routers of new network,to detect the connectivity of the host and network equipment,and to report the errors found in the data transmission process.At the same time,studying the new network based on the domestic hardware platform and the domestic software platform is the only way to ensure network security and build a strong network power.Based on the existing network standards and considering the characteristics of the new network architecture,we design the Internet Connectivity Protocol from three aspects:the error message,the control message and the status message,including data packet format designing,data message interaction processing.According to the analysis of the security problem of the protocol,we designed a corresponding security protection mechanism to verify the source of the data packet.Next,we implemented coding on the domestic Loongson 3B1500 CPU and the domestic kylin operation system platform,including adding basic protocol stack in the kernel code,implementing the new network unicast identity communication protocol,realizing the connectivity protocol and its security protection mechanism.Then,for the test of the protocol,we developed test tools,set up the test environment,and designed the test cases to test the consistency and security of the protocol.Finally,we analyze and summarize the work of this paper,and provide some other solutions for some problems in the paper,and give some suggestions for future work and research.
