| Smart integration identity networking is a solution,which is in response to the highspeed mobile wireless network transmission performance in the scene of problem solution,in order to meet the high-speed communications,emergency safeguard in high-speed mobile scenarios,such as car communication demand for highly reliable network service.During the SMR(Smart Mobile Router)networking,traditional manual configuration cannot meet the fluctuation of high-speed mobile networks and the diversity and complexity of configuration requirements,resulting in low deployment efficiency and slow network networking of SMR devices.SMR devices need to dynamically establish tunnels in complex mobile scenarios.Existing protocols,such as dynamic host configuration protocol and zero configuration network service specification,are only applicable to the configuration of host addresses with reliable network transport services in the same network segment,and cannot meet the requirements of dynamic tunnel establishment of SMR devices.In addition to the requirements of automatic configuration,SMR devices have long distance mobility and high reliability requirements for network services,which make existing network configuration service solutions unable to meet their needs.Aiming at the above problems,this paper designs and implements a dynamic tunnel management system for smart integration device in complex mobile scenarios.The whole system is divided into five modules according to the functions.The distributed server module is responsible for maintaining the networking,disaster recovery and multiactivity of the server.This paper proposes a dynamic tunnel management distributed hyper fusion remote multi-activity and disaster recovery server architecture,which realizes the high availability of tunnel parameter management server.The multi-link transmission module is responsible for message transmission between the dynamic tunnel management client and the server of SMR devices.In this paper,multi-link fastest response Dr(MFRD)algorithm is proposed.The dynamic tunnel establishment module is responsible for the client to request the tunnel network parameters from the server.This paper designs the fastest Service First(FSF)algorithm.During the request process,the client chooses the server with the fastest response to serve the client.The tunnel address pool module is responsible for maintaining the tunnel address pool and realizing the persistent storage,allocation and recovery of the tunnel address.This paper innovatively proposes the concept of locking the tunnel address,which effectively avoids the tunnel address conflict between distributed servers.The configuration module automatically implements various configuration requirements of SMR devices,reducing the probability of configuration errors and improving the networking efficiency of SMR devices.Finally,the functions and performance of dynamic tunnel management system for smart integration device in complex mobile scenarios is tested.The functional test results show that: first,the dynamic tunnel management system designed can realize the dynamic tunnel management of integration device.Secondly,the system supports automatic networking,Disaster recovery,and multi-active functions on the server.The distributed server can smoothly expand capacity and cope with emergencies.Finally,the system realizes the multi-link cooperative transmission of the client and the server,and enhances the reliability of the message interaction between the client and the server.The performance tests show that the designed system can complete a dynamic tunnel establishment in an average time of about 300 ms when the packet loss rate is 50%.Therefore,the designed dynamic tunnel management system can well adapt to the highspeed moving scenarios of SMR devices. |
