Design And Implement Of Mobile Network Self-organizing System For Collaborative Network

Collaborative network is a solution based on the 973 Program "theoretical foundation research of Intelligent Collaborative Network" to address the problem of poor network performance in high-speed mobile scenarios which can meet the needs of highspeed rail communications and emergency communications for stable network services.Before the collaborative network can work normally,it is necessary to configure routing devices in different geographical areas.The multi-regional devices and complex manual configuration have caused problems of low deployment efficiency and slow network networking.The most basic configuration of routing devices in collaborative networks is to configure IP address and routing entries.The existing dynamic host configuration protocol,zero configuration network service specification and other protocols are only applicable to the configuration of the host user IP address in the same network segment,and are not suitable for the configuration requirements of multiple interfaces and multiple network segments of the routing device in the collaborative network.The existing routing protocols,such as routing information protocol and open shortest path first protocol,can only transmit routing update messages between physically adjacent routing devices,which can not meet the transmission requirements of routing update messages between routing devices located in different geographical regions in collaborative network.In addition,the connection relationship between the routing devices that establish tunnel connection in collaborative network is relatively solid.The connection relationship can only be modified manually,and can not be modified adaptively according to the load of tunnel routing equipment in the public network.To solve the above problems,this paper designs and implements a collaborative network multi-region mobile subnet self-organizing system.Divide the whole system into six modules according to different functions: The IP address pool module is responsible for maintaining an IP address pool to implement the allocation and management of IP addresses across network segments,effectively avoiding subnet conflicts;The IP address request module is responsible for requesting multiple IP addresses and solving the problem that the existing protocol cannot achieve the IP address acquisition of multiple interfaces and multiple network segments;In addition to generating routing information in the mobile subnet,the routing module can also implement routing updates between non-adjacent routing devices;By executing XML based configuration template,the configuration module can automatically realize various configuration requirements,reduce the possibility of configuration errors,and improve the deployment efficiency of collaborative network;The mobile switching module balances the load between the tunnel routing devices on the public network in the collaborative network through indicators such as CPU utilization and memory utilization to improve the overall performance of the network;The manual configuration module provides an interface for network administrators to manually configure to meet personalized configuration requirements.Finally,the designed multi-region mobile subnet self-organization system was tested for functions and performance.The function test results show that the designed selforganizing system can not only realize the configuration of multi-interface and multisegment IP addresses of routing devices,but also effectively avoid subnet conflicts in the network.Secondly,the system supports the transmission of route update messages to the non physical adjacent routing devices,and the routing update messages are transmitted to the routing devices in other geographical regions in the collaborative network.Finally,the system achieves load balancing among the tunnel routing devices located in the public network and strengthens the data processing capability in the collaborative network.All in all,the self-organizing system of the multi-region mobile subnet of the collaborative network can improve the networking efficiency,enhance the automation level of the collaborative network,and improve the collaborative network ecology.
