Design And Implementation Of The Network Management System For The Hybrid Network

The traditional communication network is usually composed of fixed communication devices and wired connections between them.In this case,this network always can't covere in remote areas,and it may cause network disruption when sudden natural disasters occur or man-made disruptions occur.By rapidly setting up the communication vehicles and using LTE as the wireless transmission,mobile network can serve as a supplement or extension of a fixed network to protect the main business is not affected when the network is damaged.With the development of communication technology,the hybrid network mentioned above is gradually applied in military,government,disaster relief,medical and other fields.Hybrid network with fixed communication devices and communication vehicles has high maneuverability,different communication devices,various kinds of complex and dynamic network topo connection,found and manage the network equipment by artificial is unrealistic.Therefor a network management system is urgen need to comprehensively control the hybrid network and the devices in it.Using the network management system to found the hybrid network,monitor network in real-time,statistics the historical performance and process the real-time alarm,provides the technical support for managers who manage the hybrid network.This paper focuses on the design of communication interface between the network management system and the devices,and how to configure the interface quickly in the network management system.The main contents of this paper include:1?Design interface to found the hybrid network.The UDP protocol is make for transferring a small amount of data at one-time.According to the characteristics of hybrid network transmission is unstable with narrow network bandwidth,design the multiple transmission with a small amount of data flow to found the network,and to develop a network founding standards based on the UDP protocol.So we can found the hybrid network fast and accurate with the network management system.2?Design interface to monitor the hybrid network.In order to reduce the huge network management information generated by the SNMP poll-job,designing the basic interaction process of network monitoring and using decode module which simplifies state information to monitor the network.Through formulating interface standards between the management system and devices,the network management system shield the differences brings from different manufacturers and different devices.3?Design internal Annotation.According to the management interface designed between network management system and devices,design the internal annotation process in management system and use the Annotation technology as the data configuration of business information.Using Annotation achieve rapid configuration for different business requirements.In this case,the management system improves scalability.4?Implementation and verification the management system.With the design pattern of MVC,the network management system is implemented by using SSH architecture.After that,show the main usage of the system through examples,which verifies the feasibility of the system design.In this paper,a network management system for the hybrid network is designed,which provides a solution for the network founding rapidly and network monitoring comprehensive.
