| With the rapid development of network hardware and software, the embedded system has been widely applied to all the fields of work and life. Embedded equipments that meet a certain special function become a leading factor in the pervasive computing era. As network technologies develop at a tremendous pace, the network has extended to the embedded field. Various embedded equipments can be connected to Internet, which compose the embedded network. Meanwhile, the embedded network offers a new challenge to network technologies. The issue of the embedded network management is one of the key technologies that embedded network technologies must resolve.SNMP is growing fast because of its outstanding simplicity and good expansibility. It gets much support from many manufactures and becomes actually the standard for network management protocol.The main task of this paper is that select the current popular S3C44B0X as the cpu to constitute the embedded system and design the network management system in CWDM embedded system based on SNMP.The basic concept and function of the network management are introduced briefly in the paper. With the development of the new technology, the development of the network management in embedded system is expatiated, including the domestic and foreign situation.The whole designment of network management in embedded system is introduced. The demand and the goal of design are introduced in firsrt. The construction of the system is proposed. The design ideal of each functional module is introduced finally.The hardware design of agent module in network management is introduced.The software design of system is introduced in emphasis,including the embedded software module in agent and application sotware module in manager. The Visual C++6.0 is used in the manager .The difficult in the software design is SNMP implementing. The SNMP module is designed according to the actual project situation. The receive and transmission based on SNMP is implemented.When this system is running,it can show the working status of embedded equipments and some network performance parameters. The long-distance monitoring and configuring is also implemented. |
