Embedded Nms Design And The Rabbit Processor

The thesis disserts the requirement analysis of embedded network management system,hardware system and software system design,and realization based RABBIT system.The important part is the realization of embedded Web server and reduction in TCP/IP protocol. The user can manage the network element through accessing the Web server. When the server is accessed correspoding CGI program can be called to implement network management work,then the user can manage the communication equipment through IP network.After completed the requirement analysis of embedded network management system,the thesis disserts the realization of static and dynamic modeling in UML, hardware system design with RABBIT2000 processor,PCA9564 IIC controller etc accoding to system's function requirement. About software design,the thesis disserts the reason of selecting the μC/OS-Ⅱ as the operation system after analysed and compared the task scheduling method- in Dynamic C and μC/OS-Ⅱ. Furthermore,some key technique such as HTTP, ICMP, TCP, IP protocols are analysed, file system FS2,watchdog,communication command,IIC communication, rating security management are designed. Task's creation is on the principle of high cohesion and low coupling ,and its priority is set according to the importance. All state machine's design are comply with the necessity of system, mutual command and data structure are created according to the circuit board's parameter and alarm information.The system is realized based on RABBIT2000 processor and dynamic C compiling environment. At last, the system is evaluated comply with ITU-T M.30xx regulation.
