| With the rapid development of Internet recent years, it is growing demand of the Internet, the Internet also bring more and more convenient for us. In this condition, Internet-based applications has grown day by day, VoIP is one of them. Because the VoIP is Internet-based, it's price is very low. After the generation of VoIP, it has been rapid worldwide development and expansion. With the speeding up of the integration of television and telecommunications network, VoIP development and popularity will move to a new level in China. Due to its characteristics of openness, VoIP will be rapid development in China, but it also brings some problems. Because of the platform on the Internet, the VoIP may be subjected to attacks such as SPIT and DoS. So, with its rapid development, we also to safeguard its security, VoIP monitoring system was born in this environment.VoIP is difficult to do the content analysis. SPIT has become an important security threat. In this condition, we propose a framework and communication formats to achieve this system.VoIP monitoring system is a complex system, including voice traffic load balancing, distributed monitoring, session meta-analysis, offline processing, data storage, user control operation module. How to coordinate in this system is a problem to be faced. This paper analysis and design of this problem, the following key elements:First:This paper presents a system architecture based on CORBA. The structure of the original distributed intrusion detection system based on the expansion of its architecture model. The CORBA technology to achieve a combination of different functional modules. ORB middleware technology control using the entire system, so that the system development and operation of each module regardless of platform, coding language, hardware and status differences, only the parts to communicate with the central node to get all the information and data. At the same time to achieve each function module with the central node of communication content and communication. The program applies to VoIP voice monitoring system, can solve the heterogeneous platform, communication mechanism is not uniform and so on. Second:The design of the VoIP communication detailed format of the detection system. According to the task of the whole system and the system is dynamic and open, this design of the system message format. This message format uses a REST architectural style, system communication can be achieved without the state. To solve the dynamic changes in the system nodes, each node adaptive functional changes, the system interact with the central node and each node communication needs. Implementation of the software architecture style, the dynamic changes in the module is to solve the problem of the system, the communication process and the system no status.Third:This paper designed a system control interface. According to the function of the system implementation, to meet the user controlling the entire system and the purpose of showing the entire user interface has been designed. Including the entire system each node of the state, artificial control of single or batch run of all nodes, the system reports the results show and so on. End users and monitoring, and can view the entire sub-user access control the system running VoIP and data. Finally design a voice detection system model garbage. |
