【摘要】 随着下一代网络的发展,各大运营商积极实行软交换商化的同时,如何提供一个安全可靠的网络是网络建设过程中所必须要考虑到的问题,尤其对于软交换这样一个运营系统而言,安全问题显得尤为重要。由于软交换网络的研究是刚刚发展起来的领域,所以目前这方面的研究还不够成熟。以软交换为核心的下一代网络一直是研究的热点,不仅设备制造商投人大量的金钱和人力研发设备,而且移动运营商也开展大量的测试和实验。用来验证设备的稳定性、协议的标准化程度以及规模组网的可行性。本文的研究目标就是针对软交换中的安全隐患,提出软交换的安全解决方案,对软交换的网络安全起到了一定的保护作用,实现了IPSec和NAT的兼容以及NAT在软交换网络中的穿越。最后以贵州移动网络为例,提出软交换在贵州移动网络改造建设中的应用方案和网络安全的具体解决方案,设计方案具有良好的可操作性。本文以软交换中网络安全技术为研究方向,第一章对课题的背景、研究的动向和研究的内容进行分析;第二章为软交换技术的概念、功能结构、网络结构、接口、协议进行论述;第三章是对软交换的网络安全隐患进行论述,研究了具体安全解决方案;第四章以贵州移动网络为例论述安全组网在实际中的效果;第五章对全文作出总结和研究展望。更多还原

【Abstract】 With the development of the NGN, while all the operators commercialize the Softswitch, how to provide a secure and reliable net will be the matter that must be considered in the construction of network. As for the operating Softswitch system, security appears especially important. Because of a new scientific research on Softswitch, there is not much study on it. The research focuses on Softswitch which is the core in NEN. Not only did the equipment manufacturers spend a large amount of money and manual work on developing equipment, but mobile operators did a large number of tests and experiments on this technology. The purpose is to test its constancy, the standard degree of agreement and the feasibility of the scale group net.The target of the study is to work out the problem of the security with Softswitch and make combination IPSec with NAT, and make NAT used in the network with Softswitch. At last, taking Guizhou mobile network as example, the study suggests the project of applying Softswitch in the reconstruction of Guizhou mobile network, and the specific project of solution to the problem of net security. The design of the project is well-operative. This essay is based on the research on net security technology with Softswitch. The first chapter is to analyze the background of the program, the tendency and content of the research. The second chapter is to dissert the conception of Softswitch technology, function, net structure, interface, and agreement. The third chapter is also to dissert the feasibility of security of net with soft-switch and is about the specific solution to the problem of security. The fourth chapter is about, taking Guizhou mobile network as example, the factual effect of safe group net. The fifth chapter is to draw a conclusion and the research expectation of the whole essay.更多还原
