IPv4与IPv6头部之比较

传统的互联网协议IPv4协议存在地址空间匮乏、路由效率不高、安全性差、对移动性支持不好等缺点,严重阻碍了Internet的发展,下一代互联网协议IPv6彻底解决IPv4上述难题。     

Performance of intelligent Mobile IPv6

Mobile IP is the current standard proposed by IETF for mobility management in IP networks. Mobile node communicating with static correspondent node (CN) has been considered in previous performance studies. We propose the mobility of CN and two additional mobility combinations for Mobile IP in this paper. CN mobility causes performance degradation in an environment with frequent handoffs. A new scheme for Mobile IPv6 called Intelligent Mobile IPv6 is proposed. It is observed through simulation results that the performance of Intelligent Mobile IPv6 is better than Mobile IPv6.     

一种改进的IPv4/v6网络入侵检测技术研究

IPv6较IPv4有很多优势,如几乎无限的地址空间、自动配置机制、简化的报头结构、内置IPScc协议、扩展报头以及对流标签的支持等。基于网络应用日益丰富,而网络安全的威胁无处不在,人们越来越重视网络通信的安全,入侵检测系统已经得到了非常广泛的应用。伴随着IPv6时代的到来,借鉴IPv4环境下入侵检测的架构,综合利用协议分析技术、网络审计技术,并结合双找技术,提出一种改进型IPv4/IPv6环境下入侵检测系统模型,期望能在IPv6环境中提供高效、准确的网络攻击等行为的检测服务。
