主机标识协议(Host Identity Protocol,HIP)是一种综合解决主机移动、多宿主及安全问题的有效方案,为了解决现有HIP机制在处理主机移动时存在切换延迟大、丢包率高等问题,提出了一种高效的基于HIP的移动性管理机制。该机制在基于HIP的层次化设计模型基础上,采用FMIPv6中的快速切换思想,引入了链路层触发机制、预先绑定更新机制和分组缓存转发机制。有效解决了移动主机在不同区域范围内的切换问题,降低了切换延迟和丢包率,改善了移动主机的切换性能,实现了透明、平滑、快速的网络切换。 相似文献

将宏观移动性管理的主机标识协议(HIP)应用于分布式移动性管理(DMM)构架,并将聚合服务器(RVS)与DMM中的移动性接入路由MAR功能集成于分布式接入网关(D-GW)。采用扩展HIP协议数据包头的参数,在注册D-GW的HIP BEX消息中携带切换前D-GW的主机标识符的二元组(HIT,IP地址),新D-GW根据此二元组信息向前一个D-GW注册并建立的隧道,将缓存在前D-GW中的数据转给新D-GW。这一切换机制可有效地保证数据完整性,仿真结果表明该方法能有效减少总的信令开销,同时基于HIP的移动性管理使节点的安全性得到了保证。 相似文献

本文提出了一种新的资源预留协议--移动资源预留协议(HMRSVP)。此协议建立在层次化移动IPv6(HMIPv6)框架与快速切换技术(FHMIPv6)基础之上。此协议能够让移动节点在进行子网间切换的时候获得更加平滑的切换性能。同时,本文还和现有基于HMIPv6和FHMIPv6的IntServ方案进行了性能比较分析。 相似文献

MIP协议为移动主机提供简单、扩展性强的全球移动,而各种micro-MIP协议则是解决域内快速、无缝切换的方案。当移动主机进行域间切换时,由于缺乏MIP协议与micro-MIP协议的协调机制将会导致移动主机的性能下降。提出了一种基于分组缓存和路由优化的宏观移动管理和域内micro-MIP协议无缝结合的新方案,可以提高All-IP网络的性能并保证移动主机的QoS性能。 相似文献

Mobility protocols allow hosts to change their location or network interface while maintaining ongoing sessions. While such protocols can facilitate vertical mobility in a cost-efficient and access agnostic manner, they are not sufficient to address all security issues when used in scenarios requiring local mobility management. In this paper, we propose a new scheme that makes Host Identity Protocol (HIP) able to serve as an efficient and secure mobility protocol for wireless heterogeneous networks while preserving all the advantages of the base HIP functions as well. Our proposal, called Heterogeneous Mobility HIP (HMHIP), is based on hierarchical topology of rendezvous Servers (RVSs), signaling delegation, and inter-RVS communication to enable secure and efficient network mobility support in the HIP layer. Formal security analysis using the AVISPA tool and performance evaluation of this method are provided; they confirm the safety and efficiency of the proposed solution. HMHIP reduces handover latency and packet overhead during handovers by achieving registration locally. 相似文献

With increasing societal dependence on the Internet and new application areas emerging, the need for securing communications and identifying communication partners is expected to increase. However, the original Internet architecture is lacking these functionalities, and most of the protocols proposed to fix these issues have not been widely deployed. Often one of the reasons for such failure is that protocol designers have insufficient understanding of the potential adopters’ economic incentives so one may end up designing protocols based on false or inaccurate assumptions. In this paper, we analyze the Host Identity Protocol (HIP) from this viewpoint. Based on 19 expert interviews, we identify six main reasons why HIP has not been widely deployed yet. Most importantly, (1) the demand for the functionalities of HIP has been low. Where demand would have existed, substitute solutions have been favored because (2) they were earlier on the market, (3) they have relative advantage due to some design choices of HIP, (4) HIP lacks early adopter benefits necessitating costly coordination among multiple stakeholders in public deployment scenarios, and (5) people have misconceptions about the deployability of HIP. Additionally, (6) the research-mindedness of HIP developers has lead to strategic mistakes and non-optimal design choices from the perspective of deployment. We also suggest strategies that HIP developers could take to foster the adoption of HIP. Besides providing value to HIP developers, the results propose some new adoption barriers and deployment strategies that could be taken into account when designing new protocols. Finally, the article also provides a template that could be followed when studying the feasibility of other protocols. 相似文献
