一种PMIPv6快速切换路由优化方案
|
摘要
代理移动IPv6协议中,所有的数据都需经过本地移动锚点的转发,导致本地移动锚点的负担加重；若移动节点和通信节点处于相近的网络位置,由于数据传输仍然要通过本地移动锚点,就会导致传输路径冗余,降低了网络传输的效率。本文针对代理移动IPv6协议中存在的数据传输问题,指出了采用路由优化传输模式的必要性,分别对移动节点发生域内和域间切换时重建路由优化路径的问题提出了不同的解决方案,主要研究内容如下：
1.介绍了移动IPv6的发展现状,指出了当前基于移动终端的移动IPv6协议的不足,深入的研究了代理移动IPv6协议相关技术及基本原理,对现有的代理移动IPv6域内和域间的切换管理方案进行了研究分析。
2.将代理移动IPv6路由优化方案与移动节点发生域内切换的情景相结合,提出了域内切换后重建路由优化路径的改进方案,新方案由移动接入网关预先发起路由优化过程,相比原方案减少了本地移动锚点的参与。性能分析和仿真实验结果表明改进后域内路由优化方案在切换开销和切换时延方面都优于原有方案。
3.对目前研究较少的代理移动IPv6域间切换场景进行分析,同时提出一种基于快速切换思想的域间路由优化方案,新方案能够在切换发生前预先发起优化路径的建立,并通过移动接入网关之间信令的交互来建立它们之间的双向隧道。通过性能分析和对仿真实验结果的比对,基于快速切换的域间路由方案能够带来更小的切换开销和切换时延。
路由优化是代理移动IPv6协议研究的重点,移动节点通过路由优化路径进行通信,不仅能够减少数据传输的时延,还能够充分利用网络资源,减少对信道的占用。本文提出的域内和域间路由优化方案均采用了快速切换的思想,在移动节点即将发生切换时就发起路由优化路径的重建,能够有效的降低切换的时延；同时整个路由优化过程均由移动接入网关发起,减小了切换过程中的开销,减轻了本地移动锚点的负担。
In Proxy Mobile IPv6protocol, all data are required to pass through the forwarding local mobile anchor, this will lead to increased the burden on local mobile anchor point; if the mobile node and the communication node is similar to the network location, because the data transmission is still going through the local mobile anchor, this would result in the transmission path redundancy, reduce network transmission efficiency. To solve the problem of data transmission in the Proxy Mobile IPv6protocol, this paper points out the necessity of using routing optimization transmission mode, and proposes different solutions of the mobile node's routing optimization paths of intra-domain and inter-domain handover reconstruction, the main research as follows:
1. Introduces the development status of Mobile IPv6, pointes out that the current lack of Mobile IPv6protocol which is mobile terminal based, and gives an in-depth study of the related technologies and the basic principle of Proxy Mobile IPv6protocol, then analyzes the existing Proxy Mobile IPv6intra-domain and inter-domain handover management approaches.
2. Combines the PMIPv6route optimization approach with the mobile node's intra-domain handove scene, proposes the improved approach of reconstruction route optimization path after intra-domain handover, in the new approach, mobile access gateway initiates the route optimization process in advance, compared to the original approaches; new approach reduces the participation of the local mobility anchor. Performance analysis and simulation results show that the improved intra-domain routing optimization approach is better than the original approach in handover cost and handover delay.
3. Analyses the scene of Proxy Mobile IPv6inter-domain which is few studies at present, at the same time, proposes an inter-domain route optimization approach based on fast handover, new approach can establish the optimal path in advanced before mobile node's handover, and through the signaling interaction between mobile access gateways to build bidirectional tunnel between them.Through the comparison of performance analysis and simulation results, the inter-domain route optimization approach based on fast handover can bring the smaller handover cost and handover delay.
Route optimization is the focus of the research in Proxy Mobile IPv6protocol, mobile nodes communicate through the routing path, this not only can reduce the delay of data transmission, but also can make full use of network resources, reduces the occupancy of the channel. In this paper, the intra-domain and inter-domain routing optimization approached both use the idea of fast handover, initiates the reconstruction of the route optimization path when the mobile node's handover occurs, reduces the handover delay effectively; and aslo, the entire route optimization process is initiated by the mobile access gateway, reduces the handover cost, reduces the burden of local mobile anchor.
