摘要
本文重点研究了无缝切换时的QoS问题,指出了这些技术的优点和不足,提出了对HMRSVP的改进方法。该方法通过设置RSVP阈值,采用被动预留资源机制,加强路由器的准入控制策略,有效地预测移动节点的移动,达到减小资源预留的时延,提高了多终端QoS保证的公平性,为用户提供了在移动IPv6的体系下端到端的服务质量保证。
Base on the discussion of the problem of RSVP under mobile scenario, this paper analyzes some existing proposals under the mobile environment and identify the advantages and drawbacks of them, then we proposed a new mechanism for integrating MIPv6 and RSVP using the advantages of Cross Router to improve the existing HMRSVP. Furthermore, Location predicts, Passive Reserve and Enhanced Admission control are introduced into the new model to provide seamless QoS guarantees.
