摘要:
 身份与位置分离网络模型本身的特殊性,使得已有借鉴移动IPv6思想而设计的移动切换机制存在着某些弊端.移动终端发生切换后,通信对端只能在找到并确认身份信息与位置信息的映射关系后才能继续通信,否则通信将发生中断.为此,针对该网络中的切换机制,提出了"活跃对端"的概念,以确定移动终端与通信对端之间的绑定关系.当移动终端的位置信息发生变化时,移动终端主动向其所对应的活跃对端告知自己当前的位置信息.在此基础上,设计并实现了一种网络终端切换机制的优化方案,通过主动告知实现网络终端的自动切换.为验证所提出的方案,建立了基于该方案的实验环境并进行了改进后的切换机制测试,并就切换时延和信令开销等参数进行了对比分析.实验结果表明,优化后的方案能够有效提高网络切换性能,进一步提升通信效率.
Abstract:
 There are some drawbacks in the existing mobile handover mechanism designed by MIPv6 due to the particularity of Identifier/Locator Separation Network. After the MN has switched the CN should seek and confirm the mapping relationship between the identity in-formation and location information of the MN to continue communication with it,otherwise the communication can be interrupted. For the handover mechanism in the network,the concept of active node is presented to confirm the binding relationship between the MN and the CN. When the location information of the MN changes the MN actively informs its active node of its current location information. There-fore an optimization scheme of network terminal handover mechanism is designed and implemented for the achievement of automatic switching of network terminals through active notification. In order to verify it,the experimental environment is established and the testing of the improved handover mechanism is conducted as well as contrast analysis is carried on for the handover delay and signaling over-head. The experimental results show that it improves the performance of network switches and further promotes the communication effi-ciency.
