摘要 针对乒乓切换(移动节点频繁地在PAR和NAR间频繁切换)时,现有的预测式FMIPv6存在着时延大、丢包率高、信令冗余等问题,该文提出了一种新的解决方案,定义了新的Hop-by-Hop选项报头TM,PCoA表和双向隧道表,并将TM捎带在NAR向PAR发送的最后一分组数据包的确认中,告知PAR,MN将不久会移回PAR域,以便PAR提前准备好其与NAR之间以前建立好的双向隧道,从而达到MN的快速和平滑切换。分析表明,该方案能有效地解决上述问题,提高移动用户的QoS。 This paper proposes a novel scheme based on pingpang handoff (mobile node's frequent handoff between PAR and NAR) for predictive fast handovers for mobile IPv6 to solve the problems of long latency, high lost packets and excessive signaling redundancy in exiting schemes. It defines a new Hop-by-Hop option header named TM, PCoA table and tunneling table. TM is put in the acknowledgement of the last packets between NAR and PAR, telling PAR that MN would be back to the region of PAR in the near future, and hoping that the previous bidirectional tunneling between PAR and NAR is available, so that MN could implement its fast and smooth handovers. Analysis shows that this scheme is viewed as an effective method to solve the above problems and can improve the quality of service for mobile users.
