摘　　要：针对嵌套移动网络在快速移动场景和嵌套移动网络中的路由次优化问题及数据包多重封装问题,提出路由优化方案ERRHO。通过在反向路由头中新增槽位(Slot),对移动网络的最高层移动路由器(TLMR)的转交地址进行记录,使通信对端节点可以在首次收到数据包后就能够同TLMR进行隧道建立,最终完成嵌套移动网络内的路由优化。Aming at the long convergence time during route optimization after continual handoff and sub-optimal routing problem of the communication in intra-NEMO,new route optimization solution called ERRHO is proposed to solve sub-optimal routing problem caused by nested mobile networks.By adding new slot recording the care-of-address of the mobile router at the top of the nested mobile network（TLMR） in the reverse route header,the corresponding node can set up a bi-tunnel with the TLMR,then the route optimization between nested mobile network and corresponding node can be achieved.
