  1. 每个结点 i 上保持两个向量: 时延向量 Di={di1, di2, di3,……diN}, dij为结点 i 致结点 j 的最小时延 的当前估值,(dii=0) 后继结点向量Si={si1,si2,si3…..siN},sij,从结点 i 到结点 j 的当前最小时延 路由中结点 i 的后继结点 每隔128ms,每个结点与它的所有相邻结点交换它们的时延向量。然后根据 收到的全部时延向量来修改本结点的时延向量和后继结点向量。对结点k dkj=Min[dki+dij] iA, A为结点k的所有相邻结点的集合 skj=I,用这个i使得[dki+dij]最小

  2. 问题:假定某一时刻到达C的向量如下,结点顺序是 A,B,C,D,E,F From:B(5, 0, 8, 12, 6, 2); D(16, 12, 6, 0, 9, 10); E(7, 6, 3, 9, 0, 4); 而从C测量出到B,D,E的时延分别为 6,3和5,试计算结点C新的路由表,和给出 C到各结点的下一站路由。 2 B C 4 3 A D 5 1 6 7 E F 8

  3. dkj=Min[dki+dij] iA, A为结点k的所有相邻结点的集合; skj=I,用这个i使得[dki+dij]最小 C测量出到B,D,E的时延分别为 6,3和5 C-B----A 6+5=11 C-E----A 5+7=12 C-D----A 3+16=19
