if the response request instruction is consistent with the response request instruction, mapping the response request instruction based on a preset first mapping table; otherwise, judging that the forwarding path can not be normally used;
when the mapping processing result is that the response request instruction and the mapping address of the first mapping table are mapped with each other, judging that the forwarding path can be normally used;
otherwise, judging whether a branch node mapped with the response request instruction exists in the mapping topology tree or not based on a preset mapping topology tree;
if yes, determining all branches formed by root nodes and leaf nodes corresponding to the branch nodes, and calculating the response granularity of each branch;
if not, judging that the forwarding path cannot be normally used;
according to a priority sorting rule, performing priority sorting on the calculated response granularity of each branch, and determining whether the optimal response granularity is larger than a preset granularity or not;
if yes, judging that the forwarding path can be normally used;
otherwise, judging that the forwarding path can not be normally used.
10. The method of claim 1, wherein the main and auxiliary path allocation of the first forwarding path and the second forwarding path is determined according to the transmission stability probability of the first forwarding path and the second forwarding path, and the specific steps are as follows:
step 1, determining the transmission rates of the first forwarding path and the second forwarding path;
wherein S is1Is the transmission rate of the first forwarding path, C1The signal width of the first forwarding path is N, and the N is the number of transmission network packets;
wherein S is2Is the transmission rate of the second forwarding path, C2The signal width of the second forwarding path is N, and the N is the number of transmission network packets;
step 2, obtaining the stable transmission probability of the first forwarding path and the second forwarding path;
wherein ξ1For a stable transmission probability, S, of the first forwarding path1The transmission rate of the first forwarding path is t, and t is preset time;
wherein ξ2Is a stable transmission probability, S, of the second forwarding path2The transmission rate of the second forwarding path is t, and t is preset time;
step 3, determining a main path and an auxiliary path according to the stable transmission probability of the first forwarding path and the second forwarding path;
when xi1＞ξ2when the first forwarding path is a main path, the second forwarding path is an auxiliary path, and when xi is1＜ξ2And if so, the first forwarding path is a secondary path, and the second forwarding path is a primary path.
