这个题怎么做?

这个网络路由算法我自己编了好久了,还是没有弄出来,大家帮帮忙!!!!!!!!

rules:
net1:no news, don't change
net2: same next hop, replace
net3:A new router add
net6:different next hop, new hop count smaller,replace
net8:different next hop, new hop count the same ,don't change
net 9:different next hop,new hop count larger ,don't change

每一个路由器 (net ,ip ,hop ,metric)
