Hello,
do you know some link where is good explained backward learning algorithm? (bridges use this algorithm)

thanks

Answer : backward learning algorithm

backward learning
 
Technical Definition:
      Algorithmic process used for routing traffic that surmises information by assuming symmetrical network conditions. For example, if nodeA receives a packet from nodeB through intermediate nodeC, the backward-learning routing algorithm assumes that A can reach B through C optimally.
