说明：  season解答的关于在NS仿真中出现的比较棘手的问题，这些问题中的很多问题在NS仿真中都会出现，而且如果对ns理解不深入的话很难及时解决，NS高手season详细解答了这些问题，在ns仿真中会起到事半功倍的效果。
(season to answer on the NS simulation appears more difficult issues in many of the problems in the NS simulation will occur, but if ns does not understand the depth resolved in a timely manner, then it is very difficult, NS masters season to answer these questions in detail, in ns simulation will play effectively.)
