Research of QoS hierarchical adaptive tactic based on mobile Internet
基于移动互联网的QoS分级自适应策略研究

The QoS hierarchical adaptive tactic based on real-time emergent management was proposed, using the method of hierarchical mapping table to establish the QoS mapping relationship between mobile network and Internet. And the selecting algorithm on QoS of multi-operation and aggregation stream was put forward as well, using the gateway linked to Internet as the decision-making node of adaptive QoS modulating. The gateway supervised the change of network load. According to the operation stream QoS was modulated timely which made decision timelier. The simulation results show that the tactic solves the problem of the match-mapping between mobile network and operation QoS which Internet provides, reduces the transportation delay over 20%, and restrains the users from enlarging their needs blindly and avoids the aggravation of the network burden caused by the users attack viciously.
