According to the rapid development of network system, demands on internet quality are becoming stricter. The
traditional internet QoS routing manage mechanism can't meet high development on network bandwidth, transmission
delay, delay jitter, error rate and so on. Therefore, this paper designed a QoS manage mechanism based on AntNet, it
defined the exchange type in network and headed path finding algorithm, finally, after stimulate experiment in NS2
platform, it shows the model designed in this paper can enhance routing successful rate in both low level network load
and heavy level network load. The result gave a reference for researching on QoS routing manage mechanism.
