With the rapid development of mobile internet applications
software de?nition network) technology will play an important role in 5 G network
especially in the evolution of IP RAN network. In this paper
the shortcomings of traditional DPI analysis system are analyzed. SDN technology is proposed to realize mobile service sensing acquisition and monitoring
and the technical scheme is given. Through this scheme
we can collect and analyze the mobile Internet traf?c under the condition of greatly reducing the deployment cost. This scheme can locate faults in time
detect the use of resources
schedule resources reasonably and improve the utilization rate of resources.
