As a mainstream solution for next generation optical access network

the TWDM-PON has the characteristics of high bandwidth

long distance

numerous access users etc.In order to effectively reduce the network delay and promote the fairness of resource allocation

an user-behavior aware dynamic resource allocation strategy is proposed for adapting to the increasing differences of user-behaviors in TWDM-PON.According to the dynamic traffic status brought by user-behaviors

the ONU polling mechanism is adjusted in real-time to satisfy the requirements of ONU service level.And the introduction of traffic sub-cycle can make the different grade service alternately send.Finally

for achieving multi-wavelength transmission of load balance

an efficient data block loading mechanism is designed.The simulation results show that the proposed strategy can reduce packet delay more than 50% and keep better fairness during resource allocation

while the utilization rate of network resource can reach 95%.
