Simulation of Method of HGU User Side Interface Flow Information Transmission
Because there are too many side interfaces connecting different users,the distribution of interface flow information was unbalanced,leading to long information transmission and high packet loss rate.In this paper,a method of flow information transmission of HGU user-side interface was put forward.At first,an undirected graph and conflict graph were drawn for the user side interface of the Home Gateway Unit(HGU)to determine the transmission distance of flow information and thus to judge whether the transmission links interfere with each other.Based on the link flow model,a service model was built to calculate the load rate of the transmission link.In the particle swarm op-timization algorithm,the fitness function was adopted to update the position coordinates of particles,thus achieving a reasonable distribution of network traffic and maximum efficiency of transmission.Experimental results show that the network delay of the proposed method is always less than 0.10s,and the packet loss rate is controlled between 30%-45%.In addition,this method has higher throughput.
