摘　　要：由于连接不同用户的侧接口过多,导致接口流量信息分配不均衡,造成信息传输时长较长、丢包率高等问题。为解决上述问题,提出HGU用户侧接口流量信息传输方法。通过对家庭网关单元(Home Gateway Unit,HGU)用户侧接口构建无向图和冲突图,确定流量信息传输距离以及各传输链路之间是否互相干扰;以链路流量模型为基础构建业务模型,得到传输链路负载率;在粒子群优化算法中,利用适应度函数更新粒子的位置坐标,实现合理分配网络流量,实现最大效率的传输。实验结果表明,所提方法网络时延始终保持在0.10s以下,整体丢包率控制在30%-45%之间,且具有较高的吞吐量。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 optimization 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.
