摘　　要：为了提升网络带宽容量、降低网络时延,提出基于资源利用率的可重构无源光通信网络。通过可重构平台的网络管理构件、数据采集构件、P2P重定向构件共同配合,建立可重构无源光通信网络,依据可重构无源光通信网络层间信息互通特点,在网络物理层上添加MAC层,设计基于MAC-RPON层的资源分配模型,MAC层依据用户队列内调度事宜轻重程度,将所有队列数据包按照优先级别排序,物理层通过可重构无源光通信网络的准入、带宽分配和频谱分配三个步骤,将子载波合理分配给每个用户。实验分析表明:所研究网络可有效完成资源分配,且网络带宽容量大,更好地满足资源合理利用需求;网络平均队列长度短,资源分配时延低、效率快,有效提升网络资源利用率。In order to improve network bandwidth capacity and reduce network delay,a reconfigurable passive optical communication network based on resource utilization is proposed.The reconfigurable passive optical communication network is established through the cooperation of the network management component,data acquisition component and P2P redirection component of the reconfigurable platform.According to the information exchange characteristics between the layers of the reconfigurable passive optical communication network,the MAC layer is added to the network physical layer,and the resource allocation model based on the mac-rpon layer is designed.The MAC layer sorts all queue data packets according to the priority according to the degree of scheduling matters in the user queue,The physical layer reasonably allocates subcarriers to each user through three steps:admission,bandwidth allocation and spectrum allocation of reconfigurable passive optical communication network.The experimental analysis shows that the studied network can effectively complete the resource allocation,and the network bandwidth capacity is large,which can better meet the needs of rational utilization of resources;The average queue length of the network is short,the delay of resource allocation is low and the efficiency is fast,which can effectively improve the utilization of network resources.
