摘　　要：EPON和WiAMX的融合架构提供了一种低成本、高带宽和高覆盖的接入网的解决方案。EPON和WiMAX有着不同的服务质量(QoS)体系模型,对于融合架构来说,如何建立统一的带宽分配策略,实现区分多业务和保证QoS是需要面对的一个问题。文章设计了一个融合网络下的带宽分配框架,详细分析了带宽申请和分配的过程,并给出了具体的算法设计。The convergence network of EPON and WiMAX is cost-effective, high-bandwidth and high coverage area solutions for future access network. EPON and WiMAX belong to different QoS model, so how to construct a unified bandwidth allocation scheme, distinguish between various services and provide QoS assurance for the convergence network are common problems. In this article, we proposed a bandwidth allocation framework for the convergence network and elaborate on the process of bandwidth application and allocation. Future more, we provide the detailed algorithm design.
