摘要
基于 ATM的无源光网络 ( APON)为分布式媒质共享结构 ,所承载业务的 Qo S要求各异 ,如何在保证系统传输效率的同时满足用户对服务质量的需求 ,是 APON接入控制算法的关键 .文中提出了分布式分层调度方案 ,为各类业务提供不同的 Qo S保证 ,并通过仿真对业务的时延和时延抖动特性进行了分析 .结果表明 ,该算法优于 Global
ATM based Passive Optical Network (APON) has become an important broadband access medium. APON is a distributed system with shared medium, so the MAC research is focused on how to meet the diversified QoS requirements while still keeping transfer efficiency. A distributed hierarchical scheduling scheme was proposed with simulation on delay and jitter performance. The result indicates that our scheme has better performance than Global FIFO.
