摘要
传统无源光网络单通道速率提升成本越来越高。多通道无源光网络可通过动态通道绑定实现速率提升,进一步满足服务多样性需求。分析了现有IEEE和ITU-T无源光网络标准中的动态通道绑定需求和功能实现,以及数据传输过程中存在的带宽效率、数据顺序恢复等问题,提出了一种更高速无源光网络动态通道绑定中数据序列化传输和顺序恢复方法。该方法简化了动态通道绑定处理,避免了带宽效率下降问题。
The cost of single channel rate improvement in traditional passive optical networks(PON)is increasing.Multi-channel PON could achieve higher bandwidth capacity by dynamic channel bonding and could further meet service diversity.The requirement and function of dy⁃namic channel bonding in current IEEE and ITU-T PON standards and the existing problems are analyzed.A transmission method including serialization transmission and order recovery for dynamic channel bonding in higher speed PON is provided.This method simplifies dynamic channel bonding processing and avoids the problem of bandwidth efficiency degradation.
