基于动态通道绑定的更高速无源光网络

摘要：传统无源光网络单通道速率提升成本越来越高，多通道无源光网络通过多通道绑定实现速率提升。由于业务的多样性，基于通道和时隙的动态通道绑定逐渐成为研究和标准化方向。本文分析了现有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，提供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。

Abstract: Multiple channels PON could achieve higher bandwidth capacity and dynamic channel bonding could further meet service diversity. This paper analyzes the requirement and function of dynamic channel bonding in current IEEE and ITU-T PON standards and the existing problems. This paper further provides a transmission method including serialization transmission and order recovery for dynamic channel bonding in Higher Speed PON. This method simplifies dynamic channel bonding processing and avoids the problem of bandwidth efficiency degradation.
