摘　　要：为了应对互联网数据流量和业务类型的变化,网络设备和网络架构都需要不断演进,光传送网(OTN)设备也不例外。近些年,OTN交叉粒度逐渐丰富和完善,在一定程度上满足了多业务的传送需求。但是为了应对快速增长和复杂多变的数据业务,OTN交叉技术需要与数据交换技术相结合,才能更高效更经济地满足未来多业务传送需求。In response to the changes in Internet traffic and diverdified services,network equipment and network structure need also to be adjusted,of course including optical transport network（OTN） equipment.In recent years,different OTN switching units has been developed to meet the multi-service transport requirement.However,to fulfill the future ever fast growing multi-service transport requirement efficiently and economically,OTN switching should be combined with packet switching,which is also the future direction of the OTN equipment evolvement.
