摘　　要：基于OIF(光互联论坛)协议标准,在业界首次建立了基于信元交换、能同时支持ODUk(k阶光通路的数据单元)交叉分组交换(交换容量大于10Tbit/s)的POTN(分组光传送网)系统,并进行了实际测试。测试结果满足POTN系统的ODUk抖动、时延和误码要求,以及数据业务的丢包和时延要求,验证了该技术的可行性和实用性。On the basis of the Optical Internetworking Forum (OIF)protocol standards,we establish for the first in the indus-try a cell switching-based Packet Optical Transport Network (POTN)system,which simultaneously supports the cross-con-nect and packet switching of the Optical Channel Data Unit k (ODUk)with a switching capacity of over 10 Tbit/s,and have it tested in practical projects.The test results indicate that this technology meet the requirements of POTN system in ODUk jit-ter,latency and bit error rate,and of data services in packet loss and latency,verifying its feasibility and practical applicability.
