Ming Cheng, Zhou Zhou, Jun Zhu, et al. Research on Packet Enhanced OTN Equipment and Networking[J]. Dianxin kexue, 2014, 30(11): 159-165. DOI: 10.3969/j.issn.1000-0801.2014.11.027.
the packet enhanced optical transport network(POTN/PE-OTN)technology is able to meet the rapidly growing demand for bandwidth and multi-service bearing with differentiated quality of services. The statuses of POTN/PE-OTN technology standards were introduced. The architecture of POTN/PE-OTN equipment and the possible implementations were analyzed. The architecture of networking with POTN/PE-OTN technology in the metropolitan area network was discussed.
