CORD Build 2017

In the era of 5G, CORD in the edge of metro network will aggregate a variety of different services which require the huge and on demond of bandwidth,different SLA guarentee,Differentiated services provisioning. The interconnection network between CORDs should support network slicing, bandwidth on demand, and AI based controll. Here we want to present a new architecture-Slicing Packet Network, which can provide the end-to-end phisical layer isolation and packet switch. It can provide DWDM based optical layer(L0), 64b/66b block based coross connect(L1) , Ethernet switching(L2)+Segment Routing(L3). It is Disaggregated Transport Network.With SDN controller such as ONOS, It can replace the triditional OTN/ROADM and the routers in metro network in the future. China Mobile and their partners have verified it in Lab.
