With the rapid growth and diversification of communication services, the heavy network and the unreasonable distribution of resource have become an urgent problem. Most of the existing technical equipment lacks of versatility,has a single function and there is no mechanism for controlling network resources. A scheme of 5G network slicing technology based on SDN/NFV is presented Using SDN centralized control theory,and NFV network virtualization theory, analyzing and researching the network pre-slice scheme based on multi-service and the traffic scheduling scheme based on network real-time situation. Among them,the network pre-slice scheme is studied,the result is transformed into queue information and deployed The traffic scheduling scheme is studied from the perspective of the inter-slice and the intra-slice, and the result is converted into a stream table item and deployed The SDN experimental platform was built,and the centralized control of the Open Flow protocol during resource control is verified by simulation. This paper completes the design of the multi-service network sliding scheme by redefining the virtualization of network environment and the redefinition of the software network.
