Routing Service Design And Implementaion Of Openflow Network Testbed

With the developing of network technology, the traditional TCP/IP network becomes a more high-speed, open, intelligent direction, emerging a variety of new network technologies and protocols. However, due to the closed nature of the network, resulting in a lack of appropriate network technology verification platform, which impact the good development of network innovation.As most mainstream demonstrator platform of new network technology, network testbed which based on real network equipments has real hardware environment and real traffic support to meet the verification requirements of the part of the network innovation. However, the network testbed with traditional network interconnection equipment due to the lack of open architecture, which has limited support for new network technologies. As an implement of the SDN thinking, OpenFlow network technology can separate the control plane and the data plane from the computer network, so it becomes a viable technology for the formation of a network testbed.This paper is based on the OpenFlow network technology and designed to achieve given the existing routing protocol in the OpenFlow network, to achieve automated deployment of OpenFlow network, to achieve the connection of OpenFlow network and real network, to achieve routable network slices in OpenFlow network to meet the needs of different levels of network innovation. The first chapter has an introduction of OpenFlow and network testbed, the second chapter describes the deployment of OpenFlow network testbed and involved technologies, the third chapter gives the description of routing service design for OpenFlow testbed, the forth chapter gives the the description of routing service implement for OpenFlow testbed, the fifth chapter gives the test result of some key technological points, the sixth chapter is the summary and with the outlook for future work.
