[Abstract]:With the rapid development and popularization of information networks, the expansion of network scale and the rapid increase of demand for various broadband services, the existing rigid, closed, complex, heterogeneous networks can not provide matching efficient dynamic network services. The flexible, open, simple and programmable software definition network (SDN) presents a new architecture and idea to solve the current network problems, in which OpenFlow is a kind of implementation protocol of the southern interface in the SDN architecture. At present, IP and optical transport network are controlled separately and have different architecture, switching technology and control management mechanism, so it is difficult to cooperate between IP layer and optical layer, so the network expansibility is poor, the efficiency is low and the resource utilization is low. The unified control of IP and optical transport network based on OpenFlow is studied in this paper. The unified control of IP and optical transport network as a whole is no longer hierarchical and independent, so that the unified cooperative network performance optimization can be extended. High efficiency and high resource utilization. This paper focuses on the key technologies of unified control of IP and optical transport network based on OpenFlow. The main research work is as follows: (1). The network architecture and control mechanism of unified control between IP and optical transport network based on OpenFlow are analyzed and designed. On the basis of the usual SDN architecture including application layer, control layer and data layer, the network architecture of unified control between IP and optical transport network based on OpenFlow is designed. The unified control mechanism including unified control packet switching and circuit switching, unified abstraction and uniform path control is analyzed and designed in detail under the unified control network architecture. (2) Based on the above unified control network architecture and control mechanism, the functional requirements of the unified control platform of IP and optical transport network based on OpenFlow are analyzed, and the overall scheme design of the unified control platform is completed. (3) The requirement analysis of the OpenFlow communication processing module of the unified control platform is completed. Based on the open source NOX controller, the OpenFlow communication processing module is designed and developed, which realizes the connection processing between the control platform and the node, receives and forwards the OpenFlow message and encapsulates the OpenFlow message. The feasibility of the module is verified by simulation test.
