Embodiment Construction

[0032] SDN network includes SDN network equipment (switch) and controller (Controller), such as figure 1 Shown. The Switch includes two functional components, SDN Channel (Management Channel) and Flow Table (Flow Table). Among them, the Switch establishes a connection between the SDN Channel and the Controller, usually based on SSL (Secure Sockets Layer) security. The SDN protocol (for example: OpenFlow protocol) is used for message interaction on the secure channel, so that the Controller can control the Switch, such as adding, deleting, and modifying flow tables, querying statistics, and forwarding packets through the Switch; at the same time, The Switch also reports its own status and various external events it senses to the Controller through the secure channel, so that the Controller can understand the changes in the network operation status. For terminals connected to the Switch, the Switch forwards packets according to the flow table.

[0033] It can be seen that the secu...

Abstract

A startup method is described in which a software defined networking (SDN) network device sends a request to a server to obtain controller address information and channel information and configures SDN parameters in accordance with the controller address information and the channel information and establishes a secure channel with the controller.

Description

Technical field [0001] The present invention relates to the technical field of network communication, and in particular to a method and device for realizing zero-configuration startup of SDN (Software Defined Networking) network equipment. Background technique [0002] With the rapid development of Internet technology, the number of services carried by the network is increasing, the types of services are becoming more and more complex, and the network scale is also increasing. This makes the network ills caused by the functional design defects based on the traditional network architecture increasingly obvious. In response to these problems, SDN came into being. SDN regards all network devices in the network as managed resources, and abstracts the network operating system (Network OS) by referring to the principles of the operating system. On the one hand, it shields the specific details of the underlying network devices. It also provides a unified management view and programming ...
