Embodiment Construction
[0099] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.
[0100] Such as figure 1 As shown, a method for collecting important node information in an SDN environment includes the following steps:
[0101] S1 selects parameters that can effectively reflect the importance of forwarding nodes based on the nature of the SDN framework and on the basis of ensuring scalability. The parameters include four categories: 1) communication volume; 2) network topology; 3) activeness of forwarding nodes; 4) network service information. Among them, the first three items of data are selected according to the interface provided by the standard communication protocol Openflow in the SDN framework and th...
