Abstract: Disclosed is a method for processing downlink signalling of an SDN virtualization platform based on OpenFlow. The method comprises: after the preprocessing of downlink signalling is executed, further executing same, so as to judge whether more Match items also exist in a Match item list; if it is judged that more Match items also exist, acquiring an item from the Match item list; if it is judged that there are no more Match items, ending the processing; after completing the step of acquiring an item from the Match item list if it is judged that more Match items also exist, further judging whether more Action items also exist; if there are no more Action items, combining a new Action item list with the Match items to generate downlink signalling, and issuing same to a virtual network switch; and returning to the step to continue judging whether more Match items also exist; and if more Action items also exist, acquiring the next Action item.
