Embodiment 1

[0024] Embodiment 1: as attached figure 1 As shown, the SDN and non-SDN intercommunication method includes the following steps:

[0025] Step S1, obtain an SDN network, the SDN network includes an SDN controller and an SDN device, load a virtual SDN network corresponding to the SDN controller and the SDN device in a virtual machine, and the virtual SDN network includes a virtual SDN controllers and virtual SDN appliances;

[0026] Step S2, sequentially inputting the port types and protocols of multiple non-SDN network devices into the virtual SDN network to obtain the entire network routing table of the virtual SDN network and non-SDN network devices;

[0027] Step S3, loading the entire network routing table into the SDN controller and SDN equipment, so that the SDN network and non-SDN network equipment can communicate with each other.

[0028] In Embodiment 1 of the present invention, the purpose of setting up the virtual machine is to not occupy the specific resources of ...

Embodiment 2

[0034] Embodiment 2: as figure 2 As shown, as a further optimization of embodiment 1, step S1 specifically includes:

[0035] Step S11, receiving a virtual machine creation request, the virtual machine creation request at least including processor information, memory information and operating system information;

[0036] Step S12, obtain the SDN controller and SDN device information, load the virtual SDN network corresponding to the SDN controller and the SDN device in the virtual machine, and run the SDN controller and the SDN device in the loaded virtual machine Corresponding virtual SDN controller and virtual SDN device.

[0037] In Embodiment 2 of the present invention, when executing a virtual machine creation request, it is necessary to match the operating environment according to the relevant operating information of the SDN controller, SDN equipment, and non-SDN network equipment, that is, processor information, memory information, and operation information. System ...

Embodiment 3

[0039] Embodiment 3: as image 3 As shown, as a further optimization of the above embodiment, step S2 specifically includes:

[0040] Step S21, establishing a queue about multiple non-SDN network devices, and sequentially acquiring the port type and protocol of each non-SDN network device in the queue;

[0041] Step S22, sending the port type and protocol to the virtual SDN device, so that the virtual SDN device can learn routing table items;

[0042]In step S23, after the learning of the routing table items is completed, the entire network routing tables of the virtual SDN network and non-SDN network devices are obtained.

[0043] In Embodiment 3 of the present invention, a plurality of non-SDN network devices are arranged in the form of a queue, and then the port types and protocols of the non-SDN network devices are obtained sequentially. This method can effectively avoid the situation of occupying more resources.

[0044] In practical applications, the port types and pro...

Abstract

The invention relates to the technical field of computer communication, in particular to an SDN and non-SDN intercommunication method and intercommunication system, and the intercommunication system comprises a virtual machine creation module, a whole network routing table generation module and a whole network routing table updating module. According to the SDN and non-SDN intercommunication method, during SDN and non-SDN intercommunication, specific resources of an SDN controller are not occupied, processing calculation of protocols, data and the like is firstly carried out in the virtual machine, the SDN controller does not need to participate in the whole process, and the SDN network is updated only after intercommunication in the virtual machine is completed, so the normal network use of a user is not affected, and the problem that when an existing SDN and a non-SDN communicate with each other, too many SDN controller resources are occupied, and consequently normal network use of a user is affected is effectively solved.

Description

technical field [0001] The invention relates to the technical field of computer communication, and relates to an intercommunication method and an intercommunication system between SDN and non-SDN. Background technique [0002] Generally, SDN (Software Defined Network, software-defined network) is a new type of network innovation architecture, one of the core technologies is Open Flow technology, which separates the control plane of network equipment from the forwarding plane, thereby realizing network flow The flexible control provides good technical conditions for the innovation of network applications. [0003] In the existing SDN and non-SDN interoperability process, the SDN controller needs to participate in the whole process to perform data calculation, command sending and receiving, etc., causing the SDN controller to be in a high occupation state for a long time, which greatly affects the normal network use of users . Contents of the invention [0004] The present...
