Embodiment 1

[0109] After the cloud management user logs in to the cloud platform through a VM and wants to create an access link to the external network, see image 3 In the flow of the shown network processing method, the cloud platform performs the following specific steps 300 to 306:

[0110] Step 300, acquire the external network identifier of the external network for which the access link is to be created and the type of virtual device to be created in the above access link.

[0111] Here, when the cloud management user wants to create an access link of the external network, the cloud platform will display the pre-configured external network list to the cloud management user, so that the cloud management user can choose from the external network list to create an access link and after the cloud management user selects the external network ID, the creation selection box of various virtual device types virtual devices will pop up to the cloud management user, so that the cloud manageme...

Embodiment 2

[0182] see Figure 5 As shown in the structure of the SDN controller, this embodiment proposes an SDN controller, which is used to execute the network processing method executed on the SDN controller side in Embodiment 1 above.

[0183] The SDN controller includes:

[0184] The receiving module 500 is configured to receive a creation request sent by the cloud platform for creating an access link between the private network and the external network. The creation request includes: virtual device type, external network identifier, gateway information, and device resource pool identifier, wherein, The above-mentioned gateway information and the above-mentioned device resource pool identifier are determined by the above-mentioned cloud platform according to the above-mentioned external network identifier;

[0185] A determining module 502, configured to determine, from the device resource pool corresponding to the device resource pool identifier, the forwarding device that creates...

Abstract

The invention provides a network processing method, a cloud platform and an SDN controller. A forwarding device determined according to an external network identifier in a device resource pool is configured according to gateway information and an interface address determined based on the external network identifier, an access link between a private network and an external network corresponding tothe external network identifier is created, corresponding access links are created for all external networks, so that traffic generated in access of the external networks by a private network user canbe sent to external networks through corresponding access links, traffic is isolated when the private network user accesses different external networks, and the private network user can access the external network more safely.

Description

technical field [0001] The present application relates to the technical field of tenant networks, and in particular, to a network processing method, a cloud platform, and a software-defined network (Software Defined Network, SDN) controller. Background technique [0002] At present, network operators use software-defined networking (SDN) network virtualization on physical networks to establish private networks belonging to different enterprises, thereby virtualizing a physical network into different private networks. It enables enterprises to meet their internal office and operation needs without purchasing servers, establishing network architecture, and directly renting private networks established by network operators. [0003] The private networks established by network operators for different enterprises are not aware of each other and cannot communicate with each other, so that the traffic between private networks is isolated. However, the traffic generated by each ent...
