Problems solved by technology

In related technologies, the gateway of the SDN network can be a hardware gateway (for example, Core Switch), but the hardware gateway does not support the deployment of services such as IPSec and Firewall. When these services are needed, they need to be deployed separately outside the SDN network; increased service deployment The complexity reduces the convenience of network deployment

Embodiment Construction

[0024] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.

[0025] The embodiment of the present application provides a composite gateway in an SDN network, and the composite gateway is composed of a hardware gateway and a software gateway. Such as figure 1 As an example, the combined gateway can use the hardware gateway 11 as an interface for communicating with the external network (for example, a Wide Area Network, WAN), for example, the traff...

Abstract

The invention provides an SDN-based gateway configuration method and an SDN controller. The gateway configuration method is used by the SDN controller for configuring a combination gateway. The combination gateway comprises a hardware gateway and at least one software gateway. The method comprises the following steps: according to IP address and forwarding configuration information of a host in an SDN, determining a software gateway in charge of forwarding a message for the host from the at least one software gateway, wherein the forwarding configuration information comprises a preconfigured corresponding relation between network segment information including the IP address and the software gateway; issuing a host router for the software gateway; and issuing a first inter-gateway forwarding router for the hardware gateway communicating with the software gateway so as to enable the hardware gateway to forward the message whose destination IP is the IP address, sent by an external network, to the software gateway according to the first inter-gateway forwarding router, wherein the router comprises the IP address of the host and gateway information of the corresponding software gateway. According to the invention, the disposition complexity of the SDN is reduced, and the convenience is improved.

Description

technical field [0001] The present application relates to communication technology, in particular to an SDN-based gateway configuration method and an SDN controller. Background technique [0002] Software Defined Network (SDN) is an implementation of network virtualization, which realizes flexible control of network traffic by separating the control plane of network equipment from the data plane. In related technologies, the gateway of the SDN network can be a hardware gateway (for example, Core Switch), but the hardware gateway does not support the deployment of services such as IPSec and Firewall. When these services are needed, they need to be deployed separately outside the SDN network; increased service deployment The complexity reduces the convenience of network deployment. Contents of the invention [0003] In view of this, the present application provides an SDN-based gateway configuration method and an SDN controller, so as to reduce the deployment complexity of ...
