Problems solved by technology

However, the current SDN controllers and Openflow switches mainly handle the forwarding of Layer 2 data packets, while the forwarding support for Layer 3 routing functions is less, which limits the application of SDN technology in traditional networks
[0004] In order to solve the problem of traffic interworking between the current SDN network and the traditional network, some academic institutions have proposed a method to add three-layer routing

Example Embodiment

[0033] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0034] The embodiment of the present invention provides an SDN platform based on router virtualization. The SDN platform is located on a server. The SDN platform includes a virtual router, an Openflow switch, and an SDN controller. The implementation method of the SDN platform includes the following steps:

[0035] S1. Install virtual routers, Openflow switches and SDN controllers on the X86 server. See figure 1 As shown, the VMware software and SDN controller are installed on the Windows system of the general X86 server, and the virtual router image and Openflow switch are installed in VMware. The virtual router runs on a general X86 server platform, and realizes the characteristics of network flexibility advocated by the separation of control and forwarding in SDN technology.

[0036] See figure 1 As shown, the SDN controller includes an east-west int...

Abstract

The invention discloses an SDN (Software Defined Network) platform based on router virtualization and an implementation method, and relates to the field of virtualization technology, SDNs and cloud computation. The SDN platform comprises a virtual router, an Openflow switch and an SDN controller, wherein the SDN controller comprises an eastbound-westbound interface, a northbound interface, a first southbound interface and a second southbound interface; the second southbound interface is used for controlling data packet forwarding of the virtual router, and recording flow entry information of the virtual router; the first southbound interface is used for learning routing topology and a flow table of the second southbound interface in order to control rapid forwarding of the Openflow switch; and an application programming interface (API) layer based on an Openflow protocol is encapsulated on an integrated code layer of the virtual router. Through adoption of the SDN platform based on the router virtualization and the implementation method, high data forwarding performance and routing performance between an SDN network and a conventional network can be realized. The virtual router has the characteristics of high functional extensibility and high flexibility, and can be applied to the cloud computation easily.

Description

technical field [0001] The invention relates to the fields of virtualization technology, SDN and cloud computing, in particular to a router virtualization-based SDN platform and an implementation method. Background technique [0002] The current popular cloud computing and SDN (Software Defined Network, software-defined network) technologies are all related to virtualization technology. The original intention of virtualization technology is to achieve efficient utilization of general hardware platform resources and flexible deployment of network devices, while SDN technology is to realize the separation of control layer and forwarding layer, and the realization of the forwarding layer is generally based on Openflow switches. [0003] The SDN controller determines the packet forwarding of the Openflow switch, and the Openflow switch can be implemented in various ways, including software or hardware. However, the current SDN controllers and Openflow switches mainly handle the...
