Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0038] See image 3 As shown, the present invention constructs the data forwarding plane of the virtual router and includes the following basic steps:

[0039] Step 1 S10: The physical router obtains the information for establishing the data forwarding plane of the virtual router sent by the virtual network management center VNC.

[0040] Before the physical router obtains the above information, VNC needs to perform the following steps to generate the above information:

[0041] 1. The user generates his own virtual network topology and the related attributes of each virtual router, and the user submits a request to VNC to establish a virtual network;

[0042] 2. VNC generates a virtual network identifier VNID for the virtual network;

[0043] 3. VNC...

Abstract

The invention discloses a method and a system for constructing a data forwarding plane of a virtual router. The method for constructing a data forwarding plane of a virtual router is implemented based on a VLAN (virtual local area network), and comprises the following steps that: a physical router acquires information (for establishing the data forwarding plane of the virtual router) sent by a virtual net management center so as to generate the virtual router, distributes a first link identifier to a first link between each line processing card and the virtual router, and respectively distributes a second link identifier to a second link between the line processing cards and the line processing cards, so that the life cycle of the data forwarding plane of the virtual router begins. According to the invention, the purpose that the data grouping is performed without changing the data structure thereof in the data forwarding plane and forwarding process of the virtual router with a guaranteed bandwidth is achieved, and the support of a common Ethernet switch board card on the virtualization technology is realized.

Description

technical field [0001] The invention relates to a router virtualization technology in Internet network equipment, in particular to a method and system for constructing a data forwarding plane of a VLAN-based virtual router. Background technique [0002] Over the past few decades, the Internet has achieved great success, providing us with a new way of exchanging information. The surge in the size of the Internet has stimulated the large-scale deployment of various network technologies. Due to the huge Internet industry chain, it is difficult to deploy new architectures, which affects Internet innovation. Network virtualization provides a solution to break this impasse. The entire network is divided into infrastructure providers and service providers. The service provider rents the facilities of the infrastructure provider and builds a VN (Virtual Network, virtual network) for the user to meet the different needs of the user. Each virtual network has its own identifier, na...
