Embodiment 1

[0051] Such as figure 2 As shown, this embodiment realizes the access of personal access users and enterprise users of the virtual network based on NVO3.

[0052] The core technical point of this embodiment is that, first, in the data center, according to the distribution of VN, select a suitable NVE (Network Virtualization Edge, network virtualization edge) equipment, according to the implementation mechanism of NVO3, NVE can be a top-of-rack Switch ToR, or VMM / Hypervisor (virtual machine manager) or other related network equipment, and connect all required related VMs to related NVEs, and perform related configurations on VNEs. It should be further explained that the preparation of the VM also requires a corresponding configuration process, usually through figure 1 Among them, the virtual machine provides and manages the system to configure and realize, specifically, apply / configure to generate a VM, and configure / set the MAC address and IP address of the VM as required. Se...

Embodiment 2

[0080] Such as Figure 4 As shown, this embodiment implements the access of existing VPN network users of the virtual network based on NVO3.

[0081] The difference between this embodiment and Embodiment 1 is that it is necessary to further use the NVE of the data center gateway of the virtual network generated in the data center as the CE device, and configure the PE device connected to the existing VPN. Specifically, configure the sub-interface / interface between CE and PE, including IP address selection and configuration between CE and PE, and configure routing protocol or static route on the interface.

[0082] Depending on the actual deployment strategy, the CE device can also select other NVEs of the VN. The specific configuration is the same as the above data center gateway NVE configuration.

Embodiment 3

[0084] This embodiment provides a method of combining implementation cases 1 and 2, which can be further extended to the application scenario of configuration and implementation of virtual networks based on MPLS VPN. Specifically, it includes configuration of PE devices related to the VN, and / or optional CE configuration. Specifically, it includes VRF configuration, CE-PE interface and configuration of supported protocols.

Abstract

A realization method of virtual network management and a virtual network management system of the present invention relate to the communication field. The method disclosed by the present invention comprises the steps of using a VN business development and management function entity to determine a VN parameter according to the VN disposition demands; using the VN business development and management function entity to obtain the available network resource information; if the available network resources satisfy the VN disposition demands, determining a mapping relationship of a VN and the physical network resource, determining a physical network device and a computer system needing to be configured; using the VN business development and management function entity to send configuration management commands to the network device and the computer system; using the network device and the computer system to execute the configuration management commands, and returning an execution result to the VN business development and management function entity. The present invention also discloses a virtual network management system. The application technical scheme can support the efficient businesses of cloud computing providers, and provides a universal VN automatic configuration scheme.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a virtual network management implementation method and system. Background technique [0002] With the widespread development of cloud computing services, the characteristics of cloud services are becoming more and more advanced. For example, early IaaS services generally provided separate computer resources and storage resources. However, what a cloud computing user often needs is that these computing and storage resources form a network to implement the user's application functions or provide / develop services. Furthermore, these resources are generally located in the data center of the cloud computing service provider. Cloud computing users also need to be able to achieve remote access through networks such as the Internet, or the networks of these customers in the data center can be connected to the user's current In some networks, especially in the user's en...
