Problems solved by technology

However, when there are a large number of PC server devices, for example, for a data center with hundreds of thousands of computers, and each computer may virtualize dozens of virtual machines, if the VN is still manually configured, the configuration The workload is huge, and due to the dynamic existence of VMs joining and leaving the VN, the development of VN services becomes complicated

Embodiment Construction

[0070] The present invention provides such an implementation scheme for developing the network as a service. And, further, because the data center network is generally concentrated in the operator's computer room, which is far away from ordinary users, it is necessary to connect customers to the data center, so that the virtual network has wider practicability, which is generally through broadband network to achieve.

[0071] The basic idea of ​​the present invention is: set a VN-AP in the data center network or / and broadband network, receive the user's VN service request through the service development and management functional entity, and generate the characteristic information of the VN; PC / VM performs VN-AP AP automatic discovery, when the PC / VM is authenticated by the VN, the automatically discovered VN-AP generates the VN forwarding table entry of the PC / VM and encapsulates it through the tunnel according to the VN forwarding table entry , to forward the message from th...

Abstract

The present invention provides a method and a system for realizing virtual network (VN), and said method comprises: virtual network access point (VN-AP) is set in a data center network or / and a broadband network; a service development and management function entity receives a VN service request from a user and generates characteristic information of said VN; PC / VM processes automatic discovery of VN-AP and after the PC / VM identity is authenticated by the VN, the automatically discovered VN-AP generates the VN forwarding table item of the PC / VM and forwards messages from the PC / VM through tunnel encapsulation according to the VN forwarding table item. The present invention enables automatic and rapid establishment of the VN by automatically discovering the VN-AP used for managing the VN.

Description

technical field [0001] The invention relates to the field of broadband communication, in particular to a virtual network realization method and system. Background technique [0002] In recent years, cloud computing has become a hot spot in the information industry. In the context of cloud computing, software as (i.e.) business / service (SaaS), infrastructure as (i.e.) business / service (IaaS), platform as (i.e.) business / service (PaaS) have become hot businesses, and there are Everything as a Service (XaaS) trend. Under the influence of the idea of ​​XaaS, compared with the idea of ​​power system development (users only use electricity, and do not need to build power plants for power supply), it is possible to provide network-as-a-service services for small and medium-sized enterprises and even large-scale enterprise networks, that is, each This kind of network for enterprise users is also provided by service providers, not just network operators providing network connection...
