Network architecture based on cloud computing and virtual network management method thereof

Abstract

The invention relates to the technical field of cloud computing networks, particularly a network architecture based on cloud computing and a virtual network management method thereof. The network architecture based on cloud computing is implemented by three-layer virtualization: access layer virtualization, core layer virtualization and virtual machine virtual network. Access layer virtualization: virtualizing network resources on the access layer, thereby implementing the functions of bandwidth allocation, IP (Internet Protocol) address allocation, security access control and the like. Core layer virtualization: virtualizing core layer network devices, and directly intercommunicating service nodes and a service node and a storage node. Virtual machine virtual network: implementing a virtual network card and a virtual switching machine in a computation node. The virtual network card implements connection through the virtual switching machine, and is communicated with an external network. The invention solves the problem in managing the cloud computing network resources through three-layer virtualization technology, and improves the network performance; and the invention can be widely used in virtual networks.

Description

technical field [0001] The invention relates to the field of cloud computing network technology, in particular to a network architecture based on cloud computing and a virtual network management method thereof. Background technique [0002] Cloud computing is to deliver computing resources, storage resources, network resources, etc. to users through the Internet in the form of services. To achieve this goal, a very complete data center must be established on the upper layer to host several application service platforms. In this way, the upper-level cloud computing data center must be very stable, because once the upper-level cloud computing service center fails, it is very likely that all cloud computing services will be interrupted. In order to ensure the stability and scalability of the data center, a three-layer network structure is usually used when building a data center network and two or more switching routing nodes are set between layers. On the one hand, it is to i...

AI Technical Summary

Problems solved by technology

The network delay caused by this situation is not very obvious at present, because there are not many business services running on the current data center

When cloud computing is implemented, a data center may run thirty, forty or even more business services. At this time, if each data packet has to go through several disassembly / packaging processes, it will easily cause Network congestion, resulting in network delay
