Embodiment 1

[0053] A kind of realization method based on OpenFlow virtualization network Qos, described method concrete steps comprise:

[0054] The S1 intranet switch guides the outbound traffic of the virtual machine to the OpenFlow node;

[0055] S2 traffic enters the OpenFlow controller through the Ingress port;

[0056] The S3 flow table uses IP matching to limit its flow through the set bandwidth;

[0057] The S4OpenFlow node converts the traffic of the internal network and the external network to each other;

[0058] The S6 intranet core switch sends traffic to the target virtual machine to realize Qos traffic control;

[0059] When using the method of the present invention to realize network Qos, firstly, the outbound flow of the virtual machine according to S1 passes through the internal network core switch, and the internal network switch guides the outgoing flow to the OpenFlow node, and then the flow enters the OpenFlow controller through the Ingress port according to S2, an...

Embodiment 2

[0081] A kind of realization system based on OpenFlow virtualization network Qos, described system comprises diversion module, guidance module, current limiting module, conversion module and control module:

[0082] Drainage module: the intranet switch guides the outbound traffic of the virtual machine to the OpenFlow node;

[0083] Boot module: traffic enters the OpenFlow controller through the Ingress port;

[0084] Current limiting module: the flow table uses IP matching to limit its current through the set bandwidth;

Abstract

The invention discloses an implementation method and system based on OpenFlow virtualization network Qos, and belongs to the field of private cloud computing. The method comprises the following specific steps: S1, an intranet switch guides virtual machine network outgoing flow to an OpenFlow node; S2, the flow enters an OpenFlow controller through an Ingress port; S3, the flow table uses IP matching to limit the flow through the set broadband; S4, the flow of the intranet and the flow of the extranet are mutually converted by the OpenFlow node; S6, the intranet core switch sends the flow to the target virtual machine to realize Qos flow control; according to the method, a Qos universal implementation mode is provided for the private cloud based on the OpenFlow technology, universal user Qos flow speed limitation is achieved, the bandwidth utilization rate and the management and control flexibility are improved, fine management of the tenants on the bandwidth is achieved, dependence of a third-party hardware firewall on Qos implementation is avoided, and the private cloud deployment efficiency is greatly improved.

Description

technical field [0001] The invention discloses a method and system for realizing network Qos based on OpenFlow virtualization, and relates to the technical field of private cloud computing. Background technique [0002] With the rapid development of Internet technology, various new services and protocols have emerged one after another, such as OSPF, BGP, NAT, MPLS, VPN, OpenFlow and so on. With the gradual addition and continuous updating of these services, the pressure on network equipment is also increasing, becoming more and more bloated and difficult to continue to improve, and some disadvantages in IP networks are gradually revealed, which makes the development of IP networks emerge. bottleneck. However, when there are disadvantages and bottlenecks in the network field, the computer field has achieved rapid development and is becoming more and more perfect. This is because the computer field adopts the X86 instruction set and a common hardware bottom layer. Based on t...
