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;
[0085] Conversion module: OpenFlow nodes convert intranet and extranet traffic to each other;
[0086] Control module: the intranet core switch sends traffic to the target virtual machine to realize Qos traffic control;
[0087] When using the method of the present invention to realize network Qos, first, the outbound traffic of the virtual machine through the drainage module passes through the core switch of the internal network, and the internal network ...
