Problems solved by technology

Real-time services such as VOIP put forward higher requirements on message transmission delay. If the message transmission delay is too long, users will not be able to accept it.
[0003] The traffic control in the traditional network is based on some basic tools. The original traffic controller TC (TrafficControl) is used for the traffic control of the Linux kernel. It mainly realizes the traffic control by establishing a queue at the output port. The control method is based on Routing, and browsing control based on the network number of the destination subnet based on the destination IP address. In addition, configuring the traffic controller needs to establish queues, classifications, filters and routes. The setting environment is more complicated, and there are problems based on the QoS of the Openstack cloud platform. At present, many cloud computing vendors are developing IAAS cloud computing platforms based on openstack

Embodiment Construction

[0023] The present invention is further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 As shown, increase the storage of the average flow and peak value when the network is newly created, store the average flow and peak value in the database, use this network when creating the cloud host, read the bandwidth limit parameters when the network is newly created, and call the packaged script At this time, after the cloud host is created, a port will be generated, and the name of the network card corresponding to this port on the br-int bridge will be used to obtain the bandwidth limit parameters. If you want to set the average traffic and peak value, you can call the Openvswitch method again For setting, the method of calling Openvswitch for setting is as follows:

[0025] 1) Create QOS, create maximum speed limit

Abstract

The invention discloses virtual machine port speed limitation and mirror methods in a private cloud. An IAAS cloud computing platform for the private cloud already has the leading security and stability and plays a large role in the field of cloud data centers; the platform implements network traffic bandwidth limitation of a virtual machine based on a network technology of an openvswitch, and copies a message of a designated port to another port connected with a network monitoring device on a switch using a function provided by an SPAN via a route information message of the virtual machine for network monitoring and trouble removal to realize a traffic mirror method.

Description

technical field [0001] The invention relates to the speed limit and mirror image of a virtual machine port, in particular to a method for speed limit and mirror image of a virtual machine port in a private cloud. Background technique [0002] Quality of Service (QoS) is very important in today's data communication networks, whether in LAN or WAN. In a traditional IP network, all packets are treated indiscriminately, and each forwarding device adopts FIFO (first in, first out) for all packets, and it tries its best to send the packets to the destination, but It does not provide any guarantee for the reliability of message transmission, transmission delay and other performance. But in practical applications, there are big problems in the network, such as bandwidth, packet loss rate, network delay and congestion, etc. With the development of the network, these problems have greatly affected network services, such as (VOIP, IPTV, etc.). Real-time services such as VOIP put for...
