Problems solved by technology

[0002] With the development of the cloud platform, the collection and statistics of traffic in the cloud platform has become the focus of research. There is research on the statistical method of virtual machine external network traffic on the cloud platform, which is aimed at the external network traffic on the virtual router on the cloud platform collection, but there is no method for collecting link data between virtual machines in the cloud platform, which involves a variety of links, including virtual links within the host machine, virtual links across host machines, and virtual and real links. Interlinks, etc., need to provide a data collection method that can collect diverse links of the cloud platform

Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and embodiments.

[0039] The flow chart of this embodiment is as follows figure 1 As shown, the technical scheme is as follows:

[0040] S1: Build the basic environment of the OpenStack cloud platform. OVS is selected as the virtual switch when building, and the network node Network and the control node Controller are built separately. This embodiment includes 2 network nodes Network and 7 computing nodes Compute. The specific number of network nodes and computing nodes can be designed according to the experimental needs.

[0041] S2: On the OpenStack platform, build a target simulation network, including network nodes and network links. The network nodes include physical nodes and virtual nodes. Virtual links, virtual and real interconnected links.

[0042] S3: In the target simulation network built, the link is expressed as a set as follows...

Abstract

The invention discloses a link data collection method oriented to network simulation, relates to the technical field of the network simulation, and implements diverse links including a virtual link ina host machine and a virtual link between cross-host machines in an OpenStack platform as well as distributed collection and storage of virtual and real interconnected links. The method comprises thesteps of constructing a basic environment of an OpenStack cloud platform; constructing a target simulational network including three links on the OpenStack platform; expressing the three links with sets; deploying an overall configuration analysis program and a collection program; selecting a link in need of being collected and configuring, and identifying a target port using the deployed overallconfiguration analysis program; performing setting of port mirroring on multiple ports located on a same computing node; and starting a data collection program and storing collected data in real time. By providing the data collection method oriented to the simulational network and storing the collected data in real time, a data support is provided for an application research of a third party.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a link data collection method oriented to a simulation network. Background technique [0002] With the development of the cloud platform, the collection and statistics of traffic in the cloud platform has become the focus of research. There is research on the statistical method of virtual machine external network traffic on the cloud platform, which is aimed at the external network traffic on the virtual router on the cloud platform collection, but there is no method for collecting link data between virtual machines in the cloud platform, which involves a variety of links, including virtual links within the host machine, virtual links across host machines, and virtual and real links. It is necessary to provide a data collection method that can collect diversified links of the cloud platform. [0003] As a typical cloud platform, Openstack has become the first choice fo...
