Problems solved by technology

[0004] Since the message of the virtual machine does not pass through the computing node when it is forwarded, the computing node cannot filter the message of the virtual machine, so it cannot control the forwarding of the message of the virtual machine

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] SDN (Software Defined Network) is a new type of network communication architecture. SDN technology realizes centralized control and distributed forwarding of network devices. In the SDN technology, the network function is divided into two parts, the controller and the data channel, and the two parts interact through a secure channel. On the controller, the network devices controlled by it can be centrally managed, the network behavior can be uniformly arranged, and then the forwarding behavior of the data path can be specified. SDN technology greatly increases the controllability and flexibility of network management. At present, there are various technologies for the specific realization of SDN, among which the most mainstream is the OpenFlow (Open Flow) technology.

Abstract

The invention provides a virtual machine message control method and device. Applied to the OpenStack platform, a virtual network system is created through the OpenStack platform, and virtual network devices are virtualized in the virtual network system. The method includes: the OpenStack control node creates the port of the VM, and notifies the port UUID generated by the VM and the forwarding rules of the port application to SDN controller; after the VM is created in the virtual network system, the OpenStack control node receives the port ID of the VM queried by the OpenStack computing node; the OpenStack control node sends the corresponding relationship between the port ID of the VM and the port UUID of the VM to the SDN controller , the SDN controller generates a flow table according to the forwarding rules applied to the port, and sends the flow table to the virtual network device according to the corresponding relationship. The invention realizes the forwarding control of the VM messages.

Description

technical field [0001] The present invention relates to the technical field of OpenStack (open stack), in particular to a virtual machine (VM, Virtual Machine) message control method and device. Background technique [0002] OpenStack is an open source cloud computing management platform project that supports almost all types of cloud environments. OpenStack provides an infrastructure as a service (IaaS, Infrastructure as a Service) solution through various complementary services, and each service provides an API (Application Programming Interface, application programming interface) for integration. [0003] A standard OpenStack network generally consists of control nodes, network nodes, and computing nodes. The control node is the core of the OpenStack network, which manages network nodes and computing nodes. The control node controls the computing node to complete functions such as creating, starting and stopping the virtual machine. Virtual machines created by computin...
