Embodiment Construction

[0114] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0115] Before introducing the link flow control method provided by the embodiment of the present invention, the implementation environment involved in the embodiment of the present invention will be introduced first. The embodiment of the present invention is applied to a DC network. A DC network usually includes multiple hosts and at least one switch. Each host is deployed with one or more virtual machines. External communication devices between different virtual machines or between virtual machines and the DC network communication between them is possible. Moreover, multiple communication links can be formed between the host and the switch and between the switches according to the topology, so the DC network also includes multipl...

Abstract

The application discloses a link traffic control method and device, belonging to the technical field of virtualization. The method includes the following steps: monitoring the traffic load of each communication link in multiple communication links included in a data center network, wherein the traffic load is a ratio of the link traffic of each communication link to the link bandwidth; when determining that a target communication link is overloaded based on the traffic load of the target communication link, determining a target virtual machine to be migrated from virtual machines that generatethe link traffic of the target communication link, wherein the target communication link is any one of the multiple communication links; determining a target host from other hosts included in a target cluster other than the host where the target virtual machine is located, wherein the target cluster is a host cluster where the host of the target virtual machine is located; and migrating the target virtual machine to the target host to further control the link traffic of the target communication link. Thereby, the problem that some communication links have packet loss due to the excessive load, and business damages are caused can be avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of virtualization, and in particular to a link flow control method and device. Background technique [0002] With the development of computer technology, virtualization technology has been more and more widely used in data center (Data Center, DC) network. A DC network usually includes multiple hosts and at least one switch. Each host is deployed with one or more virtual machines. Communication can be performed between different virtual machines or between virtual machines and external communication devices of the DC network. During the communication process That is, a large amount of communication traffic will be generated. In addition, in a DC network, multiple communication links will be formed between the host and the switch and between the switch and the switch according to the topology structure, and the link traffic on each communication link is related to the deployment loc...
