Message broadcasting method and equipment

Abstract

The invention provides a message broadcasting method and equipment. The method comprises the steps that: a target host machine where a target virtual machine in the same broadcast domain with a local virtual machine is located is determined after a broadcast message isreceived from the local virtual machine; transforming the broadcast message into a unicast message, and sending the transformed unicast message to the determined target host machine, wherein the unicast message carries a broadcast domain identifier and a broadcast processing mark; after a virtual switch on the target host machine receives the unicast message, if the unicast message carries the broadcast processing mark, the unicast message is restored into a broadcast message, and a target virtual machine in the broadcast domain is determined from the virtual machines running on the target host machine, and the broadcast message is sent to the determined target virtual machine. By using the method provided by the invention, the occupation of the broadcast message on the network bandwidth is reduced while the message broadcast is realized, and the resources of the host machine equipment are saved.

Description

technical field [0001] The present application relates to the field of cloud computing, and in particular to a message broadcasting method and device. Background technique [0002] A cloud computing network usually includes: multiple hosts and intranet switches. The intranet switch can interconnect multiple hosts. Each host runs a virtual machine and a virtual switch. The virtual machine is used for business processing, and the virtual machine switch is used for communication between local virtual machines and cross-device communication of virtual machines. [0003] In a cloud computing network, multiple virtual machines (such as multiple virtual machines on different hosts, or multiple virtual machines on the same host) form a virtual data center, and each virtual data center is isolated from each other. Users can apply for a virtual data center for business processing. [0004] Under this architecture, when the user's business involves broadcasting the message in the v...

[0005] However, in practical applications, since a broadcast domain contains a small number of virtual machines (such as a few or a dozen), and the number of hosts in the cloud computing network is huge (such as thousands to tens of thousands) , which makes a large number of hosts in the cloud computing network have no virtual machines in the broadcast domain, and this broadcast method will cause a large number of hosts that do not need this broadcast message to receive the broadcast message and respond to the broadcast message. On the one hand, the device resources of these hosts are wasted, and on the other hand, there are a large number of broadcast messages in the cloud computing network, which greatly occupies the network bandwidth.
