Method and device for message broadcasting

Abstract

The present application provides a message broadcasting method and device, including: after receiving a broadcast message from a local virtual machine, determining a destination host where a destination virtual machine in the same broadcast domain as the local virtual machine is located; Transforming the broadcast message into a unicast message, and sending the transformed unicast message to the determined destination host; the unicast message carries a broadcast domain identifier and a broadcast processing flag. After the virtual switch on the destination host receives the unicast message, if the unicast message carries a broadcast processing flag, it restores the unicast message to a broadcast message, and in the virtual machine running on the destination host Determine a target virtual machine in the broadcast domain, and send the broadcast message to the determined target virtual machine. By using the method provided in the present application, while implementing message broadcasting, the occupation of network bandwidth by broadcast messages is reduced, and host device resources are saved.

Description

A message broadcasting method and device 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 connect multiple hosts to each other link. A virtual machine and a virtual switch run on each host. The virtual machine is used for business processing, and the virtual machine switch is used for It is used for communication between local virtual machines and cross-device communication between virtual machines. [0003] In a cloud computing network, multiple virtual machines (such as multiple virtual machines on different hosts, or the same host multiple virtual machines on the server) to form a virtual data center, and the virtual data centers are isolated from each other. Users can apply for virtual A data center is used for business proces...

Problems solved by technology

[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.
