Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The present invention provides a data push method, which is applied to multimedia teaching, referring to figure 1 , in the first embodiment of the data push method of the present invention, the data push method includes:

[0043] Step S10, when receiving the data push instruction sent by the first node, the proxy node joins the second node on the network segment where it is located and associated with the identification information to the multicast group based on the identification information carried in the data push instruction ;

[0044] The data push method proposed in this embodiment can be applied to multimedia teaching. For example, the remote teacher end (first node) pushes the multimedia data to the far-end agent end (agent node) by unicast, and the agent end The multimedia data received by it is pus...

Abstract

The invention discloses a data push method, and the method comprises the steps that an agent node enables a second node, correlated with the recognition information, of a network segment to be added to a multicast group based on the recognition information carried by the data push instruction when a data push instruction transmitted by a first node; the agent node receives a data flow transmitted by the first node in a unicast mode; the agent node transmits the data flow to each second node in the multicast group in a multicast mode when the data flow is received. The invention also discloses a data push device. The method can reduce the implementation difficulty of network segment crossing multicast.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a data push method and device. Background technique [0002] In modern multimedia teaching and other scenarios, teachers and students are generally assigned a computer, and then the application information (including desktop, audio and video, etc.) The computers used by the students are under the same switch or router, and it can be realized through multicasting. However, if the computers used by the teacher and the computers used by the students are not under the same switch or router, especially in the desktop virtualization scenario, the teacher Both the teacher and the students are connected to their own virtual machines through the terminal, and then the application information of the virtual machine needs to be broadcast to the student terminals. All the switches or routers that pass through from the computer to the student terminal are multicast sett...
