Embodiment Construction

[0020] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0021] figure 1 Network diagram for voice VLAN configuration. as, press as figure 1 The shown topology builds a network, connects an Internet Protocol (IP) phone (Phone) to a switch, and its MAC address is 00:04:67:00:00:05.

[0022] figure 2 Configure the automatic mode for Voice VLAN. Such as figure 2 Configure the user as shown, the steps are as follows:

[0023] a) Create VLAN 100 and VLAN 200;

[0024] b) Add an OUI whose value is: 00:04:67:00:00:00 / 24;

[0025] c) Configure the aging time of Voice VLAN as 100 (unit: minutes), and users can also set it according to their needs;

[0026] d) Enter interface 1 / 1;

[0027] e) Set the virtual LAN ID number (pvid) of the port to 100;

[0028] f) adding the interface to VLAN 100 corresponding to pvid;

[0029] g) Enable the Voice VLAN function ...

Abstract

The invention discloses a data transmission method used for a Voice VLAN (virtual local logic network). The method comprises the steps that A, a port enables the Voice VLAN and sends a data package to a central processing unit (CPU) and registers a package receiving manipulation function to the CPU; B, a received data package is judged according to the packet receiving manipulation function, if the data package meets the preset conditions, the port corresponding to the data package is added into the Voice VLAN and such data packages are transmitted in the Voice VLAN in the mode of high priority, wherein the preset conditions are that the data package has a Voice VLAN Tag and a source MAC is matched with an OUI; and C, the ports enabling and listed into the Voice VLAN are traversed at fixed time in a task mode and aged ports are logged out from the Voice VLAN. By adopting the data transmission method used for the Voice VLAN, the MAC does not need to be enabled for learning, the Voice VLAN port does not need to be added by reading a forwarding table, and the method adopts a package CPU mode, and has the advantages of convenient search and good system real time property.

Description

technical field [0001] The invention relates to data communication and VoIP (Voice over IP) technology, in particular to a data transmission method for voice (Voice) virtual local area network (VLAN, Virtual Local Area Network). Background technique [0002] Voice (Voice) virtual local area network (VLAN) is a VLAN divided for the user's voice data flow. By creating a voice VLAN and adding the interface connected to the voice device to the voice VLAN, the voice data flow is concentrated in the voice VLAN for transmission. Voice VLAN is used to facilitate targeted QoS (Quality of Service) configuration for voice data streams, so as to improve the transmission priority of voice data traffic and ensure call quality. The interface works in automatic mode, and when the source Media Access Control (MAC, Media Access Control) address in the data stream entering the interface is a recognizable Organizationally Unique Identifier (OUI, Organizationally Unique Identifier) ​​address, t...
