Embodiment Construction

[0021] see figure 1 with figure 2 As shown, a method for realizing double-network cross-segment access based on a single network card of the present invention comprises the following steps:

[0022] Step 1, provide a layer-3 switch and a terminal device, configure the virtual local area network VLAN of the layer-3 switch, so that the layer-3 switch can uplink access at least two different networks;

[0023] This step 1 specifically includes:

[0024] Step 10. Select two uplink ports on the Layer 3 switch, and name them as port 1 and port 2 respectively, set the VLAN ID of port 2 to 100, and keep the VLAN of port 1 as the default configuration;

[0025] Step 11. Connect the two uplink ports to two different networks respectively through a network cable; port No. 1 is connected to the first network of the two networks (such as network A: Internet), and port No. 2 is connected to two The second network in the network (such as network B: IPTV private network or company intrane...

Abstract

The invention provides a method for achieving double-network cross-network-segment access based on a single network card. Firstly, a three-layer switch and terminal equipment are provided, and a virtual local area network (VLAN) of the three-layer switch is configured so that at least two different networks can have upstream access to the three-layer switch; secondly, a downstream port of the three-layer switch is configured, two different network data can be transmitted to the terminal equipment through the downstream port; thirdly, network corrugation is performed by the terminal equipment, a VLAN card is virtualized, and at the moment, two sets of network card equipment exist; fourthly, a routing strategy is established, different network data are made to be transmitted to different networks, and therefore double-network cross-network-segment access is achieved. With the method, at least two networks can be communicated at the same time at any time; complexity for network deployment is reduced, and terminal cost and cost of the network deployment switch are reduced.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a method for realizing double-network cross-segment access based on a single network card. Background technique [0002] At present, on a terminal device, such as a converged cloud terminal, a personal computer, etc., to realize simultaneous access to two different networks, that is, physically isolated networks, two network cards are required, and two network cables are connected to different physical networks. However, most of the current terminal devices do not have two network cards. At this time, if you need to access two different networks through a single network card, you need to manually connect the upstream end of the network cable to a different network interface. This method is very inconvenient first, and secondly Simultaneous access to both networks of AB and AB cannot be realized. Installing dual network cards on the terminal will increase the cost...
