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
The present invention relates to communication apparatus technical field, relate in particular to a kind of method that realizes the access of dual network cross-network segment based on Single NIC.
Background technology
At present at a terminal equipment, as merged cloud terminal, on the equipment such as PC, realize two kinds of heterogeneous networks, i.e. access when physical isolation network, needs two network interface cards, by two different physical networks of the up access of netting twine.But not two network interface cards of most terminal equipments at present, if at this moment need to access two kinds of different networks by Single NIC, need manually netting twine upstream ends to be accessed to different network interfaces, this mode is first very inconvenient, access when secondly cannot realizing two kinds of networks of AB.For terminal, two network interface cards are installed, the one, meeting increases the cost of terminal, moreover owing to there being two up access switch of netting twine, the exchange interface of meeting serious waste, while making to access equivalent amount terminal, has increased again the cost of switch.
Prior art discloses a kind of " physical isolation control circuit and physical isolation Network Computer System " and has seen that publication number is: 1713581, within open day, be: the Chinese patent of 2005-12-28, it is a kind of switching that adopts Single NIC just can realize heterogeneous networks, thereby make unit can realize Intranet and the complete physically-isolated physical isolation control circuit of outer net, comprise microcontroller and the IDE control circuit being connected respectively with this microcontroller, network interface card circuit, control relay circuit, described network interface card circuit disposes multiple interfaces by described control relay circuit, the plurality of interface is for connecting respectively different networks.This invention also provides a kind of physical isolation Network Computer System that includes above-mentioned physical isolation control circuit.Adopt this system, Intranet sees through different networks from the data of outer net and connects transmission, invisible each other, and this has just improved the managerial and fail safe of data greatly.This invention has just realized the switching of heterogeneous networks, and realize at least two or more networkings by Single NIC in unrealized present patent application time access.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of method that realizes the access of dual network cross-network segment based on Single NIC, and any time now in fact, at least two kinds of networks can be communicated with simultaneously; Reduce the complexity of network design, and reduced the cost of terminal and the cost of network design switch.
The present invention is achieved in that a kind of method that realizes the access of dual network cross-network segment based on Single NIC, comprises the steps:
Step 1, provide a three-tier switch and a terminal equipment, the virtual LAN VLAN of configuration three-tier switch, makes the three-tier switch can at least two kinds of different networks of up access;
The downlink port of step 2, configuration three-tier switch, makes the data of two kinds of different networks be transferred to terminal equipment by this downlink port;
Step 3, terminal equipment carry out the configuration of network, fictionalize a VLAN Microsoft Loopback Adapter, now have two network card equipments;
Step 4, set up routing policy, make the transfer of data of different networks to different networks, thereby realize the access of dual network cross-network segment.
Further, described step 1 specifically comprises:
Step 10, on three-tier switch, select two uplink ports, and No. 1 port of called after and No. 2 ports respectively, the VLAN ID of No. 2 ports is set to 100, and the VLAN of No. 1 port is kept to default configuration;
Step 11, described two uplink ports are connected to two different networks by a netting twine respectively; First network in two networks of No. 1 port access, the second network in two networks of No. 2 port accesses.
Further, described step 2 is further: the downlink port of configuration three-tier switch, be configured to link aggregation trunk pattern by the mode of operation of the remaining port of three-tier switch, and the ethernet frame that is configured to allow VLAN to be 100 No. ID passes through, those remaining ports are downlink port.
Further, described step 4 is specially: configuration one routing table, and the data that make device end send to second network are passed through downlink port, then arrive second networks by No. 2 ports; Send to the data of first network by downlink port, then arrive first network by No. 1 port.
Further, in the time that No. 2 ports will access IPTV network, need carry out the operation of the multicast replication of travelling across VLAN.
Tool of the present invention has the following advantages: 1, can realize at any time, two kinds of networks of AB can be communicated with simultaneously.
2, user can use the application of A network and B network simultaneously, and the existence of imperceptible two kinds of networks, has improved user's experience.
3, reduce the complexity of network design, and reduced the cost of terminal and the cost of network design switch.

Embodiment
Refer to shown in Fig. 1 and Fig. 2, a kind of method that realizes the access of dual network cross-network segment based on Single NIC of the present invention, comprises the steps:
Step 1, provide a three-tier switch and a terminal equipment, the virtual LAN VLAN of configuration three-tier switch, makes the three-tier switch can at least two kinds of different networks of up access;
This step 1 specifically comprises:
Step 10, on three-tier switch, select two uplink ports, and No. 1 port of called after and No. 2 ports respectively, the VLAN ID of No. 2 ports is set to 100, and the VLAN of No. 1 port is kept to default configuration;
Step 11, described two uplink ports are connected to two different networks by a netting twine respectively; First network in two networks of No. 1 port access (as network A: the Internet), second network in two networks of No. 2 port accesses (as network B: IPTV private network or company's Intranet);
The downlink port of step 2, configuration three-tier switch, makes the data of two kinds of different networks be transferred to terminal equipment by this downlink port; Described step 2 is further: the downlink port of configuration three-tier switch, be configured to link aggregation trunk pattern by the mode of operation of the remaining port of three-tier switch, and the ethernet frame that is configured to allow VLAN to be 100 No. ID passes through, those remaining ports are downlink port; Those ports are the port of the twin spans of AB network namely;
